Hi,

I decided to get myself a tuning box off ebay, CR-box 130bhp - 163 bhp.

 

Has anyone already tried these? if so what do you think?

 

I am not really looking for better mpg as stated in the advert etc although that would be good! but I am more interested in a bit of a power gain in the higher gears, the standard Mondi 130bhp seems to stop spinning as wildly when it gets into fourth gear and the torque also seems to drop off a bit, soooo, for £59 english pounds I thought I would give this a go?

 

I had a 2004 Mondeo Black estate(150 bhp) (full leather etc) a couple of years ago and it did seem to gather much more momentum through the latter gears so I am thinking this tuning box may give me a similar experience?

I will wait for the box and fit it and put my response back on this thread for those that may be interested!

Cheers.

i have never liked tuning box's,always gone for a remap its better all round... tuning box's just con the ecu...But has i havent had one either for my mondeo (first one ever) as i have just swapped it for my beloved mgzr diesel so love to know how it goes

Huddersfielder
I've literally just put one on my focus this evening. Could not recommend it enough! It's a bluespark one. I had a mondeo tddi and fitted a dtuk box which was also very good too. Remaps are great but need to be done properly by a good mapper
stooge75
Ive had lotsa remaps. Its the same thing. Dont let anyone tell you different. Both remap and box just increase fuel/air. One does it by fooling the sensor and other does it by changing ecu parameters etc. same thing really. A lot of remap guys wont touch boost etc. Even got my golf done by a guy that said he WOULD increase boost/err impossible on that model (tdi 101bhp pd)
bladeage

....still waiting in anticipation for my delivery of the said box from Germany!

stooge75

let us know how you get on with it.was that box the economy one or performance one? I'm keen to know how much smoke you'll be putting out after ,say 3 months. I put one on my 406hdi,& it spewed out smoke something terrible. I see theres companies that are guaranteeing folk "No Smoke",but dont see how its even possible unless its a bluefin type chip or more expensive box

Huddersfielder
The dtuk box I used on the mondeo made it smoke a fair bit under load. At the time I put it down to it having 170k miles on the clock ;)
stooge75

I dont think its to do so much with the mileage,as it just overfuels the engine. As it doesnt make changes to the turbo boost,there's probabaly just too much fuel,& not enough air. I found that the turbo seems to take a bit of a hammering with them also,whether its with increased temps etc,i dont know.(mind you that was on an HDi engine so....)

Your post seems to contradict itself -  How can "the turbo seems to take a bit of a hammering with them" when you recon "it doesent make changes to the turbo boost" please explain?   

Huddersfielder
It will be interesting to see what it does on the focus, as its a PSA engine which is more or less the same as a HDi I'm led to believe? It'll be back on eBay if it starts to make it smoke like the mondeo. Its supposed to be a blend of performance and economy, and produce 165hp and 387 nm of torque. We shall see......
stooge75

was down to egr gases/temps going thru turbo. Mind you the hdi engine i had was only a 90bhp,so not enough intercooler/cooling etc. But I AM 100% positive there was not a thing wrong with the turbo before I upped the hp as we put new seals in it etc. Put it this way,the amount of oil in the in the pipe coming from the turbo was unbelieveable,and there wasnt any(when i say any,I mean there was no oily liquid,just a typical sheen,so to speak),just approx 2.5/3 months before.

I see what you mean,after re-reading my post back,& have to say,I'd have asked the same question.

Also,at the time,I thought my hdi ran too hot when booting it,therefore temp increased. Its only recently I learned there was a failure of the cooling fans on some models,but will never know now.

actually now i think back,that 406hdi was thee best car Ive ever owned. Managed to get 138bhp from a 90 lol(maybe a tad on the steep side) :huh:

bladeage

....Hmm as I understand???

my engine was designed to give an output of approximately 150 bhp as fitted/tuned to the titanium X in its finite tune, I thought this tuning box will follow the map for that configuration, it is a digital unit and only alters the fueling and timing etc?

 

It is apparent to me that some people have fitted these with existing engine problems i.e. blocked egr's, restricted manifolds, bad injectors.....anymore....?

My car is running great right now, no problems what so ever so will give it the go and see what happens,

Hi all,

 

Picked my CR tuning box up from the post office earlier and decided to plug it in while I was there, hahaha....big smile all the way home!

There wasnt really that much noticeable difference in first and second gear, maybe that is down to me not really giving it any in those two gears anyway but third fourth and fifth gears are now storming, the pick up is so quick and clean now, it wasnt really a slouch before I fitted the box but when you put your foot down now the power seems to come in instantly and the torque is much stronger,so much it is torque steering in third to fourth!

As above I would say that the 33 bhp gain that they claim is pretty much on the ball, I will not be taking it on a dyno etc to prove anything as it does now feel like a 160 bhp car, it certainly feels much faster than my missis's signum 150bhp elite so thats enough proof for me.

The claimed 20% better economy will take a little longer to suss out and I guess until I stop flooring it with a big grin and calm it down a bit then I will not be able to report on that.....it may take a while ! :D

 

First impressions are that it is a bargain at the £59 delivered I paid, and the power gain is correct,there does not seem to be any jerkyness or smoke or rough idle,holding revs etc.

I will continue using it for a few weeks and report back here on any changes etc.

cheers.

FOCA

Sounds like a bargain at £59

stooge75

have you got a DMF or SMF on your car?

bladeage

no dmf on my car it is an old shape 2007 duratorque.....what is smf????

 

I am kind of being a bit suspicious at the moment so I welcome any reteric or skepticism  etc regarding tuning boxes and what problems they may cause, it is good to discuss experiences when using different products that are available.

 

At the moment I can only report back what I find with this modification over time; I am not expecting the 20% better efficiency claim and to be honest after the power hike I have now I will be happy with 10% less fuel economy, my own usage of this car is commuting down dual carriageway for 12 miles each way and stop and squirt at weekends (I do m/bikes for fun!), and was only really looking for a bit more bite in 3rd,4th,5th gears which I now deffo have !

I owned a mondi estate titanium x Black a while ago which was 150 bhp and now this car seems to be acting in the same manner as that did.......torque steer and very clean and quick to pull through the box...but a bit quicker! I can only say after the 20 miles this has been fitted that I am 100% happy that the claims so far are bang on the mark and I could not find any niggles whatsoever.....lets see what a couple of weeks commuting does?........big grin....much power!

Like you said m8, it was always worth the punt, took your word for it and I am very impressed up to now with what I have driven today.

....see how it goes eh!  ;)  (much better! :D )

Hi m8,

Sorry I misunderstood your post completely, very sorry! (skipping between sites!), I have got a DMF on my Mondi as far as I know!

 

The car has 106k up now and is running great apart from the rattle I have from the bottom pulley...must do that soon!

I changed my crankshaft pulley yesterday(10 min job with the laser tensioner tool plus my impact gun. But it hasnt cured rattle. Im away to buy an INA alternator clutch pulley & upgrade it.
Done my egr as well,and it was in sorry state.was too cold to attempt inlet manifold so might do that today
bladeage

Ok chaps,

 

Before I set off from work today I reset the economy counter (real time mpg readout).

 

My economy display which I have reset a few times on my commute to work usually read 45 mpg, if I give it a bit of right foot this drops to 44 mpg.

 

The display is now showing 49 - 51 mpg, that is an approximate 10% gain in economy on my commute, I am betting that it will show a 20% increase on the motorway.

 

Excellent I think! 

stooge75
Well sounds good but our mk3's dont have real' time read-out,only overall average. If you reset it just as you are on mway etc,it wont really be a true reading,because of no traffic-lights,stopping,queueing etc. i know what youre saying though,& sounds good i admit.
I did same thing today-after cleaning egr,renewing oil cooler stat& water stat,i took it for drive up motorway & reset mpg readout. Normally it'll sit at 47/48 overall but as i reset it on motorway,by time i got home it was reading 56.something. So without any tuning box,i had a 16%(?) increase.
See what i mean?
Its back down to 48.1 after driving about city centre for an hour tonight.
Another thing,some tuning boxes ive heard (but cant see how its possible),fool the mpg readout andmake a false reading. But i cant see how thatd occur as its only having an affect on fuel delivery and not the guts of the ecu etc. mmmmm

Well scince you asked-

 

Some tuning boxes increase the fuel pressure of the common rail - this means there can be (is) more fuel squirted into the engine than the ECU "thinks" there is so the calculations the ECU makes can often be more optomistic (instant and/or avarage) than without the tuning box (depends on the type/ design of tuning box)

 

So the ECU is only as accurate as the information supplied to it

 

The MPG readout may be inaccurate anyway and you need to do traditional "brim to brim vs miles" checking of the MPG

 

Nevertheless the tuning box often improves the >>actual<<  MPG (on a turbo-diesel) because the extra torque means less throttle is required and the car pulls better up hills or in a higher gear etc

....lol.....it really was only ever going to be a bonus if the car was better on fuel, I have got what I originally set out for and that was a simple power hike in the higher gears, never the less I will monitor the fuel consumption closely and report back.......still very impressed with the extra power/torque !

stooge75
Interesting......
But the ECU knows how much fuel is being used as the tuning box is telling it how much fuel to inject.(well,in a sense). Tuning boxes are only really kidding the engine through fooling the ECU (by saying its cold outside,increase fuel).
So therefore,the ECU knows how much fuel's being injected(but doesnt know its actually a lot warmer than the tuning-box is telling it).
Thats why tuning-boxes arent good in long-run for fuel-pumps,injectors,cylinders,turbo's etc,as the engines running too rich.
Getting more torque thru lying to the ecu,i get,but is the extra mpg/torque worth it at the expense of the engine going through quite a fair bit of 'over-everything'.
Thats why a remap on a some cars(where the turbo boost isnt physically able to be increased) isn't the brightest idea for engines. The cylinders run hotter,so does virtually everything else(and richer);as they still have the same amount of boost from turbo(as its non-adjustable), but increased fuel input.
Im terrible at remembering things & have forgotton where i was goin with this lol

Mostly, this is nonsense - or little bits of information about completely different types of tuning boxes and forum "rumours" mixed together

 

Tuning box type # 1 - IAT tuning box The signal from the Intake Air Temprature sensor is modified so that the ECU "thinks" it is cold, (or colder than it is) and makes the engine run richer, simple/ works well (to an extent) with early petrol NA or turbocharged non cat cars, can contaminate cats on modern petrol cars with cats, works on diesels/ turbodiesels but there are better techniques - this is the only type of box where temprature is part of the control (ie - "its cold outside - increase fuel") - this may be a resistor of the correct value

 

Tuning box type # 2 Diesel common rail pressure boost type tuning box - Connects between the common rail pressure sensor and ECU, increases fuel pressure by modifiing the sensor signal so it reads LOWER than it actually is, ECU automatically compensates, so a larger amount of fuel is injected per cycle, exept the ECU "thinks" the same amount of fuel was injected as before the tuning box was added

 

Tuning box type #3 MAF sensor type- In a nutshell the MAF sensor measures the amount of air going into the engine, although it may be pressure and temprature compensated its function is to measure the amount of air (Mass Air Flow) -

 

(turbo-diesel)The tuning box connects between the MAF sensor and the ECU, the signal is modified so that the MAF is measuring more air than it actually is, the ECU squirts more diesel in to compensate, this can produce a  with a significant power and torque gain as the extra fuel boosts the energy in the turbine, which has a knock-on effect on the compressor, although peak boost pressure is controlled by the actuator (so the absolute peak boost pressure is theoretically the same as before) the boost comes in sooner, and the turbo spools quicker, with more boost across the entire powerband >>so the boost is changed INDIRECTLY with this type of tuning box.

 

Tuning box type #4 - Digital microprossesor multi channel programmable tuning box with multiple maps and direct control of the electronic actuator. the title says it all really, this is a realatively sophisticated box, effectively a second ECU, takes over several sensor signals, etc  this type has direct control of the turbo boost pressure, (engines with electronic actuators, obviously)

 

There are many different variations of these, including, "passive" resistor boxes, active analog boxes, digital, digital programmable with multiple maps, multi- channel digital etc etc

 

My (turbodiesel) car runs very cool (about 75degrees) if it ran hotter i would be happier (and i would get a better MPG too, apparently)

 

There is a school of thought that says increasing the power+ torque of an engine (ie- fitting a tuning box) REDUCES the stress on the engine, as it does  not have to be worked so hard, to achieve the same result              

bladeage

Excellent post FOCA !

 

I for one I did not realize there were so many different ways and outcomes that tuning boxes offer!

 

I guess I have one of the cheaper ones (£59) and it does fit to the common rail sensor, I do know it is a digital one as I specifically asked the question as per your prompt to do so.

I have noticed today that because of the extra power/torque when I am changing up then when I get into fifth and eventually sixth on occasion then I seem to need less throttle to keep it at that speed.....I guess what I am saying is my foot is not pressed down nearly as much when I get into the upper gears and infact in fifth gear now on a flat road my foot is hardly pressing the accelerator and now only needs a very slight press to overtake etc.

 

I did notice something slightly different this morning though and that was the sound of the injectors were a bit louder, perhaps they sounded a little bit more clattery (the tdci noise) however 2 miles down the road when warmed up properly everything sounded normal again, maybe the injectors dont like the extra fuel until warm?? Are the injectors in the 150bhp version the same as the 130bhp? p.s. it was awesomely freezing cold this morning so it could have been just that!?

 

cheers :)

Huddersfielder
I'll be honest I took mine off my focus last week purely because of the extra noise the injectors made when started. Was worried about the extra load the injectors were under, now I don't know what to do for the best!! Try again or sell the box!
Huddersfielder
Oh and it was very cold too -3 degrees...
bladeage

Thanks for the info m8, it seems I was not imagining the clatter then!

 

It maybe that the extra fuel on a cold start up requires more air than the air filter is allowing; I have done some thinking and think that I am going to remove the air filter for a couple of days and see if there is any improvement in the noise on a cold start up, it could be the old problem of.....how do I get more air into the tight space I am now flooding with fuel!??

 

Like I said, when my engine is warm the clatter almost vanishes totally so I am guessing that the ecu when being fooled by the piggy back when the engine is stone cold maybe isnt able to compensate properly for the fuel being added, therefore possibly a messed up ignition map is happening until the ecu recognizes a temperature variant or air flow it is familiar with when the engine and sensors are warm>????

Sorry, I am not a mechanic/engineer but do like to get involved in stuff like this.....lol....twin carbs and two litres were always much easier to fathom!

I am sure FOCA  will slowly shed some light! :D

FOCA

No pressure LOL - the Ecu adds a bit of extra fuel for cold starting which is "superimposed" on the extra fuel the tuning box adds, there may be a bit more smoke when you start as well

 

The clatter may sound a bit taxi/ transit - like but its ok, unlikely to do any harm - if there is a lot of smoke when you start it up and or when you "boot" it it may be worth talking to/ discussing this with your tuning box suppliers to try different settings maps etc/ or have it reprogrammed

 

if the clatter goes away/ settles down soon after starting i think it should be ok, this may not happen in the summer

 

A long time ago i ruined a metro turbo engine by experimenting with no filters,(wore out the bores with grit/ sand) i would never run a car on the road without an effective air filter now

 

Try a new, pattern filter every 6 months, a K&N pipercross panel filter,  should run a bit better with the tuning box fitted, i cannot guarantee the "rattling" will stop (in cold weather, anyway) 

 

Also try ressetting the ECU (if you have not already/ if you change somthing - tuning box/ filter etc) it can make a big difference

 

Does the "rattling" happen when you start the engine (without using throttle) or when you 1st pull away (1st time you open the throttle in gear with the clutch up ) ?     

Huddersfielder
That's good to know! Mine was just as it had started with no throttle, but mine also stopped after it had warmed up. Might connect it back up tomorrow now, cheers FOCA! :)

I told you what happens with that tuning box but you dont want to take advice.
Oh and by the way,its not your injectors you hear.
Ive done ALL this before on stronger cars than fords and they ALL end up fubar'd!!
When are you guys gonna take good advice for christs sake.

You were the same with solid flywheels -

 

Tuning boxes are like anything else, they are fine if set up/ used properly and can cause damage if abused (for example if they are turned up too much or fitted/ set incorrectly)  

 

When there was a poll on another site/ furum, "tuning boxes, good or bad" the "Pro" tuning boxes outnumbered the "con", with many Ford owners using them for years with no problems, most of the Ford owners that were "against" tuning boxes had not actually tried one/ fitted one to their car

 

Im the 1st to admit that a good remap is better (in most ways) than a tuning box, but with a remap costing as much as £300-500 and bladeages tuning box costing £59, its a "no brainer" :)

Hi  :( ,

 

Just signed into this thread I started and it seems tempers are fraid somewhat?

I didn't really intend for anyone to fall out over the subject and I can assure all parties that I and many others have been listening intently to "all" the advice given,all advice etc was/is very welcome on the subject.....absolutely!! :)

I guess we are all here to gain information on the cars we drive on a daily basis...and mostly...there are certain posters here that offer excellent advice and opinion which is based mostly on either/or, experience and practical theory, without these people then the lesser experienced people on here such as myself will not benefit except for stabs in the dark sometimes based on mis-information. (I speak of FOCA and STOOGE 75 being excellent contributers!)

 

I for one have learned loads about fuelling and how these piggyback units work now!

 

Anyhow...........

 

I left the car over night and started it up around 2pm, the diesel rattle was not there at all so as a guess I think that the outside temperature has some bearing on the said rattle (what is the rattle stooge? :) ), soooo....guessing again...when it is very cold the ecu compensates with more fuel to get things going and with the piggyback unit telling the ecu it is already cold and to add more fuel/pressure then the ecu either gets confused and I am just over fuelling the engine which is now running out of time for the amount of fuel being added.

I can see if this is the case that it would be much better to have a full remap!

 

We went for a meal 40 ish miles round trip on the motorway and the car was averaging 60- 62 mpg at 72 mph, funnily enough when you let it come down to 68 mph then the mpg dropped to 58-59, my missis's Signum Elite does the same thing also and I now think they have a sweet spot for best mpg!???

My commute is still returning between 49-53 mpg on A road and city stop starting (24 mile return journey), I have not yet done a scientific calculation with brimmed tank to empty but I do think the gain is looking to be correct on the 40 quids worth of fuel I put in last week, and I really do know that My right foot is well backed off to the point that I am feathering the accelerator pedal at minimum on flat roads to keep it at speed.

I think you may have guessed I am not a thrasher and I have to be honest that if I were, then I think the extra noise the car makes if you put your foot down in a morning when stone cold (-0) would equate to damage if repeated on a regular basis as it is obvious there is a fuel/timing issue probably resulting in the cylinders being hydraulicked on a very cold start up,knowing this I have backed right off at first until the engine is warm (as everything sounds normal that way!) and wait for a few miles until the engine is warm when everything is good and working great.

Obviously this is not an ideal situation and not one I want to stay with but I feel that with the warmer weather coming and the fact my driving is limited to slowish commuting anyway then I will continue to use the piggyback and keep reporting back.

 

Just something to take note of though.......

 

On cold start up before I fitted this box this sound was already there and the engine acted exactly the same way....but to a lesser,quieter degree! so deduce it is extra fuel being added by the piggy back.?

also....I have not once seen any smoke from the car before or after fitting and when warm (2 miles down the road) everything is very good, if it werent for the cold start bit then the £59 tuning box I brought would be and absolute bargain, as it stands right now, then I am reserving long term judgement!

 

How do I reset my ECU ????

cheers

FOCA

Hello again !

 

You reset the ECU by dissconecting your battery (20 mins should be enough/ watch you don't loose your radio code) or you can disconnect a specific fuse (again for 20 mins) 

 

The car may run badly at 1st after the reset as the ECU "learns" then after a while of driving the ECU  will be "set up" for the changes (whether its a new tuning box or filter etc)

 

It may make the cold start "clatter" quieter but this sounds a bit like typical diesel "cold weather start up" to me - cold pistons/ cylinder head and a compression-ignition (diesel) engine that "likes" to be warm - perhaps the tuning box just makes it more noticable (more or less what you said)  - also, check your glow plugs  

 

The ECU reset may help the MPG or performance too, and may make the engine feel smoother

 

I can't remember if/when you changed your air filter but if you change it often it can help your MPG and help add a little bit more air to balance the extra fuel of the tuning box (some tuning box supplliers/ Bluefin sellers on e-bay sell filters together with them - because of this)

Hi,

There is no disputing the power increase and also the economy seems to be much,much better but I started the car this afternoon and on my return journey from work it sounded loud again,clattery and out of time, I drove on for a couple of miles and again like the morning starts everything smoothed out and we were back to full power and running smoothly.

I decided to remove the box mid journey and see if and what difference there was and found that it was much smoother and quieter without it, lots less power in the upper gears but it fealt more responsive in 1st and 2nd gear,it could be that like FOCA said it needs more air via an up rated filter so as an experiment I am going to remove the filter altogether for one journey to work and see if anything improves, taking on board this is not such a good idea long term it will give me an idea if that is the way to go!

 

lol.....I really am only doing an experiment with this tuning box to see if there can be a happy medium achieved for the £59 they cost opposed to a £300+ ecu reprogram (as they are also not guarenteed!!), the deal so far is that it works well in the higher gears and economy is the stated 20% better ish they advertise and but for this glitch when starting from cold then I would say everyone should buy one, but there is definitely an issue with cold starting so cannot wholly recommend one at this point!

 

I must say though, if it is overfuelling then I am not seeing this in the form of black smoke out of the back....no smoke at all!???

cheers :)

stooge75

I'd say if your engine is in good condition,then you shouldnt really see any black smoke,apart from when its under load & EGR opens,which is normal. Its not a good idea to remove your filter mate. Any foreign debri that goes up the intake is not going to be good for engine,turbo etc. I have removed an air filter & ran it like that before,as well,but still not good practice :P

FOCA

Ive got to agree on this point, removing the filter is not a good idea, sand and grit, small stones, debris  can find its way into the filter box, without the filter these things could damage the valve seats bores and pistons/ rings, contaminate the MAF sensor, damage the compressor wheel, clog the intercooler  

 

Ever been driving along and a small stones hit the bumper/ grill/ edge of bonnet, screen etc? without a filter this could go into the engine/ all the above the time you don't have the filter on, could be the time you need it most 

 

Just buy a new panel filter - about £10 online for a pattern one - i use one and my 2.0L puts out 160Hp & 368Nm

 

if you took a stock/ pattern paper filter and spread it out flat, it would be massive, the folded design gives it a large surface area, not alot of people know this, but the air intake may be more restrictive than the (if its new/ clean) air filter element itself  

 

 

There is a tuning box from Italy that has a remote control as an option, (i think i may have recommended it in my PM) you could have started it with the box switched off, warmed the car up a bit then switched it on as you drove - to have the best of both worlds 

 

You could have the tuning box plugged in on certain occasions and removed for others

     

Its always your choice to have the tuning box removed, it depends on your priorities

Thanks for all the posts on this folks,I have decided to remove it for a while and may refit and try it in the summer,its obvious there is a problem with cold starting/running and to be honest I really should change the glow plugs as it has always been a bit clattery on start up with or without the box, maybe that is being exaggerated by the box? who knows?

 

Now removed the car has dropped back down to 45mpg tops but until I learn more then it will stay off due to the poor cold start problem.

45mpg...from a 2 litre....bargain! :) 

Thanks again all!

.....not wanting to harp on!

 

Do you think the glow plugs could be causing the exaggerated clattery starting in the mornings as it still does it to a less degree without the box.

No smoke etc .

Hi New to forum. I have had a DTUK CRD2 for 4 years without any bother. But i now have a CRD2+... could someone tell me if the wiring loom/harness connector that fits my 2004 TDCI 1.8 focus engine would also fit the connector on a 2011 TDCI 2.0 (163) focus engine... Also what info would you have about using the CRD2+ and the DPF on the above 2011 car... Thanks

Hi - they are very different engines, so i doubt it - often tuning boxes are set for each type of engine and even if the connectors are the same it may need set differently - speak to DTUK - they may help you with this

Hi Yeah, i did ask DTUK... they give auto `answer you back in 24 hours` blurb but they dont ... maybe i should put `I send cash quick` in the header to get a response...lol

Temperatures are up today and I found when I started the car from cold this morning that all the clattering had disappeared so I am thinking my glow plugs need changing, which I am going to do then re fit the tuning box and try again!

nothing to do with glow-plugs. it'll be your cam(lifters) or something.

I get this as well,when engines cold for 1st few minutes. I used comma oil last time & wont ever use it again as i never had a squeek before the oil change.got myself a Ford dealership oil this time.let you know how it goes after an oil change.

Mabee its your teeth chattering with the cold lol

 

I agree that fresh oil change with quality oil can quieten the top end down a bit but there is no hiding the sound of diesel combustion with a cold engine on a cold morning

 

A Mondeo has (almost) exactly the same engine as a Transit or a London black cab/ taxi - so now you know why it sounds like that!  

 

Try a mazda petrol v6 - so quiet i often tried to start it when the engine was already running! (was'nt my car, it was brand new/ i worked at dealarship)

Hi,

The clatter when it was cold outside last week and before then actually retarded the power, i.e. it did not accelerate as quick as when warm, I take it from the above two posts that the lifters are hydraulic, if so then the quality of oil would make a big difference in the cold so next question is....do I put Mobil 1 in or similar for cold weather running?

cheers
