Can we ask why??

Is it for performance gains??
kingliam
hi its a yes and no when i do motorway miles the trip says i am doin 67 to 72 mpg ford said it may need the fuel turned up because it may be lacking power and yes to the performance gains
TDCiST
first thing i would do would be to get your car on a rolling road, the operator will be able to tell you if things like that are wrong... you will also see if you are lacking power.

with the TDCi i'm pretty sure any fuelling changes will need to be done at the ECU. It seems a little odd to me that ford have told you to turn the fuel up...

what symptoms have you got, it may be another issue.

I'm guessing you have the 1.8 100 or 115 TDCi engine..

i would never rely on the trip computer to tell you how many mpg you are getting. have you tried calculating your mpg by filling the tank, doing a few miles and then refilling?

I find if i do 50mpg on the trip computer... calculating it on a full tank, i am actually getting 47-48ish... not far out, but makes a difference

on the tdci all the fueling is done through the ecu after reading all the various sensors, the only way to alter this is by remapping the ecu or a tuning box.

Agreed.. but would this actually fix the issue?? I cant see why ford would say "turn the fuelling up"... so they are actually condoning remapping of their ECU's?? Most manufacturers have been fighting to get remmaping banned, trying the whole "the software is ours, and your altering it illegally" argument!

Silly i know!!

Anyway, id be first looking at fuel blockages, damaged fuel lines etc, before storming into a remap!

hi i have looked a bit deeper it is doing about 55 to 60 mpg on the m25 today i have changed the fuel filter . when i phoned up ford the man said the fuel may need turnin up the engine is the 1.8 115bhp its done 83000 i have put on about 4000 miles in about 6 weeks i have been told it may be the intercooler blocked thanks
TDCiST
If i'm being honest, i know many 1.8tdci owners that would love that MPG! its known to be a bit of a drinker when it comes to economy lol!

yeah or could be a boost leak maybe...
kingliam
yer i cant fault the eco of it and we found out to day that the intercooler top were the air comes in was blocked with leaves and crap and the intercooler hose was lose its a lot better now thanks all for your help
