Remap thoughts

Hey everyone, 

As I'm heartbroken from finding the previous owner lied about the car having a mountune remap I came across a company called Hdi tuning. They specialise in the HDI engines. These engines were made by the PSA group and are used in ford, Peugeot, Citroën, volvo, suzuki and mazda. They do a stage 1 remap upping the power to 115hp (standard is 90hp) and torque to 260nm (standard is around 206nm). All this for £150. They specialise in only the HDI engines so makes you know they know their stuff. 

This remap they claim is safe within stock engines and does not let the turbo over boost. 

Just wanting to ask how others who remapped their cars noticed any difference. This remap has 2 more hp but 10nm less than the mountune but is a bit of a step in performance compared to stock.

For £150 it's gonna be a generic map bought in.  Don't get a cheap map.i did that with my ecoboost and it died a death. 

 

If it sounds too good to be true, it usually is.

I had my car remapped today however mine isn't a diesel engine. I paid £400 for the stage 1 Revo remap. It ran on the dyno as 126bhp standard and the remap took it to 156bhp aswell as increasing the torque from 172 N.m to 230 N.m. Certainly felt the difference when it had been done. They also mentioned if I had of been using V-Power instead of normal unleaded, they could have got an extra 10bhp out of the map but I was happy with the increase as it was

They do mention about generic maps and that they aren't really designed specifically for the car plus how expert tuners can't get the best remap and Ecu combination. Here's just a description of the remap 👍

My issue with a generic map is why didn't Ford have the extra power available from the factory? Well I guess it's because it strains the engine beyond what it's designed for, and isn't reliable enough.

A tuned map should be made for your car. All Ford do at the factory is stick a generic map on, so having it tuned to your engine (they all perform slightly differently) means you get the best possible power without compromising too much of the reliability.

In an idea world you'd have an aftermarket ECU and a full rolling road tune. Obviously nobody on a stock fiesta would do that. It literally costs over £1000 for an ECU, and I'd say double it to include having it tuned (I've only quickly looked into it).

The 1.6 tdci engine does range in power for example with the focus you can get it with 110hp but I'm sure that has different injectors and turbo. The 1 litre ecoboost on the fiestas comes with either 120 or 140 horsepower. It's probably done like that for marketing. On their FAQ they did say it's safe.

Well these guys who you get unsolicited phone calls off from India claim they can make your computer "safe". If you were trying to get money out of someone, you're not exactly going to say it's unsafe lol. I mean they said the titanic was unsinkable due to the safety features it was supposed to have 🤔🤔.

The diff and head gasket is different on the 140 and 120. Any mapping company upgrading to 140 won't be using Ford's map, but yeah it is probably marketing reasons.

More complicated than that.  Car makers have to balance many demands and the standard manufacturer map is actually quite a sophisticated and well considered thing.

In deciding its map Ford would have balanced, among other things - how much strain its parts can take (will they get through the warranty period, particularly because parts are themselves built down to a price); the demands of customers in terms of fuel economy (excellent headline figures look good even if most of us know they are basically fiction); customer and government demands in terms of emissions (government rules on emissions levels across ranges, customers wanting lower tax); customer demands in terms of power and how it is delivered (we all want a quick car that's nice to drive); insurance groups (higher powered cars cost more to insure and this could drive away younger customers in particular; maintenance which could become more frequent (i.e. less attractive to customers) with engines in a higher state of tune.

Essentially all the default map is, is Ford's opinion/judgement on the optimum settings to strike the best possible balance of a lot of things. They would have spent ages debating all of this in design groups, board meetings, and all sorts of other places!

So they're claiming it's their own GENERIC remap... IE, they've developed it over thousands of miles but it's still a generic file.
