ECU remapping

fapfapfapfapfap

So lots and lots of places are promising increases BHP and fuel economy. Sounds too good to be true like some sort of tacky gimmick. I'd assume the stock ECU is designed to maximize longevity of the component and keep things within a certain tolerance? I can't imagine a manufacturer would purposely cripple their vehicles, reduce fuel economy and shut down power?

Any thoughts???

Another pointless thread for your research project? Or are you going to contribute more than one post to this one?

And yes in these days of cars produced for a world and not a local market a very conservative map is often used by manufacturers to allow for variations in fuel quality/servicing intervals/emission requirements etc. etc.

Even I know what it means in English

Clearly that is not true. Every car you see one the street, unless it's an import, will be configured to meet UK specific requirements - the most obvious parts of this being the steering wheel on the right hand side and the configuration of the lights.

By comparison implementing a region specific ECU map is easy and I'm pretty sure manufacturers will tune their ECU maps to the local market.

The U.K. Isn't unique in driving in the left, around a third of countries across the globe do so, depending on whether you're looking at number of countries, size, population etc

So you agree, there is no such thing as a global spec car?

No. The Ford Focus for example is a global car.

Yes, there is. If for example you'd have bought a Ford Focus in the US a few years ago you'd have got one of these



Designed and built in the US and not even bearing a passing resemblance to the MK2 available in most of the rest of the World.

Now everyone, be they in the US, Europe or China gets this.



That is what I mean by a global spec.

I think you'll find if you drive a focus in a different country (for example the US) the spec will be different. Different lights, different suspension tuning different in car electronics (or at least the software part). The engines might also be tuned differently to take account of local emissions regulations.

Cars go through a significant amount of configuration changes in preparation for sale in different regions to meet the requirements of local type approval as well as the tastes of the local market. It's no big deal - manufacturers do this all the time so why would anyone expect them to stick with a one size fits all ECU map (which was the original point).
