On the other hand, if your vehicle is a working vehicle such as a van, truck or company fleet car that does a lot of miles, you might want to remap the ECU to boost fuel efficiency at a slight cost of performance. Any performance add-on will require a different ECU mapping to get the most out of it. If you have replaced some other parts in favor of high-performance parts on your vehicle, like a performance exhaust, for example, you might also want to have your ECU tuned to fit the new mods. For example, if you want more performance, an ECU remap can change the gear ratios, air/fuel ratios and fuel flow of your carвЂ™s powertrain to boost power, usually at a sacrifice of fuel efficiency. While these default settings might be the best generic setting for your vehicle overall, they might not be the most efficient settings for your particular requirements. When a car rolls off the production line, its Engine Control UnitвЂ™s software is set to a default that works anywhere in the world, taking into account factors like different climates, road conditions, geographical conditions, varying fuel qualities and so on. However, the ECU weвЂ™re specifically talking about here is the Engine Control Unit which controls things like fuel flow, gear ratios, engine speed, variable valve timing and so on.

A car might have up to 50 or more ECUs, which handle things like the driver interface, door locking systems, airbag systems and so on. An ECU, or electronic control unit, is a вЂchipвЂ™ with software installed with default settings for those functions.
