What exactly is an ECU Remap?
An ECU remap is an approach of enhancing the particular electronic engine managing system of some sort of car by modernizing the software installed by the manufacturer. Typically the ECU (electronic management unit) is current with a distinct set of commands that help the engine generate extra power and operate more efficiently.
Auto manufacturers mass generate engines for use in countries across the world and this means they need to be designed to handle a range of diverse operating conditions, including different grades associated with fuel and various climates, but there are other challenges including the want to reduce damaging exhaust emissions. Companies will often process the engine command unit so that the engine will be capable of passing the stringent emissions tests with a new low emissions value, meaning the automobile will squeeze into the lower road duty and company automobile tax band, nevertheless this is not necessarily the very best setting for that powerplant to run in its best in the real world.
Continue reading of gives the motor engine tuner the opportunity to be able to increase the efficiency regarding the engine by reprogramming the electric control unit to make the most of the marketplace in which this is being used. By programming the engine to run with the specific grade regarding fuel and the particular air temperatures regarding the car's house market it can gain better throttle response, generate even more power in addition to torque, as well as employ less fuel.
Almost any car that provides an electric engine management system could be provided an ECU remap, and that relates to both petrol and diesel engines. Results can vary although an ECU remap will always generate the best outcomes when applied to be able to a turbocharged or perhaps supercharged engines. This specific is because raising the boost pressure in the turbocharger or even supercharger allows very much higher gains in power to be achieved, when combined along with the correct combustion timing and fueling adjustments.
Nevertheless , that is sometimes achievable to achieve considerable power gains throughout naturally aspirated search engines. Some manufacturers provide the same engine in different designs with varying amounts of power, and this specific is done by de-tuning the engine with a different ELECTRONIC CONTROL UNIT map. This makes it achievable to remap typically the ECU to produce the particular same level involving power as the higher tuned variation. An example regarding this can be the 2. 0-liter petrol engine identified in the Volvo Golf, the de-tuned version of the same powerplant found in the Golf GTI.
Putting in an ECU remap is a relatively simple task. Most new cars possess a diagnostic dock somewhere in the particular engine bay or perhaps dashboard that permits mechanics to down load error codes by the ECU when the car is in for service, in addition to this same slot can be applied to upload typically the new ECU remap using a notebook or special performance devices. Some elderly cars will need the original chip on the ELECTRONIC CONTROL UNIT to get replaced, which usually requires more tech expertise and can certainly make the improve more expensive.
The actual power gain from an ELECTRONIC CONTROL UNIT remap varies among models. Some motors may gain as low as 5% while a few may gain while much as forty percent, but typical raises in the strength of the motor would be all-around 15-20%. The more torque means energy economy can boost but this varies even more, largely depending on traveling style and just how much of that new power you really feel like using.
A good ECU remap is among the most cost-effective methods for getting more power from your car, and even on some mainstream models could cost only a few hundred or so dollars.
