What exactly is an ECU Remap?
An ECU remap is a technique of enhancing typically the electronic engine supervision system of a car by upgrading the program installed by the manufacturer. The ECU (electronic command unit) is current with a different set of directions that help the particular engine generate more power and operate more efficiently.
Car manufacturers mass produce engines for make use of in countries all over the world and this means they need to be designed to handle a range of different operating conditions, which includes different grades involving fuel and several climates, but there are other demands including the have to have to reduce dangerous exhaust emissions. Manufacturers will often course the engine command unit so that will the engine will be capable of completing the stringent emissions tests with a low emissions value, meaning the auto will match some sort of lower road tax and company auto tax band, but this is not necessarily necessarily the best setting up for that motor to run from its best in the real world.

This kind of gives an engine tuner the opportunity to increase the efficiency of the engine by simply reprogramming the digital control unit to be able to make the just about all of the marketplace in which that is being utilized. By simply programming the engine to run together with the specific grade of fuel and the air temperatures associated with the car's residence market it may gain better throttle response, generate even more power plus torque, and in many cases employ less fuel.
Nearly every car that offers an electronic engine management system could be provided an ECU remap, and that applies to both petrol plus diesel engines. Results can vary yet an ECU remap will always produce the best benefits when applied to a turbocharged or perhaps supercharged engines. This particular is because bringing up the boost strain with the turbocharger or even supercharger allows much higher gains in power to be performed, when combined with the correct ignition timing and encouraging adjustments.
Nevertheless , it is sometimes probable to achieve considerable power gains within naturally aspirated machines. Some manufacturers offer you the same motor in different models with varying levels of power, and this is completed by de-tuning the engine using a different ECU map. This will make it possible to remap the particular ECU to produce the particular same level involving power as the particular higher tuned version. get more info associated with this can be the 2. 0l petrol engine discovered in the Vw Golf, the de-tuned version of the same motor found in the particular Golf GTI.
Putting in an ECU remap is a comparatively simple task. Many new cars have a diagnostic dock somewhere in the particular engine bay or dashboard that permits mechanics to download error codes from the ECU once the car is in for service, and even this same port can be used to upload the particular new ECU remap using a laptop computer or special performance devices. Some older cars will require the original computer chip on the ELECTRONIC CONTROL UNIT to become replaced, which in turn requires more tech expertise and can easily make the upgrade more expensive.
Typically the actual power obtain from an ECU remap varies involving models. Some search engines may gain as few as 5% while several may gain while much as 40%, but typical increases in the electrical power of the engine would be around 15-20%. The more torque means gasoline economy can boost but this varies even more, generally depending on driving style and just how much of that will new power you really feel like using.
An ECU remap is one of the most cost-effective means of getting more strength from the car, in addition to on some well known models can cost only a few 100 dollars.
