The manufacturers can improve their bottom line by limiting the engine power by the means of an ECU program, and then, without encountering additional development costs, they are able to produce more powerful models at a higher price. For most models, over development is avoided in order to reduce the development costs. As a result, engines and ECU’s from the factory are detuned and governed to be able to cope with a broad array of conditions.Īnother factor is cost.

Even the fuel qualities are not the same in every country. Once the vehicle leaves the assembly line, it must be able to cope with extreme temperature fluctuations, various climatic conditions, and other environmental factors. The two main factors that engine manufacturers aim for are flexibility and compatibility, as the engines need to perform in various countries around the globe. With chipping, we have to physically open the vehicle’s ECU, unsolder EPROM, and extract the chip manually in order to tune and reconfigure it, and then replace it into the vehicle, typically via soldering. In fact, remapping is simply a more modern approach to chip tuning. The Difference Between ECU Remapping & Chip TuningĬhip tuning, or “chipping”, is an ECU remapping alternative used for older vehicles – primarily for cars manufactured prior to 2000. With most cars, we are able to simply plug into their on-board diagnostic (OBD) port, – a standardized port present in cars post 2000, - and perform any required modifications. If these maps are recalibrated significantly, the vehicle’s engine performance and efficiency can be drastically improved. The map file extracted will actually contain several maps, such as Fuel Pressure Map, Boost Map, Injection Quantity Map, and others.

What is ECU Remapping?ĮCU remapping refers to the process of extracting the ECU’s standard software (the “map”), modifying it, and reloading it back onto the ECU. Through ECU map, ECU measures and constantly controls parameters, such as engine speed, fuel pressure, lambda and pedal position, boost pressure, cam timing, and more. Vital signals from the engine sensors are continuously transmitted to the ECU, so that real-time adjustments can be made.

Did you know that you can enhance your vehicle’s speed, power, and fuel economy in about 30 minutes with professional ECU remapping performed by the specialists at MA Performance?Īll modern vehicles are equipped with an ECU (Electronic Control Unit), which sends the standard signals to the engine, as well as monitors and regulates all of the engine functions.
