"Chip tuning" as it is commonly known, is the art of modifying the standard ECU software, which is stored in the factory engine management system, otherwise known as the ECU. The vehicle has to be equipped with an electronic engine management system in order to take advantage of an ECU upgrade.The development of the software is based on extensive testing on most common vehicles and engine configurations on a MAHA LPS 3000 chassis dynamometer.

Chip tuning means that the standard software is modified, especially the parameters relating to power, torque, and fuel economy. In order to increase the power-output of engines, it is important to change the timing and amount of fueling, ignition timing, and turbo boost on turbocharged engines. By adjusting these parameters, the engine will have the upmost efficient combustion required for power and ecomony.

By programming a well balanced combination of fuel, modified ignition-timing, and where applicable raised turbo boost into the standard-software, an increase in power-output of about 25-30% can be achieved, combined with a smoke-free vehicle and improved fuel economy of about 5-10%.

Please see the relevant section for the ECU upgrades currently available. Reprogramming via the OBDII port is available on various models. For the cars that can't be repprogrammed via the OBDII port, the ECU upgrades will be "chipped" which means that your ECU upgrade will have the original chip reprogrammed using an EPROM programmer.
