Why Choose MAPECU?


Performance with Economy

More Horsepower, more Torque


MAPECU3 is our 3rd generation piggy back ECU that not only allows you to tune fuel, ignition timing, etc., but it also adds performance and safety features to the OEM ECU that “chipping” or “reflashing” cannot add. For example, Flex Fuel, speed controlled launch control, nitrous activation, electronic boost control, lean boost retard, etc.

One of the unique things MAPECU does is allow you to remove the OEM airflow meter, e.g. MAF, and convert to MAP for freer breathing. Essentially MAPECU3 sits between reflashing and a full standalone ECU. With OEM manufacturers tightening security measures restricting reflashing through the OBD2 port, MAPECU is an ideal way to tune your vehicle for optimum performance without resorting to modifying the OEM ECU. If you need to put your vehicle back to it’s stock configuration you can with no tell-tail reflashed program in the OEM ECU. Some of MAPECU3’s features include:

  • NEW Flex Fuel feature for realtime Ethanol content and temperature tuning
  • Optional WiFi interface for wireless connection to our iPhone App (iMAPCAL)
