Custom Maps


RaceROM Custom Maps allow the tuner to modify the behaviour of the factory ECU by inserting additional maps into the ECU's normal calculations for parameters such as ignition timing, fuel, boost & VVT. It also allows re-purposing of inputs and outputs to measure custom sensors or solenoids not featured on the standard vehicle (Flex-Fuel, EGT, Oil or Fuel Pressure for example). 
For more information on these powerful and unique features, see the dedicated Custom Maps Manual. See below a few examples of what is possible using Custom Maps.
