The RaceROM Controller is a driver-adjustable input to the Custom Maps system. The driver can select a value using the cruise control buttons and it is displayed on the oil temp gauge. The tuner can create a custom map to adjust any of the engine parameters based on the driver’s input. This could be used on a forced induction car, for example, to select a desired level of boost. It can also be used by the tuner to provide a certain amount of live tunability.
