The VENOM 400 constantly monitors the vehicles throttle position senor (TPS) and manifold absolute pressure (MAP) or air mass sensor (MAS). When airflow entering the engine and the throttle position sensor reaches a predetermined level, the VENOM 400 is activated. The VENOM 400 then enters a strategy of sense and modify. It senses the sensor values, interprets them, then modifies them to increase performance. The existing on-board computer senses the modified values and increases fuel flow, modifies the ignition spark curve and transmission shift point (on automatics only). Once the sensor valves return to normal mode (like idle), the VENOM 400 switches back to sense only mode until conditions again warrant the high performance mode.
