The car has a 6 cylinder engine with the following sensors and actuators:
- VR crank sensor with a 60-2 trigger wheel
- Hall sensor on camshaft for sync
- Bosch coolant temp sensor
- Mass air flow sensor (to be eliminated) with air inlet temp sensor
- Throttle position sensor
- 2-wire idle stability valve
- dumb waste-spark coilpack
- rpm signal from ECU to instrument cluster tachometer
