Trying to get VEMS to run in a plug and play fashion on a 1997 Seat Cordoba SX, with a 2.0-16V engine (engine code ABF). The sensors, actuators and required outputs are:
- Hall-effect type crank sensor on a 60-2 trigger wheel
- Hall-effect sensor on camshaft for sync
- Bosch coolant and air intake NTC temperature sensors
- Single dumb bosch coil triggered with external module, and with ECU controlled dwell (but swapping to waste-spark now so need 2 high current ignition drivers)
- Two bosch 3-wire knock sensors
- RPM signal from ECU to instrument cluster to drive tachometer
- 2-wire 4-ohm Bosch idle control valve
