The S1 EU2 VVC is controlled by the Lucas MEMS 2J ECU common with the early VVC MGFs

The S2 EU3 VVC is controlled by the Lotus K4 ECU (based on the Lucas MEMS 3)


VVC Failure Modes

ECT Sensor Error Limits to 6K RPM

MAP Sensor Error limits to 6K RPM

VVC Solenoid low resistance (should be 6.6 to 8.8 Ohms)Limits to 5.5K RPM

Cam Position Sensor Limits to 5.5K RPM

Note: Connecting the battery on wrong polarity can blow the ECU VVC control circut, as can running with a low resistance solenoid. Clearly the circuit has no protection.
