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.
