Andrewj Posted September 30, 2021 Report Share Posted September 30, 2021 I am installing a Fury in a BMW 330 ci with a M54B30 motor. From the original BMW wiring it appears the Crank and cam sensors have 3 connections, +12 volts, signal and earth. In a drawing on this forum I saw the earth wire appeared to go to a pullup resistor. Is that required? The motor has a single Vanos (2 wire) solenoid on each cam. The factory wiring had power to the solenoids and control switching the negative. No diodes could be found in the wiring. Do I have that right? The car will be a competition vehicle, should a delay off feature be added? Below is the wiring any advice on use of inputs etc would be appreciated.

Connect signal and ground direct to ecu, 12V from any ign switched source. 15 minutes ago, Andrewj said: The motor has a single Vanos (2 wire) solenoid on each cam.

Im not familiar with the M54, but assuming there are no diodes it will be fine wired the same way the factory had it. 17 minutes ago, Andrewj said: The car will be a competition vehicle, should a delay off feature be added? No, I would only do hold power for engines with a stepper motor idle valve, it just adds unnecessary complication. Quote Link to comment Share on other sites More sharing options...
