M42 Reference / Crank sensor m42 and m44

« on: July 03, 2010, 12:18:09 AM »

I had a M44 in my car but it has been replaced with a M42 turbo now But anyway, the crank sensor is of the same type on both M42 and M44 (VR) and the cam sensor is of VR type on the M42 and Hall type on the M44. M42 ECU will not work with a hall sensor. What you can do is put a spacer in between the sensor and the cam gear cover and use a M42 sensor, thats how I did and it worked. It was also before I discovered that the cam triggers are different and M44 cam triggers will not work with a M42 ECU But it doesnt matter as the engine will run fine without a cam sensor I could have removed it but then I had to find/make a plug so I just left it in there Maybe the CEL comes on if the cam sensor is broken/gone? Test to unplug the cam sensor and youll see

My m44 crank sensor is next to the starter pointing at the flywheel. Would this be compatible w m42 ecu where crank sensors are all mounted in the front?
