Crank signal issues Opel Astra c16se

[BMWCanary]

May be someone can help me with this problem.

Having connected the DET3 in a Opel Astra c16se with DELCO Ecu 16183109, the DET3 is not sensing the VR sensor at low rpm when cranking even setting scope mode. The engine does not start up with the DET3 connected.

Just starting the engine with the VR sensor connected to the ECU directly and when the engine is runnig at idle bypassing the VR signal to the DET3 is posible to have the DET3 working. It happend around 900 rpm.

My settings are:

VR signal to DET3 pin 9
DET3 pin 5 to ECU instead of VR signal.


Any idea???

Hi!

You need to connect signal in the following way (there is differential signal from sensor not single ended)
