installing VEMS V3 on BMW engine M73B54

I'm using crankshaft sensor VR with 60-2 tooth and waste-spark ignition

I have issue with the crankshaft sensor. During cranking I can't see any readings from the sensor.

What setup do I need to make to the ECU?

I directly connect the sensor to the VEMS on PINs 26 (GND) and 27 (VR +). I test it in both directions (I swap the two wires on pin 26 and 27) and no improvement.


Ground connections ?

P259 outputs are OK ?

Hi,

I'm wiring the engine and the ECU (testing the connections).

I connect GND on pins 5 and 32 directly to the batt.

I'm reading TPS via VEMS software on laptop, but I'm not seeng any readings from the VR sensor (during crancing).

I don't connect anything to p259 yet, I will conect fuel relay on pin 15.

Can you give some recommendations for the configuring the ECU (to this moment I didn't make any adjustment of the ECU). Maybe that is the reason behind that I'm not seeing any data from the VR sensor.

Thanks in advance

Br.
