Please Help M50B25nv no crank no start
« on: June 07, 2020, 12:56:18 pm »
Hi,
Just installed my new  VEMS V3.8 with 3.6 board plug and play ecu onto my M50b25nv engine. Not sure why, but I have a crank no start.
If i plug my stock ECU in, the car fires right up. Could there be something wrong in my config? Or maybe inside the ECU itself?

Any help is appreciated. Need to fix this ASAP

i have some triging logs

Try reversing polarity on cam signal and take a log again
