have to check nistune about the rpm, the one who mapped the car doesnt remember what he saw on nistune.
but also tried another ECU with nistune, that works for my m8 - nothing for me tho.

NEW VIDEO:
tried another cluster, and this time the needle jumps to 1000rpm and stays there until engine is off.
without the 10k resistor nothing happens.
