Have made a table, but unsure about how to wire the knock A&B. Also unsure about the Idle Air Control Valve. It's a Bosch 0 280 140 545 1738 981. It has 3 pins. I guess one is ground, the second 12v supply and the third should be connect to injector #7 or #8? Q: I measured the trigger angle 60 degrees before TDC. I read: The value should been between 40-60 degress? How should I set this up then? Use another cylinder to refer to?
