Need help to Bmw M20b20 12V 1986
Problems
The car is not making the amount of power it should (norm 300 hp) and it make knock.
Using wasted spark MSD 8224 dual coils
Trigger 60-2 org. shielded cables.
Fuel octane 95 (normal)
As I can see the deference in individual power (gauges) is big also in the log we see some wave or spikes in rpmĀ“s
ItĀ“s like the ecu due not fire correct at all cylinders but only some hit the right spot.
Trigger ref tooth (VT default m20) is 0-20-40-0-20-40 should it be 0-20-40-60-80-100?
Trigger log looking bad.
