Adamw Posted May 4, 2022 Report Share Posted May 4, 2022 Trigger offset is a bit odd for a BMW. So with that base timing screen open and the engine running, your timing light shows the timing marks line up at 5 deg BTDC? And if you rev the engine with the set base timing screen still open, the timing mark stays solid at 5BTDC and doesn't drift away? Quote Link to comment Share on other sites More sharing options...

Adamw Posted May 5, 2022 Report Share Posted May 5, 2022 If the timing drifts more than say 1 or 2 degrees with RPM that would suggest something is wrong with your trigger or trigger setup. You would really need an oscilloscope capture to determine the problem. Denso and doctorloole 2 Quote Link to comment Share on other sites More sharing options...
