Ign trigger cyl3 over crank signal 2000rpm
![]() ![]() This image was captured to check ignition spark trigger event relative to TDC at 2000 rpm to verify PCM spark advance command. I'm assuming spark is happening on the falling edge? It looks retarded? I found it strange that cam/crank are using cylinder 3 at TDC...
