culled from this waveform set

we have this , a zoomed in view

overlayed in there is a few 720 degrees running compression waveform so the eyes can see where the exhaust valve opens
so it can be seen that cylinder 2 is exhausting a very rich puff
this is a TBI engine .

the spark waveforms all show , LEAN Condition - and
LONG TERM FUEL TRIM is SUBTRACTING fuel

do not use diesel in your gas - it will NOT enhance anything .
