Is GM.MFTOTAL the total count of misfires on all cylinders...?
When does it reset back to zero...?

As best I can tell... Yes. It should reset after 30-45 seconds of no misfires.

So if it stays at zero all the time then it means I'm getting no misfires, am I correct in saying that...?

Thanks,

Also, what does GM.MFCSTAT do...?

Thanks again :cheers:

If you're reporting 0 misfires then you're either not getting any, or it is disabled in the misfire section of the Engine Diagnostics {C5601+} which is the case of a lot of tunes coming from one of the mail order guys.

As for MFCSTAT, I've never logged it to see. :nixweiss:

GM.MFTOTAL is zero, and my tune has misfires enabled (stock settings, I didn't mess with those, no mail order tunes);

I do have new plugs and low ohm plug wires...
