Misfire count, knock retard. How much is too much? So I've been playing around with an OBD logger, torque app http://torque-bhp.com/
And noticed after a few runs that cylinder 7 and 8 had a misfire count of 2-3 while cylinders 1-6 were fine. Additionally I pulled .04 of knock retard.
5.7 LS1 with 50K on the clock
Just curious what kinds of thresholds I should be looking for on the knock retard and cylinder misfire count.
Thanks guys

All those are more than ok, nothing to worry about.
If you had 1+ degrees of knock you might want to fix it. If you had more than a handful of missfires you might want to fix it.
But sometimes even well tuned engines have a missfire here and there or a slight spark knock.
