ok iv been poking around with my Idle I think I have that setup now im trying to get my fuel dialed in from my last log they said i was running rich ...well id doesn't seem to run rich? car runs really good all they way up to 5400 rpms then i get some knock im not sure if its from running rich or if i need to adjust some more timing,

A: How do you tell (from this log) if its running rich

B: is timing needed? MAF is flat does need adjusted?

C: also iv noticed at full throttle it says 94%???

thanks

here is the log cruise in 5th then 4th the 3 gear pull

You're definitely on the richer side. Your AFRatioEst is reading 9.5:1. Your next mod for your car should be a wideband o2 sensor so that you can effectively tune for an actual AFR (the AFRatioEst is not accurate enough).

You should actually go pull a couple degrees of timing where the knock starts. This will help keep it from knocking. So if you see 1 count of knock, pull 1* of timing at that RPM. With 2 counts of knock, pull 2* of timing, etc.

You could safely pull out a bit of fuel to lean it out. I'd say shoot to have your AFRatioEst around 10:1.

Awesome so as far as the fuel goes do i just lower all the tables?

ok here a fresh tune from today

i lowered the fuel tables and timing results are,

more knock around the 5750 to 6000 rpm but no more knock around around 5300 5500 rpm so....lower timing again? the 6000 to 6500 area? "smooth it out" so to speak?

also how is the fuel looking?

refined tune of today i have most of the knock gone.... still not to sure about fuel should I try to tune out the small amount of knock ?
