copy pasted from clevelandracing.com, how do i add files to a post!??

here's a log i posted before, 18psi, very little changed from whatever ecmlink sets the basetunes up for, this is around a month ago, setup hasnt changed a bit in the bay, clipped log 2 is from last night, and it was on an entrance ramp fwiw. 23ish psi, showing acceptable knock(this sensor is super sensitive and noisy) and a significant increase is gm/sec, im hitting 37lbs/min, no idea if going uphill hurt or helped that number. lotspot jerry had done a tune but i didnt care for that so these are both my work. i guess im looking for opinions and tips on getting more out of it as is, even though its kinda pointless at this point in the season. just trying to learn ha.

edit:
i think i need more mafcomp work, despite commanded afrs remaining in the mid10s' there a part of my rpms that consistantly goes a bit leaner, which makes me feel nervous about leaning it out.

I always just added fuel to that rpm range then changed the global settings to my liking.

Are you on the ECMLink forums? I will take a look if you have the logs linked up.

srsly, 10 peeps told me this after i posted it on cr. taking it there. i guess i can pm you the logs or mail them to you if you're curious or wanna gimme a tip.

I would assume you are wanting tips or suggestions how to improve your tune as you posted a question about it on this forum. Without knowing a few things about your build and current tune I can't provide either.

I can tell you that rich knock happens when you are below 11:1 AFR. You probably need to back the timing off then get your AFR stable around 12:1. ECMLink has a few pre-built tunes that include Timing and Target AFR tables that are good starting points. If you feel that your MAFComp isn't good then tweak that until you are happy with it. I have played the MAFComp game with a 3" GM MAF and will never do so again since Speed Density is cheap and very easy to tune with.
