[QUOTE="03cobra#2, post: 16519256, member: 52057"] Idle don't look too bad. Couple things. After a couple minutes it looks like your af stabilizes around the 12.5-13 range. Im not sure how to decipher the maf counts as on my logs it's called maf ad counts. When looking at maf ad counts it reads the number that corresponds on the maf transfer table. Anyway, I would subtract a bit of fuel from your maf table at idle. Maybe take 3-5% away and see how it does. I really don't see your AF swinging all over the place. Again after a couple minutes of warm idle af is steady. Couple other things. Once you get af closer to 14-15 at a warm stable idle your idle air integrator needs a bit of work. It is reading -.35. It should be closer to 0. A quick Google search will say how to correct that. After those parameters are good you can try lowering idle spark..... If idle seems a bit rough and / or won't settle down to 800. [/QUOTE]
