Safe A/F ratios for MAP calibrations?

Post by k20z3kid »

Hey guys. I have been trying to find an answer by browsing around different forums but I have been unsuccessful so far.

I have an 06 Civic Si with a AEM V2 cold air intake. I recently switched to the MAP calibration for this intake. I am unsure of what is a safe AF ratio. With regular driving I am roaming around 14.7 ish and I know that is fine. But I datalogged a 3rd gear pull up to redline at WOT and from 5500rpm to 8200rpm my AF ratio fluctuates from 12.5 - 13.3ish. Is this safe? Or am I causing damage? Thanks Hondata!

Awesome. Well that is good to know. What would be the safe area for AF ratios? How low and how high can the AF go without doing damage? I am guessing there is no really a straightforward answer to such. lol.

At WOT you would want it between 12.8 - 13.2 with it tapering off to 12.8 in the upper RPMs for added safety.

At part throttle between 14.5 - 15.0, those AFRs would be for columns 1-7.
