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!
Safe A/F ratios for MAP calibrations?

Re: Safe AFRs
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.
