Alright,I recently dynoed my car a couple of days ago, and I wanted to know about my A/F Ratio. I t says on the sheet MAX air/fuel= 17.5, but I dont see 17.5 on the dyno chart. I want to know if it is running to LEAN, mods are B16A SIR2 i,h,e skunk2 P28 ecu. #'s are 3000 rpm= 13.5 a/f, 4000 rpm= 12.5 a/f, 5000 rpm= 13 a/f, 6000-8000 rpm is 14.5 to 13.5 a/f, is this GOOD or BAD. Thanks

 

thats probably when the guy let off at the end or soemthing, and the dyno is still recording, so dont worry too much.

 

So ur saying when he let off the gas at the end of the dyno? Because on the sheet it shows from 7000-8000 prm is 14.5 to 14.0 A/F.
