high like the title says my AFR is high. well i think its high when im driving its at 14.5 to 14.9 depending on how im mashing on the peddle. i recently had my engine rebuilt and i have the mods listed in my sig. My AFR is the same with the Power FC and the stock ECU> I was just wondering if there was any functions on the power fc that i could try. I have tried to raise my injector up but the AFR stays the same. i am just seeing the AFR through my apexi turbo timer that has an AFR option that may just not be working but any help from you guys would be great thanks guys.

what do you mean by mashing it? those readings are a bit OK, for cruising steady. you should take it to local rotary tuner and see if they can figure it out and do a tune. if you dont feel comfortable with the PFC then i wouldnt try fixing it. expecially when you dont know what settings affects what

The AFR reading from your turbo timer IS COMPLETELY USELESS at anything other than cruise conditions. Cruising, it should be around 14.5 (should bounce between 14-15).

Get a real wideband with a 4 or 5 wire o2 sensor if you're worried about it.

And then if you see 14.5 while boosting, you're in danger.

yea 14.5 under WOT would be a bad thing
