2004 Stage 2 WRX AFR Question
Hello, I've noticed recently that on my AP my AFR boosts up to about 22-23 and doesn't really go any lower than 14. I've read that the AFR is supposed to get richer while accelerating, not leaner. I believe I'm running the right map, I have a TBE, Cobb Short Ram, and the v3 AP. I'm concerned this is a problem and can any of you help me out? Thanks.

Which map are you running? Have you performed any troubleshooting?

Get a wideband and/or have the car dyno tuned.

What are your AF Learning and Correct, etc doing when you get the high AFR and when does the AFR issue occur? (idle, cruise, wot, etc..)

Is the AF Learning and Correct a gauge on the AP? I haven't used that one. The issue occurs when under decent acceleration/WOT. At idle and cruise the level stays around 14.7
