With that in mind a wide range of values could be safe or unsafe. Make sure the maf is nicely seated.

Cobb af learning 1. Corrections start as a multiple of 14 and are learned away in increments of 35. Still i continued my commute 95 miles approx one way hoping that it will correct or go. Af learning 1 should be 8. Something is leaking air between the mass air flow sensor and the engine. Fine knock learning sometimes abbreviated fkl is a learned correction that the ecu uses to make tweaks to timing. I am just getting a little worried because i know you dont want to exceed a 8 on your af learning 1.
I am aware that cobb suggests up to 8 for the third gear pull to redline but what about under other circumstances. If you only installed the intake go back and check all of those fittings for leaks. If fkl hits extreme values the ecu will consider modifying the dam. Its thats pretty close for just cruising speeds. For example i was cruising the other day at 7580mph and i would hit up to 11 for af learning 1 during normal hills and traffic flow. In any case the ecu adding fuel means a lean burn which implies an unmetered air leak.
First time since i installed a cobb stage 1 its been 2 months ago. Af learning 1 a was 59 varied from 59 to 51 af learning 1 b was 80 af learning 1 c was 66 af learning 1 d was 87 dam was 1 yesterday i checked them again and the values were af learning 1 a was 53 af learning 1 b was 70 af learning 1 c was 64 af learning 1 d was 95. Actual afr will vary greatly depending on the conditions the engine is operating under. Cobb stage 2 af learning 1 issue submitted 1 year ago by ktryan30 just installed a grimmspeed catted jpipe on a 2017 wrx everything is looking good except im getting a af learning 1 reading of 11 when my car is idling stop signs and red lights then it calms down to 7 when after a second or two. Yes the ecu is flashed with ots cobb 93 oct stage 1 sf.
