for those of you who has the experience in tuning.

I'm trying to fine tune the MAF at idle/cruising

Would it be better to tune the MAF in Open loop ?
because right now my AFR fluctuate from 14 to 15 Afr at idle and the compensation are within 95-105 ..

I have read that the O2 sensor should do that in 1 sec but mine takes 3.7 sec from peak to peak .

so now I'm guessing my OEM 02 Sensor are getting too slow ?!?!

disregard the LC1 log at 20.8afr , I just installed everything with the LC1 and computer to make sure everything work and log correctly.
