Tuning MAF in Open Loop ?
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. |

I don't know if this is relevant but when I was at Performance Motorsports they told me that they don't mess with the idle tune... it is always rich and irrelevant I guess.
What are you really going to gain? |

but even in Open loop with my wideband still see some fluctuation of about half of what I was getting.. to answer your question ; Im trying to get a more stable MAF tune because my whole CAI is custom made. (maf tube included) dealing with te K-fuel / MAF table isnt an easy job. at first I thought my K-fuel wasnt alright , which seemed to be one of the problem .I still suspect my OEM AFR wideband to get sluggish from the finding I have done ... |
