My tune keeps changing
Posted: Sat Aug 22, 2015 2:52 pm
99 4 door civic with a3 swap, been running good for the last month but lately my tune keep changing up on me often enough that I have to carry the laptop to tweak it like every day. Example 5am I leave home for work, idle afr 11 so i get up to mid 14's, then 2:30 I get off I fire her up afr's like 18, then driving home she suddenly goes lean, like way lean that i had to pull over cause she would barely move. I'm not sure what the problem is maybe a bad sensor or something. So feel free to throw ideas around, need my baby to run good again lol.
