my front Low fuel trim is at +12.5%, and my rear low fuel trim is at -12.1%.
um, LOL.
*throws in the towel*
i can supply a log but this forum doesnt allow .csv files to be uploaded.
not sure what to do. if i increase the fuel, it'll fix one bank but make the other worse. and visa-versa.
the weird part is that it seems to idle just fine at 14.7.
where the heck do i even start with that?

FPR over run. It does that to your trims.

oh good, its not just me. lol
i need to figure this out asap. need to get the car tuned today. i change fuel and reflash, but its not changing the fuel trims
What do you mean by this exactly? You're changing the fuel table?
I always assumed this happened in my car due to FPR over run, but it appears that's not the case with all you guys.
Also, it takes 16min for the long term trims to update. Make sure you're changing the MAF comp values with-in the correct HZ range of the trim you're trying to adjust.
