[805eclipse]

i logged my car today with my datalogger and laptop and i looked at the fuel trims and they dont move there just stuck at the very top what could cause the fuel trims to be stuck??

I've got the same deal...like 85% low trim...99.2% mid trim...and 81% high trim. Stays constant the whole log. Can anybody tell me what that means? I don't quite understand yet

and regarding fuel trims being stuck...are you sure you dont have a "pause" box enabled. i know on my palm with mmcd sometimes i think its broken because the pause button is enabled...

read the explanation and you will understand them.

they are long term, meaning they dont really move, unless you drive the car differently, in different weather or other conditions exist.
