FTC values = x??? what's x ???
I know the various fuel trim cells are active under different conditions (open loop, closed loop, a/c on, a/c off, in park in gear, etc...) but what do the numbers mean?
If I want to tune my car so the LTRIMS zero out or go negative... which FTCs should I be watching?
