General What Fuel trims for 2G

[Vinnie]

Anyone know what the high, medium, and low fuel trims should be for a 2g car?????????

Optimally you want to see trims at or near 0.

PaleDSM is right, as close to 0 as you can get (+/-3).
2G's only have two though; long term and short term.

I've managed to get the short term setup to -\+ 0.
But how do you get the long term to change, mine's around +10.

LTFT's are based off of STFT's. If over a period of time the LT's are not moving closer to the ST's/not moving at all, reset your ECU.
