I raised the numbers on my ve table but it don't seem to do much to my afr. I have a lc-1 and it says my afr is 16 t0 1 ish. When I add fuel with the bidirectional the motor likes it and the afr drops but the it gets really rich at low rpm. I'm working on a 99 trans-am the I just put a 402 w/stage 3 patriots and a 224 cam. What am I missing or should be doing?

Light throttle it's in closed loop and running on the LTF trims.

The object is to get the actual AFR to match the Commanded AFR.

The VE table is doing almost nothing with a maf.
You need to play with the maf calibration. table B5001.

If you go to far it will throw a dtc relating to maf map comparison or similar.

Do a search there is a post with a how to and some maps so you can autotune the maf.

Works wonderfully
