im following the VVE tuning guide and am applying the changes to b8101 and the AFR's will not move from 11.6
i dont have any problems flashing the map and it seems like the changes i make are not being applied. Can someone please help?
urgent help needed please

Did you fail the MAF, a DTC must show up immediately on engine start.
Did you generate coeffs...?
Try pasting to the other 1-bar VVE tables also, and generate their coeffs.
Did you disable CL and any/all forms of fuel trimming (LTFT, STFT, and any others if they exist, e.g. STFT on OL stoich)...?
Is your wideband producing correct/sane lambda measurements...?
Is the ECM saying correct/sane commanded lambda, does it agree wjth the acgive fuing table (i.e. OL or PE)...?

Are you logging SAE.LAMBDA...? Try this instead of AFR.
EDIT: I can now look at your log in post #1, and I see that you are logging SAE.LAMBDA.

What are you using for BEN pid...?
It should calculate {EXT.WO2LAM1}/{SAE.LAMBDA}

able to log and I copied table with labels over to those 4 parameters on VVE and did a paste with multiply, generated vve, then coefficients, and it just seemed to run even worse.
I have no idea what the problems was. it turned out to be a mess with my buddy having to get a two truck home because we simply ran out of time and we have to work tomorrow. I kept making changes and flashing but the AFR's didnt move. Today was very frustrating but I thank you Joe for helping me out.
Post the latest tune and log files here.
From the log in post #1 it looks like your wideband is not working properly.
Oh man... Well I'll post it tomorrow. I'm really trying to work out the idle. I can't drive it anywhere without stalling, and it has a hard time running period. Can I just multiply the whole vve table by 0.7 to get it to run leaner if my current lambda eqr is 1.3 off?
You can try multiplying the whole VVE by 0.77 (i.e. 1/1.3) and see how it goes...Originally Posted by lsx_production
