Guys isn't CALC.EQBEN_LS1 same as CALC.WO2BEN since they use the same expression factor = {GM.EQIVRATIO}*{EXT.WO2LAM1} ?

Never got my VE dialed right, also used CalcVet & CalcMaft with no luck either so returned back using AutoVE.

I also suspect that there is something wrong with the Lm-2, I get crazy AFR swings jumping all around from 11-16 AFR.

Vehicle is a 2003 Sierra w/LS1, 215/223 -112LSA and stock lq9 heads with truck manifold. Stock file and used only Spark tables from an Ls1 file.

Thanks,

Jay.
