SAE.LAMBDA should work.
The E38.AFRATIO_DMA works as that is the one I was currently using. The SAE.LAMBDA if iirc it said it wasn't valid with my car and didn't work at all. I thought I tried the GM.EQIVRATIO too and same thing.
I read the afx manual and the afrm manual today and that's why I say the afrm is misleading. The afx says the display stoich is 14.57 and they use that in there example for lambda aswell. The afrm says the display is 14.7 but yet for lambda they say 14.55 is stoich so Im not sure which one it is. Like I said on the excel program for the voltage offset expression to match the B3601 the formula they provide, b3601 comes out to 14.7. 14.55 is different
Here is a log and tune and pid list if that helps
I see E38.AFRATIO_DMA...
Were you able to log SAE.LAMBDA at all...?
If SAE.LAMBDA does not work, then you have to edit calc_pids.txt as follows:
Code:*CLC-00-003 V 0.0 5.0 .1 "{EXT.AD1}" AFR 8.0 18.0 .3 "{CALC.NTK1.V}*2.75+7.625" LAM .5 1.5 .4 "{CALC.NTK1.AFR}/14.55" BEN .5 1.5 .4 "{CALC.NTK1.AFR}/{E38.AFRATIO_DMA}" *CLC-00-004 V 0.0 5.0 .1 "{EXT.AD2}" AFR 8.0 18.0 .3 "{CALC.NTK2.V}*2.75+7.625" LAM .5 1.5 .4 "{CALC.NTK2.AFR}/14.55" BEN .5 1.5 .4 "{CALC.NTK2.AFR}/{E38.AFRATIO_DMA}"
EDIT: THE NTK USER MANUAL IS WRONG, IT SHOULD USE 14.7 AS STOICH
( THEREFORE USE 14.7 INSTEAD OF 14.55 IN YOUR CALC PIDS )
The calc_pids.txt file should be edited accordingly.

I have to multiply the lambda by 14.2 than divided the commanded afr though right so the ben factor would be correct if that's what the stoich in the tune is set too? Im going to call ntk this week and find out what stoich is exactly with this model.
I need to set the stoich in the tune to 14.2 first.
Try to get SAE.LAMBDA to work
Otherwise use the AFRS for the ben factor?
