Hope it's ok if I ask another AEM related question in this thread.
I'l start with a short introduction about myself. Engineer in Digital Video Broadcast, but with a good understanding of electronics in general. Have recently bought my first EFI Live and are about connecting it to a 03 Silverado 1500 5.3 That I'm mounting a Edelbrock e-force supercharger to. Just finished welding a extra bunge in the kooks header for the AEM 30-4110. Can I use the calc_pids for my setup?
This is how voltage output correlates to AFR/Lambda.

I am hooking up to the same gauge. I sent my V2 off to socal diesel and it got updated and now I see the ad1 voltage showing on the V2, but I can't get it to display the W02 on the V2.
Thanks so much for any and all help guys!!!

Well , as per usual I wait so long in between sessions I am lost as a newbie. I was viewing the wide band on the V2 and logging it months ago before the upgrade to the new version. Help me get back on top of it please sir. I see the voltage on ad1 when I do the self test so the V2 is seeing the voltage variations.

The fail safe gauge is analog only. I have a thread where I set it up originally and it worked fine for a good while.

From the AEM data you posted:
AFR 10 --> 0V --> lambda 0.683
AFR 19.98 --> 4.99V --> lambda 1.365
Find AFR as a function of V:
(AFR-10)/(V-0) = (19.98-10)/(4.99-0) = 2
AFR = V*2+10
This is the same as CALC.AFR_PLX1, so you can use that pid... but the corresponding BEN pid CALC.BEN_PLX1 uses GM.AFR instead of GM.EQIVRATIO...
so if you wanted to use GM.EQIVRATIO (which I would recommend), follow along (you already know algebra):
0V --> lambda 0.683
4.99V --> lambda 1.365
Find lambda as function of V:
(lambda-0.683)/(V-0) = (1.365-0.683)/(4.99-0) = 0.1367
lambda = V*0.1367+0.683
We now want to find the assumed stoich AFR...
Solve V for lambda = 1:
1 = V*0.1367+0.683
V = (1-0.683)/0.1367 = 2.319V
Find AFR for lambda = 1 (i.e. for V = 2.319V):
AFR = 2.319*2+10 = 14.638
so AEM device assumes stoich to be 14.638.
So now modify CLC-00-030 from the above calc_pids.txt to read as follows:
Code:*CLC-00-030 AFR 8.0 18.0 .2 "{EXT.AD1}*2+10" LAM 0.5 1.5 .3 "{CALC.AEM1.AFR}/14.638" EQR 0.5 1.5 .3 "1/{CALC.AEM1.LAM}" BEN 0.5 1.5 .3 "{CALC.AEM1.LAM}*{GM.EQIVRATIO}"
