There's so much that can go wrong with WB, mostly do to grounds of EFI system and grounds of WB. But can also include reading to gauge which is same if you use serial port but differant if you use AD1 or AD2.

That is why I said originally I make three values, 1. WB AFR, 2. WB Volts, 3 WB Lambda. All three have to match, then match my gauge as well... if the three to ECM/PCM match and my gauge is still off it's usually a ground. Gauge grounds through WB, AD uses ECM/PCM.

I've seen in instructions for Innovate products that there are several new versions on the LM Programmer, but still the website has the old version to download. Which version do you have? I'm still on 3.32, but 3.29 looks to be easier to set up.
