I am using the aem uego wideband. The attachment is what I got when I scanned for my lambda error. I have watched the greg banish video many times and he is always trying to get to 1 and mine is way up in the teens. What do I do to my VE table to edit my tune. I have some areas up near 20 so how do I get that back down to the 13-14 area? Any help is appreciated.

What you're getting confused is that Greg is working in terms of Lambda, not AFR. I actually switched to using lambda a while ago, and find it easier myself.

Is there a formula to give me lambda? Or how can I figure out how to edit my table with these numbers?

I am pretty sure I am over thinking things and have read to much online. I have a few formulas made up for Lambda err and was hoping someone could tell me if any are correct. Also what should I have under the units dropdown?

Legend
Commanded Lambda=[PID.6001]/14.7
[PID.6001]=Air Fuel Ratio Commanded Hi Res
[AUX.20005]=Wideband 02 AEM
[USER.9004]=commanded Lambda
[SENS.121]=Air Fuel Ration Commanded

These are the 3 error formulas I have come up with.
1. [AUX.20005]/[USER.9004] - last scan at end said 15.99 Lambda in table display
2. 100*([AUX.20005]-[SENS.121])/[SENS.121]- last scan said 8.75 in table display
3. [AUX.20005]/14.7- last scan said 1.08% in table display

Not sure if you solved this or not but if you look at the scanner you are recording Commanded Lambda which is correct but your AEM gauge is reading AFR and throughing your corrections off. You have to switch the EIO input settings to read Lambda for your gauge. The gauge will still show AFR but HP scanner will show Lambda.
