AEM Wideband AFR Calc? - Camaro5 Chevy Camaro Forum / Camaro ZL1, SS and V6 Forums

I just hooked up wideband in my car, but the signal to LiveLink is sending a voltage reading. I can't seem to find any equations to convert it, but reverse calculating it from the grid in the AEM install instructions looks like this:

Volts AFR
0 10
.16 10.32
.31 10.62

So I'm gathering the caluc to put into livelink is (volts x 2)+10?

Does that sound right?

That is correct.
