Not sure it matters. OP's equation is calculating correctly in live link II. At 1.67 volt it should be and is at 13.4 afr. Boils down to why the output voltage of the wideband does not correlate with the display using the given voltage. Was there a way that you could have adjusted, programmed, the span of the wideband? So that the equation would need to be changed? From the manual I downloaded, it states that the analog output voltage is 0-5 volts. And a span of 10. So, 0 volts would be 10 afr and 5 volts would be 20. When I have my wideband powered, but the engine off, never started, my gauge is pegged at 20. As well as my voltage, but at 4 volts not 5. Since my output voltage is 0-4 for my wideband. Did you buy the wide band new? Who installed it?

Sorry to hear that I was looking forward to finishing up your tune all I need is to check AFR at Wot and Log the runs on the dyno or on the track.

I will be happy to work with your local tuner as well.
