Wideband question

[Blakonblak94]

Ok, I will preface this by stating my wideband issue isnt occurring on an SVT car, however most people here are intellegent and helpful. My LC1 is reading dead lean on the gauge and output wire. I have tried adjusting the MAF transfer in the tune to get it to read rich as hell, and tried a spare sensor I had on hand. My only thought is that the cold is making it act ugly, which doesn't make sense to me, but is the only reason I can fathom other than a hardware issue. Any thoughts?

Are you just starting this tune or is it one that's been in use for a while? It is possible to have an A/F so rich that the sensor reads it as lean. It has to do with the amount of oxygen in the unburned fuel. Try taking the A/F the other way and see what happens.

Oh sorry I didn't clarify, this was a previously working tune. I will try pulling fuel. It doesnt deviate if im in nuetral and rev the motor slightly either.

Update: it appears it could be a controller issue. Wilp report back
