Green wire from under dash.I see in your pic you have a wire going to the MAP input, but there is no MAP reading in powerlogger. Where does that wire go?

The White analog output goes to the PL.The stock O2 looks more normal now. According to it, it's on the lean side. What are your current axis settings, like in the picture you posted? We can make some adjustments in there.
The wideband is not right. You'll need to ignore that reading for now until we figure it out. Still need to know where the black ground wire goes, the white analog output, and the brown analog ground.
I would put a new IAC in it, or inspect the passageways and make sure it all looks good. It's still erratic.
OkI would try grounding the black wire to the engine, and also moving the brown analog ground to #4 ground on the powerlogger input board. I would do the brown wire first, as that might fix it up.
Ok, if the volts are low from the map, how do I change that?Glad you found something. The wideband reading is still not right. I would see if the wideband gauge is matching the powerlogger reading. If they match, then I would be tempted to replace the wideband O2.
Also, the MAP reading is showing 3" of vac even with the engine not running, so that reading won't be right either. I see the volts are low from the MAP, should be around 1.5 or so, engine off, yours is about 1.4v.
