Alan, what is the story on the new one? And what wideband do you all suggest? Stock VW Golf? Ill be buying one shortly. Thanks .
To BPSX's credit, he sent me free of charge a complete unit, pre connected, pre calibrated, pre wired, All I had to do was hook up power and ground.
The result of this, the 3rd unit, is the same as the 2 previous units; with 11.78 AFR gas, the unit reads max rich 7.xx . I scope the signals and the unit electrically behaves all over the place like the other 2 units.
I did not want to beat a dead horse, so I did not post my result until someone (you) asked for it.
