What I thought was a cheap no markings "just splice in" muffler shop O2 sensor was actually a Bosch O2 sensor installed. Bought the correct NTK sensor from Amazon and it indeed is an exact plug and play match for Regina systems.

Voltages: Bosch: switching from near zero to .780V.

NTK: Switching from near zero to 1.025V Maybe a tad more at times. Should I not have a max of 1.2V like the faq states?

Apparently the ECM can be fooled by a Bosch sensor installed. Although I would like to think the actual proper mixture should have been leaner.

Mileage. Tank filled until nozzle clicked off, then I coaxed another 2/3 gallon more ( I prepaid and was lazy to go back in) I went 267 miles until the needle was about 1/8 inch from the red mark. I estimate I put in 16.5 gallons so guessing how much further I could go my figures come to about 20 to 21 MPG.
No warmup time and temps in 65-70F range. Kinda disapointing but I plane to do a more accurate estimate later. Seems to idle a tad smoother, altough sometimes I could barely feel it run in drive.
