See the enlarged and bolded text for your reason why it didn't swing. ;)
The O2 does not require power to work, unless there is a heater element. The O2 sensor creates it's own signal voltage. To use a NB gauge, all you would have to do is connect the gauge as normal, and connect the signal wire directly to the O2, no extra circuits needed.Quote:
So you got the gauge, was there any info on how to get a NB O2 sensor powered for gauge without ECM? Depending on ECM I have seen some stop cross counts in certain situations. Like my LT1 in WOT I get steady o2 readings from each side. No cross counts...
