narrow band autometer gauge

[one92rs]

i got an autometer narrowband air fuel gauge. it seems to jump aroun d more than i thought it would. the gauge is good. now for my question. could it jump around due to me having a heated 4 wire 02 sensor instead of a single wire 02 sensor. i know the signal is suppose to be the same. but!! would the newer 4 wire 02 sensor read faster than the older single wire 02 sensor causing the gauge to fluctuate so much.

the reading will fluctuate a LOT in closed loop.

Yeah I think I've seen them with the LED lights? They work well on a narrow band O2 sensor by itself for like tuning a carb. But when hooked up to the NB on an EFI system you get to see the cross counts.

so would it settle down with a regular one wire 02 sensor verse the 4 wire 02 sensor?

[EagleMark]

Not if it's still hooked up to the ECM in closed loop. In closed loop the ECM keeps cross counts going back and forth across stoich.

Unless there's another way to wire it?

not that i'm saying it's a good idea, but a resistor/capacitor combo would essentially average out the signal and make the swingin much less noticable.

response time to new conditions would suffer though.
