I have installed my Innovative wide band using a techedge display. Anyway I notice that my cruise afr's move around very quickly all the time. It seems to cycle through normally going from 13-15's very quickly changing. Sometimes seeing even higher around 17's then back to 13's. At idle, part throttle through wot it seems to stay steady. Has anyone else seen this. Also could this be from the oem sensor going bad?

Thanks

 

Is this just due to the 02 sensors feedback loop? Does this mean my oem sensor is going bad and the values are slow since I can see them change? Due most just average these changes to produce a clean AFR value?

 

Sounds like a fairly normal operating o2 sensor to me.

 

Should I be worried about it spiking to 17's on occasion? That's what I'm worried about whether others saw the same thing or not.

 

All cars running under closed-loop could do that -- in vacuum. There really is no danger to the motor.

If you don't like it, disable the o2 and tune all your vacuum cells how you want them to be and then they will be stable.

 

Thanks

 

I wouldnt worry about it. My car see's mid to high 15 afr's under 45+kpa of vacume. I tuned for that, and the car likes it
