RE: Nightrider O2 IEDs, Field Test
That's been one of my big questions with these. That being what happens when the closed loop bias is higher than anything the ecm will ever see with the ied's. Does it give up, say the sensor is failing and revert to the fuel table? Does it go to max duty cycle on the injector? Does it hit a limit on how much an adjustment it will make and stop?

But that question remains whether we run IEDs or not. Its been noted that setting the code as historical may be due to O2 polling frequency ie it apprears as a transient failure due to reversion or leakage. People who buy these dont care. If you do, buy a tuner. Its a fast cheap mod.

That is exactly what happens when the o2s get old and lathargic. \\;You will get a CEL when the ECU \\;can no longer see voltages above .5 \\;even after bumping the o2 correction and/or the AFV to the rails. \\;

Yes, you do. Again, all-stock or all-H-D stage 1, and the regular IEDs (not X) wouldn't be bad. Any other setup, any at all, and they're just further dice-rolling.

Glen, You have no idea if the 02 bias tables are still set to .45 +/- in the Stage 1 stuff without data loging it.
