lc2 value vs. factory wideband

[hereinmissoula]

When my logs show 13.5, wideband says approx 14-13.9. About a half a point off.

I am assuming I should trust the innovative and ignore the factory o2?

Just tune the car to 12.5 (on factory sensor) to get at true 13???


Thank you

Are you comparing values by datalogging or the innovative gauge?
At stoichiometric (lambda 1.0, AFR 14.7:1), what readings do you see? The reason is that any o2 sensor is accurate right at lambda 1.0, so if you see a difference then it is one or the other o2 sensors or innovative voltage output. My experience of the innovative is that it would randomly change the voltage output parameters and I'd need to reprogram these every week or two, but if you're comparing gauge to datalogging this probably is not the problem.

So if they are the same at idle and my voltage values are correct for lc2, which sensor should I follow...??.?

Think I have the 0v-7.35 afr 5v-22.39




This is comparing the logged factory O2 comparing to innovative gauge and O2.


I'm about to start spraying so this will be important. Starting with 35 going to 80 shot.

Side question, what is safeish rpm to spray to??? I was thinking 8000-8300 or so rpm limit at 8600

I'd trust the LC2 over the factory o2, but we had this happen on our own cars and ended up putting in an additional o2 sensor of a different brand to make sure.
I only ever rev stock K20 engines to 8300 rpm.

Thank you very much!!! :)
