Ok, so we got talking about O2 windows and then started hijacking another thread! :D

New thread time!

I found 4 tables for O2 windows:

Closed Loop @ 0x48F5
Open Loop @ 0x48F7
Closed Loop Idle @ 0x48F9
Open Loop Idle @ 48FB

The limits are all DIFFERENT! Some, not by much, however. The upper limits range from 677mV to 734 mV. The lower limits are from 278mV to 352 mV.

How much should I tighten them up to? Or, in what increments do you suggest I change them? I, too, think that swinging the AFR up and down is pretty silly. Seems like the motor would be happier with a constant AFR, not something that's zigzagging all over the place.

Thank you!
