Fast vs Slow O2 thresholds?

On the 7730 ECM in CATS

There's some O2 tables entitled:

Fast O2 Rich/Lean Threshold vs MAP
Lower zero error reference for slow O2 R/L vs MAP
Upper zero error reference for slow O2 R/L vs MAP

I read through the stickes on O2 stuff, but I couldn't find the answer to tihs...

Thanks.

Re: Fast vs Slow O2 thresholds?

I believe it is just the filtering if it is heavily filtered (Slow) or very little filter for "fast" response. Reading is filtered differently for some calcs.
That's off the top of my head, I'll wait for Rbob to let me know if I'm all wet on that one.
