correct. stock 02 sensor not designed as such.

All Right, I guess cheap bums like me need to bite the bullet and get a
WB o2 monitor. This is another case were switching o2 monitoring just
doesn't cut it, am I right?

i would suggest that TPS AE is immediate and possibly less
duration as far as time on. MAP AE is possibly longer in duration and
dependent in the MAP sensor "seeing" the need. i assumed for one season
i had inadequate AE or PS as i was bogging. i thought my mods allowed
me to flow air easier than fuel so i upped AE. I went too far. i
discovered with a WB installed. i was off the scale at 8.0/1. i
removed considerable from AE tables and it is so much better. need to
fine tune AE this spring. AE is difficult to tune IMO as it will not
show in scanning.

Ok, I figured out my PE bog. Turns out the guy who had
practically every table set wrong had the spark table way wrong.
Anywhere from 3 - 15 degrees. As far as AE, there is AE Vs MAP and AE Vs
TPS, I understand that this is a calculated 'pump shot' based on TPS or
MAP input. What I don't get is why you need both. Is one for 'off the
line' and the other for sudden stabs while cruising? Do the tables add
together? Hope someone can give a good detailed answer. The reason I ask
is that I have a nasty hesitation off the line, but only when the
outside temp is below 60 deg F and I'm in CL. I'm assuming that one of
these tables is too low such that with the denser air it's too lean.
Thanks, Ski
