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
