I've never had an issue with running with it off, as I did when my tps signal went wacko. Wouldn't keep it like that, but it's shouldn't be as jerky as a over reacting AE.
So question for you AE masters. I try to tune the lean spots down with AE, but the little graph below the chart shows a rich spike too. The more I tune out the lean spike, the bigger the rich spike gets.

I'm with Vlad. Sounds like your overall fuel tune (VE map) is lousy. I'd disable AE and work on that first. If you're well-tuned, you should need almost no AE at high RPM and just a bit at low RPM to get over off-idle flat spots.
I'll bet you're super-lean off-idle.
Are you using TPS-based or MAP-based AE? If MAP-based, be aware that MAP sensor noise can trigger an AE event. Use TPS-based if you can.

I am using 100% tps.
Yeah, that's what I'm leaning towards as well. I never really worked on my VE map. (been using the one rev supplied).
I was reading a few other posts, but I wasn't aware that I should have really dialed in my VE map first.
However, I would still like some explanations on AE. I truthfully don't know what the hell I'm doing. To my understanding, TPS Dot is the rate of change (based on time). So if I adjust that, it causes me to go way lean, then way rich, and if I adjust the TPSdot to a larger number, it causes it to go way rich, then it'll clean up.

All right. I've got the VE map dialed in pretty good.
I took my TPSDOT and turned it up to 1000 or something crazy to keep it from activating.
Now when I shift, it goes lean then comes back. It's really annoying when I'm trying to take off since it goes lean, and wants to bog.
So, should I now work on my AE? I feel like I've got my VE tuned well enough.

the whole point of AE is to remove those lean spikes when you apply heavy throttle to increase smoothidity[sic]*.
EAE takes it further and keeps AFRs stable during slower manipulations of the pedal.
