You can't see the injector pulsewidths snap from 0 to 16, over and over again?
Sine wave is smooth, what you've got there is sawtooth. I am not surprised it doesn't feel pretty. I don't know what causes it, because if it were RPM or Boost cut It'd have no reason to continue hitting like it does.
I've found my car likes to spike lean, then fall still 1/2-1 point lean of target on a heavy AE hit. If I give it enough to spike lean, then fall at or richer than target it looses a good bit of go. I assume I am flooding it then, and that doesn't make good power. It's impossible to loose the initial lean spike, at least with a tpsdot PW adder like this.
You seem to be near or around even to target after AE, but your wideband placement, sensor, or whatever else might make your car like something different than mine.
That's about all the advice I can give, truth is I don't really know what all I'm doing either and I don't like to mislead.

I captured what I believe to be 2 separate instances of the saw tooth PW and duty cycle. That's causing my stumbling in first, and my stuttering, flat spotting whatever you want to call it in all other conditions.
Is it time for new injectors? I bought refurb rebuilt RX8 injectors. So I'm not surprised if this is happening, just disappointed.
But is it a measure of the injectors working? Or the signal that goes TO the injectors? Is there another issue here, software or signal related I'm just not seeing?
Thoughts?

I was hitting AE at non desired times while it was anywhere between 20-70, at least I thought. I'll lower it, but surely the duty cycle pulse width jumping has got to be the true culprit here. Right?

In this last log you posted, AE hit four times on decel to 97% of your normal fueling value, for one cycle, event, whatever.
AE is not the problem.
TPS never above 10% in this log, though, so... TPSDOT also never went over 32%.
Are you even looking at this **** before you post it?
Megasquirt knows nothing about the injectors. It grounds out a 12V line for a specific time to open the injector, nothing more.

It's doing exactly what you ask it to do as far as I can tell. You give it gas, it revs to 1500, you give it more, it falls on it's face. You stay in it, and it oscillates or rings till you let off.
It's almost off your wideband it's so lean, so you should fix that. If you can't fix it in the VE table, then **** might be broke.

Should I have "incorporate AFR target" enabled on my general settings? I'm shooting in the dark here and grabbing for threads.

open the AE screen.
watch your TPSdot ticker as you idle; set the threshold above that with maybe 10 points above to rule out noise.
you want the threshold as low as possible without false triggering from noise.
I also like to blend in a little MAPdot for good measure. maybe 75% TPS to 25% MAP.

Roger, I'll see what happens with those settings. Seems promising.

Gotcha, I do however have the log that shows my range can go from xx%/s to 1216%/s, so at least I know how far on the %/s axis to make the graph, I just have to tune the added spray in ms until it stops leaning, but does not bog.
I appreciate all the help.
