Default TPSdot threshold for EAE and AE

It's been well covered that EAE is for light throttle manipulation, and AE is for quick stabs. I've got my EAE feeling good to what I consider light throttle manipulation. However, "feel" is very subjective. I want to start fine analyzing my data in MLV by plotting MAP vs RPM vs TPSdot in one graph. Narrowing the rpm window to 2800-3200 rpm Then in the second graph I will plot MAP vs RPM vs AFR using the same narrow window. This allows me to isolate a single TPSdot value at around 3000rpm and the corresponding AFR value at the same point.

1. As far as TPSdot values are concerned. What value do you consider the line between fast and slow throttle manipulation?

2. Is my above method flawed because I will see the instantaneous AFR and not the resulting dip or spike associated with the throttle movement?

Arre you on the newest frmware? Alpha 17? There's improved smoothing code to be able to sginificantly lower the threshold. Without it im stuck at at around 70 rate/sec which is too high but my tps is nosiey and triggers events iif the threshold is lowered.

I can get mine down to about 35 rate/s. (yes, alpha 17) Even though I can set my threshold this low...Is it a good idea? At what throttle speed does the EAE start to break down, or not be able to keep up with demand?

It may be that EAE works fine up to 70 rate/s.

I have good results with AE tpsdot in alpha 17 at about 35.

I dream of 36 r/sec.

My latest log shows that I could get away with less than 20 r/s. I left it at 25 r/s since this seems to be the rate I use to leave stop lights.
