THough I'm sure it's dumb question, so please flame me AFTER giving the answer...

Looking at the AE vs Delta TPS

Why is it that the larger deltas have lower AE values? Seems counter-intuitive. I would think that a larger delta would require a bigger "pump shot" so to speak.

 

Unless theres something unique about port fueling, the AE should increase as the delta TPS, or the rate that the throttle is opening, increases. Possible error in def file?

 

Here's the AUJP bin.

As Delta TPS increases, pump shot decreases... unless I'm reading it wrong...

 

Maybe that table has to do with the amount of AE when the throttle is already open?

For instance, if you go from closed throttle to 25%, then you look at the multiplier for 0% TPS (since it started there) and give 100% of the AE. But maybe if it opens from 25% to 50%, the ECM will do only a 1/4 of the AE it would have done otherwise.

If that's not it, I have no idea!

 

Logically, in my opinion, Kevm is correct. I added a similar feature to the efi system that I'm currently using/developing, and it works. Once the throttle is open somewhat, opening it further has less effect.
