More AE definition witth RPM multiplier/EBL

When I change by AE PW it does so in multiples of 61 usec

As it stands today I am seeing too much AE in my WB logs (9.9/1) even though I keep pulling fuel.

AE TPS: I have 122 usec from 50% to 19% and 61 from 16%-0%
AE MAP: 122 @ 80 MAP to 70 MAP and 61 @ 50-0 MAP.

I already pulled RPM down to 1.5% at 2400 and 4.7% at 1400.

If I pull more AE from TPS/MAP will adding some in the RPM table allow me to split the diff in the 61 usec multiples. Is AE-RPM a REAL % ???

Issue is approx 16 lbs FP at 60 MAP and 20 lbs at 100 MAP with 80 lbs injectors.

The 61 usec steps in the AE PW is really from the CTS compensation table. This happens when both the PW tables and the CTS compensation are taken into account. It is so that enough AE can be generated with a cold engine.

The RPM compensation table is truly a percentage. And can both add or subtract from the AE PW. This is done after the CTS compensation takes place.

Re: More AE definition witth RPM multiplier/EBL

Thanks. Good news. Seems as though I need more AE at lower RPMs just for daily driving. Once the RPMs rise >2400 it appears the velocity in intake tract carries the engine/vehicle nicely and little AE is necessary. Cetrtainly PE is there one the TPS value is hit. I posted once B4 the the throttle follower fueling I added is huge. I kept feeding it fuel and now the easy acceleration from a stop is so much improved(manual). I am watching the integrator and I dont see it reacting(rich) so that is a good thing. I believe my TF value is 1000 usec!

Re: More AE definition witth RPM multiplier/EBL

Very old thread, but I thought it was informative as to how the CTS multiplier and the PWs for TPS and AE fit into things.

I have an automatic transmission. When I am just over the speed and rpm where I would get down to a 1st gear WOT downshift it will drop to second (again, too high for first) get some AE, and then go into go into PE. I'm at about 2k rpm or so when this happens. My AFR will drop to about 13.6 or so and then as PE takes over it will go to the 12s.

Does the RPM multiplier table come into play at the point AE is called on (snapshot look up at an RPM) or is it used continuously throughout once in AE conditions are met- in effect as you travel across the rpm at each row it is adding/ subtracting?

Hope that made sense...

Each loop through the AE routine uses the current RPM value. So as the RPM changes so does the AE compensation via RPM.
