More AE definition witth RPM multiplier/EBL - Third Generation F-Body Message Boards

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.

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!
