Pete,
What's interesting about the ZR calibration is that AE is based on MAP. There doesn't appear to be a table for Delta TPS%. There are some TPS% Constants in oorder for MAP AE to take place but nothing like the AE PW based on Delta TPS%. When I tuned my 84 using EBL, I relied more on TPS % change than I did on MAP % because it reacted faster and then I would decay out the AE. But that's on a wetflow TBI system. In talking to some other tuner friends it seems that GM may have used the VE tables to add AE. And the Decay for the AE PW in my calibration is immediate. Once the
AE PW is delivered, ITS OFF. Also, the AE PW is the same in the 92 AYWT bin regardless of Delta MAP. I'm sure part of the reason for this is the second injector. It makes up for lack of AE fairly quickly.
Is the stumble you have all experienced more likely at lower or higher rpms?
