Having issue deletin gECT torque Management during 1-2 shift

[Brad Kimbler]

Tuned 2003 GMC truck with a cammed 4.8. all was going well until we increased the 1-2 shift point then we noticed a big delay during the 1-2 shift, on the scanner it show TPS going from 99.6 down to about 30% then back up to 99.6. I also noticed that the commanded A/F goes to 14.68 ....even after the completed shift....I think disabled all the abuse tables and tq managment reduction tables but there has to be something i am missing. What also puzzles me is that there is no TPS dip on the 2-3 shift like there is on the 1-2....

What has to be done to get the pedal TPS to match the actual Throttle blade on drive by wire setups...

I started to modify B6612 but felt no difference setting the 5000+ rpm cells to 100%, Any ideas?

Here is the log showing the Throttle TPS falls to 30% during the 1-2 shift, no timing falls, just TPS

I think I just found it...When I increased the rpm shift point I didnt increase B5401(ECT rpm limit) This makes sense as the 1-2 is set to shift at 6100rpm and the 2-3 shift set to 5750 ..only happens on the 1-2 shift as B5401 is limiting rpm to 5900(right where ECT fallsin %) Now to test
