been playing with it in mine. no extra tables are need to smooth it FWIW.

How ever, I lost communication in my log when at that time in the video, theres about a .7 second area that my throttle goes to zero, and drop in fuel and timing too.....I dont know if maybe the harsh jump caused my log to mes up or something was loose or what....

I just looked at a video I have on my phone from my dad pulling with his truck at the same pull as the video I posted earlier. I can't get it off the phone right now, but something weird happened with the TCM and it kept shifting up to 4th and back down to 3rd. There is no bad defuel and hop.

Do any guys have a log of this that they could post?
Im not saying i know anything about it just like to see what mm3 is doing and at what rpm

Mike did you allready figure it out? Was it a ECM or TCM table

seems it would be in the TCM since it only does it in 4-low
