My AFM is'nt too bad feeling, it's when I'm watching it go in and out of v4 mode is when I can notice it. I could NOT agree more on the 6 speeds in our Lambda's, the trans shifts suck to say the least.EKinMN wrote:I appreciate the posting of the parameters. It's interesting information.
Still, all I want is for this engine to only go into V4 mode while on the freeway. I agree with an earlier poster about not having it kick in until above about 45-50MPH. The engine lugging is just annoying. It's especially bad if you do not feather the throttle. if you jump on it a bit while going slowly in V4, you get whacked as it goes into V8, and then again when it downshifts. That's just really bad programming. GMC really has some opportunity here, because my 6 speed Acadia shifts in a dumb way as well--completely misses the power band in 3rd gear. Do the GM programmers drive these vehicles in the real world, or is this purely a mileage play?
Sorry for the attitude. I had a long stop and go commute this morning, and this was noticeable and annoying, so it's fresh in my mind.
