ya it got closed down again.. or at least put on hold, i left. High winds and rain
I got 3 passes in. First two were in 4x4 and it was still acting up at WOT and shifting in 4x4. It's frustrating, im pissed that I didn't get a full run in. I smoked two vehicles to the 60' and then looked like a jackass.
I am working with a guy online to sort out what's up. I am not even sure it's all tranny tune issues now. Somehow I will figure it out. Got a couple ideas and am going to go do some more data logging tonight to see if I can narrow it down.

that works all fine and dandy on the 4spd trans. the 6spd is a whole new animal.
if your engine tune is not dead on, your trans tune will be off. why? simple really. the trans is weighed heavily on torque/load calculations. then throwing a 3k stall into the mix doesnt help, but in the end, its that difficult.

runs amazing from a roll and most the times from a dig on the streets but something about launching in 4x4 and throwing everything she has at it... it gives me a big middle finger

Are you running a 1 bar MAF tune?
I know on my friends 6 speed G8 the tranny tune is opposite of my 4 speed tune. With the 6 speed to command a shift you set the rpm lower than where you actual want it to shift and set the mph to shift at the exact rpm shift point you want. Which is based on tire height and gear ratio. Also the more power you make the lower the rpm must be set at.
On 4 speeds you set your exact rpm and have the mph set a few mph lower than what is achieved at your rpm set point.

edit.
yea 1 bar MAF
Might have to steal Rogers Gtech thing to get a rough idea what it does in the 1/4 once I get things figured out

there are a few things in there i would change on the motor side.
there maybe a hard limit on the scanner side of it for commanded torque, but thats pure calculation.
as i have said before, if anything is off, it will directly effect the trans.
there is nothing on the torque management side to hold it back. the only thing on the trans side is the TCC limit in the last tab.
it uses the mph trigger as a first "ok" to get to the second "ok" which is rpm.
if you command 25 mph, it won't shift at 25mph. it will use the rpm at 5800 as the trigger. then comes into play is the trans torque load, air flow, commanded torque, blah blah blah blah. get the engine tune dead on, and the trans will be easy after that
