Default Ez-tcu ,transmission control, 4l80e

The device is connected, everything works.
BUT
I do not understand how to properly adjust
I need a smooth shifting transmission.
Now gearbox works like this: if the throttle is more than 30% and more than 2500 rpm shift very firm.
like a kick in the *** every shift. My head does not stand up.
But if 20% throttle and 1500 rpm, she is like a little cat, gently and smoothly

Out of the box it calibrated this way for the safety of the transmission.


You need to calibrate it to the requirements of the V12.


see page 11 of this doc

Nothing helps me
Today connected manual mode. This is much better, but at full throttle shift still firm.
Of course stock computer works much better. But it can not be adjusted.
I already bought a low gear 2.97, full repair kit and additional transmission. This is a project for the winter

Does not work. Pushes all the time. No quiet ride. Once is not tried. It's like a triple or more sport mode on the stock TCU.
Two weeks drove and tried to set up.
Tech Support TCI plainly does not answer.

Today moved the stock computer. The man who programmed it, is a genius.
Gently and smoothly shifts gears, no jerks, no unnecessary gear changes.

the good part about money,is there is always more where that came from!

think about it ,we damn sure are not gonna take it with us.
i'll see if i can find the info on the 6by6 6speed GM auto, modded from a 4L80E.

GM does make a new 6 speed atuo but the electronics have not been hacked YET!
and it is refered to as a 6L90E, google wikipedia GM transmissions.
