Another Diabo question.
I have the i3, 8245. 2006 completely stock LS2 with 82,000 miles. Very happy with the ecm tuner. On the tcm, I have a question. It shifts fine with the stock tune. It shifts exactly the same with the firm and hard tunes. Like the pressure is not increased. It will change shift points but I expected more from the hard shift + 20% tune. Is it a tuner problem or do I have a trans problem? For the record, it ran 12.80s Saturday in 90° weather and I think that is pretty good for a stock LS2 with 2.56 gears.

Is there a setting for torque management? In Hp tuner I reduced that, also there is a pressure setting and force control. Changing it to downshift sooner at part throttle is also a very nice mod.
Nice drag time! The one run I made I got 13.2 with traction control on /face palm /face palm /face palm

Diablo does not have the option to change TM.. I can get that done with a custom tune by Lew, I think. I did max out the shift pressure. I went to the track a few weeks ago and i was brain dead that day. Left TC on every pass and ets were all over the place. I can live with the car as is but would like to tighten up the shifts a bit. I really need to run 13.0000 three times in a row at LS Fest.

I do have the option to turn off TM with the i3 8245 on my '12 with just the basic settings. I wonder if not available for yours because its a few years older and only available with a custom tune. I guess you could go back to the stock settings and see if you feel any difference there. BTW, I went to LSFest in Las Vegas. It was an absolute blast!
I will look again for the TM option but I dont think it is there. Ive been to LS fest in Bowling Green, the last 3 years but this will be the first year with a LS powered car.

Either way, load the hard shift tune then email me the last tune written from the i3 for the tcm and I'll take a look. sometimes the limits need to be raised a little more

Much of the TM is reduced or disabled in the provided tunes, but there should be a switch for the upshift abuse mode to be disabled I would expect.
