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.:D

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.

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.

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 ;)

Mike, thanks for the reply. I will get out to the car and pull the tune from it today.

PM sent.

This will be my first year. I went to nmra last year

You will not be disappointed . Something for every car guy. Show cars, drifting, drags, autocross and more. I cant wait.:cheers:

need to set something up so all these people on the forum can meet up and have a beer

We cant be the only forum guys going. Maybe in September, post threads in C5 and C6 general. C7 general too. They let LTs in also.

What is this "beer" you speak of...
