JMatt get's the go ahead from Sharadon Performance

Hmmmm - I'd give you 25HP over me, unless your car was lightened a bunch. That 129 MPH trap is huge!

I'd feel pretty safe at 650 at the crank. 700 at the crank may be the right number, but I think it starts to get marginal around there.

Only took us 3 years to get there. LOL

 

I am at full weight. At the track I tipped the scales at 4480lbs. The light launch I thought results in higher MPH.

I judged the HP numbers based on the fact that I never had an issue when the car was 550 RWHP, did my SCT tune and rolled off the rollers at 700RWHP then drove directly to the track and had the same shifting issue I heard in your 11.1 run video (slow 2-3 shift).

 

Chad, you had the same shifting issues?

 

Half a dozen guys have had this issue now. I expect 20 guys will see this issue by July 1.

 

I need some AFCO Racing rear coil overs for my truck. Hook me up......Please!

 

I can do that - but I need to see the truck first.

 

Matt, hope ya don't mind a different take on this. I'm with hemisfear about the TCM. Now I'm not saying these trannies aren't indestructable, but from my limited experiance with the Diablo TCM tuning, the SC and the Mopar and all the logging and playing around with the tranny over the last couple of years. Plus a couple converter swaps. And some very direct tuning with CMR aimed at torque management. I have a hunch a majority of your problems at this level are programming.

Have you completed any temp tests on your runs and or monitor'd line presure. You may find the results very interesting comparing the Diablo TCM tuning verses stock just on tranny temps alone. I will say that the Diablo TCM ran my tranny very hot. I gained 30-40 degrees across the board. And changing back to the Mopar and the SC dropped her right back in line with where I normally run.

Also, over the last couple years. There have been some fast runs. Granted no where near yours and Chads times. But also no hint of tranny issue. All the guys that have experimented with different TCM's will tell you (at least everyone I know) that the Diablo TCM is crap. Tons of slip, heat gain and other minor complaints. But on the flip side, we have no other way of attaining raised shift points either that work so well.

Anyhow good luck guys, sounds like a fun experiment.

 

follow my next new thread you guys will like this

 

Then post it already you tease!!!!

 

That would be correct. Add me to that list. lol

 

Yes I did.

If I didn't lift at shift time the RPMs hung at 6K for most of the track. It sounded like a CVT trans (constant rpm, changing vehicle speed).

I would definitely be in for quick hard hitting shifts. I think there is time lost here.

 

Good luck I think you are in great hands

 

Exactly the same symptoms. Starts the 2-3 shift, hangs at 6,000 rpm, won't complete the shift unless you lift.
