6R80 & Forced Induction Shifting Issues

[olaosunt]

60' and 1/8 mile et don't match the MPH.

I was cutting 2.3 60' and running a 7.4 at 100mph at north star with nearly a 3000' DA with my 62mm TT Car

DA was 2000'.

Do you have a manual or auto?

The auto shifts slowly as even I can do better than a 60-330 ft of 3.2 seconds(usually 2.8-3 when I was shifting they MT82 on my 12).

The 60-660 is also slow at 5.6 seconds(typically 5.4 seconds when I was shifting my 12)




Could that account for high 1/8 mile and 1/4 mile ET despite the mph?

Does not look to far off to me. My '13 with a Paxton picked up 30 mph out the back.

Ran car again last night.
Bad night overall.
My snakebite/TVS/12 snapped the 8 rib belt again first pass after auto swap.
I tested out the new ET R's on the 15. They did not hook at 20 psi or I may have overdone the burn out.
Spun on the line( and between shifts ?- did not feel it) and could only run 12.0.Trap is still consistently high 120's.
I am getting a little frustrated as only reason I got an auto was to shift faster than I can and run quicker than I would with a manual.:frusty:

After only one revision from BBR I decided their tuning sucked. Waiting days for a revision after logging passes at 135+ mph on the street was not how I wanted to get my car tuned.

Will TSS do remote tuning?

 

[Nomad]

I don't know if they'll remote tune it or not.

I can tell you that my shifts are night and day different compared to BBR's tune.

Will TSS do remote tuning?

Yes they will but you will need ID 1000 injectors.

Daniel said he's already encountered shifting issues and knows how to correct them.

Will TSS do remote tuning?

I talked to Daniel a few weeks back, and at that time he wasn't ready to take on remote tuning. I hope he will as I should be getting my car back with the Hellions late next week.

I spoke to him 2 hours ago and he seems to be ready and confident.

Nice, I'm just trying to find someone that can if I have problems when I get my car back.

There you go!

Nice to have a back up plan.

This is good news!

Ran my auto/hellion car.Gears are 3.55 and tires are balding NT05 R 29 inch tall so less gear than 3.55.
Running base setting boost levels(5-6 psi?) .Car gauge still only reads 1 psi but I confirmed it is definitely making boost.Lol
My 12 trapped the same when it ran 10.8 and made 620 ish.
Does not pull out of the hole hard although I am sure higher stall converter will help( not going to do it as I hated it when it was in my 12 although that has a TVS).
I now see what has been said about the slow shifts.
I would love to turn boost up before my dyno appointment this Friday but now kind of scared of the boost controller.

So I had the car on the dyno at Fat house this friday.

They are the guys doing the fabrication for the SBD TT car and I got to look at it while I was there.It looks very nice and it is almost done.
They were waiting to fit it with ball bearing turbos.
The turbos are low mounted but the filters are placed next to the turbos unlike the on3 design which places them behind the front bumper.
I was not allowed to take pictures although they took plenty pictures of the Hellion-Lol.

They made 2 pulls back to back both in 4 th gear.They logged boost@7 psi.
Numbers don't match the trap speed which has been consistent 127-129 mph for a full weight,automatic premium car.

I got a tune revision from BBR just as the car was on the dyno(did not see it till later) and it is night and day over previous version.
Also put back my suitcase as car was just too loud with the resonator delete and Kooks axle backs.
Sounds perfect IMO now although I may try welding some bullet mufflers unto the resonator delete.
I am going to run the car tomorrow again with the new tune and data log.

Im very close to you on my 6lb numbers. I did 533/520. I haven't had it out at the track yet but it feels real strong.

 

[Travis@boostworks]

Lots of folks haven't figured out how to properly tune the trans yet.. The strategy is completely different from the 11-14.
