Footbrake + Two Step I can get 2600rpm out of the CircleD 3C before it starts to creep forward.

Transbrake I get alot more boost and load that I thought. Sorry the video is short/crappy, but it was a spur of the moment thing, and I noticed load and boost go way up, so I had to let off quick and add some more fueling....

Very cool! Hopefully this is a game changer for the turbo guys. People have been getting good 60's footbraking but seems it takes lots of work. Hopefully this will enable people to get some good 60's but also do it consistently and actually get some good reactions too.

Blower people better watch out :rockon:

:D. Yay!!! I figured it just be a matter of time before it happened. Had a friend trying it on his own car with stock solenoids but had no access to change computer and always got CEL and "throttle disconnect". Again I say Yay!

Now the important ?, does the Transbrake change the converter you need/would want?

knew this had to be doable considering the trans is already solenoid operated... excellent work and put me on the pre-order list.

a conventional Tbrake involves installing a solenoid that physically moves the pistons in the valve body...on the 6r80 the solenoids are already there so it should just be a matter of triggering them to allow 1st and reverse simultaneously. How CPR is accomplishing this is the trick.

Bingo. I had a feeling it would be a matter of time as well.

Ok, if the solenoids are already there... so there is technically nothing to install ? so how the heck is he making it work? :lol:

I'd guess Magic, either software or hard wired(resistor/diode) type of magic that tells the car: "it's O.K. 1st and reverse at the same time is normal". :D

Tree'd :lol:
