SCT turbo brake

[2006PSDSD]

Has anybody used this? Can anyone tell me how it works? I haven't got an idea how you can control the turbo electronically?

The turbo is already controlled electronically. My guess is they just control it with their tune to cause backpressure. I would like to know exactly how it works and how effective it is. I would think that the downside would be that it is always on.

This would be like having a jake brake turned on all the time with no switch to turn it off. Everytime you let completely off the pedal, the exhaust brake is on. Pretty annoying for the average driver.

Hopefully they have found a way around this, but this is my understanding of how it works.

Innovative diesel told me that you can feel it a little in the aggressive tow tune all the time, but it doesn't really work unless you have the tow/haul mode activated on the shifter handle. I was talking to my brother and we're thinking that all they do is control the turbo vanes, and like you said increase backpressure. I wonder if that will effect the EGT's at all?

[720Deere]

No fuel input during deceleration equals no increase in EGT. Unburnt fuel burning off during it's exit through the exhaust manifolds is the culprit of high egt. I assume that this tune is opening the vanes and basically causing full boost with no fuel. This creates a full combustion chamber that has to be compressed before exit with no fuel to combust and "push" the pistons back down. It essentially takes care of the inherent diesel design problem of no butterfly in the intake to restrict airflow and help hold back on the hills.

SCT turbo brake is very nice for towing, especially when you couple it with the tow/haul mode of the tranny.

Ok, now you have given me yet the final reason to get me an SCTs. I must have one of these toys now and if it will increase breaking while towing, i can justify it!
So the turbo brake is a seperate tune or is it programed into another tune like the tow tune??

Yes CHenry, it is programmed into my aggressive tow tune. I got mine from Eric at Innovative Diesel, they are the ones that created the turbo brake. Your going to love it, especially if you want new tires and the wife says no

guys, i ran across this will searching for 'tunes' for my 'wants' list - which includes an sct.
check out this site: Elite Diesel.* Welcome to the Elite
full of info. pull up vehicle specific info. & tunes. it describes the tunes available and how each works.... happy searching

How much are you guys towing with a SCT? I was told not to haul anything more than 8500#s. That is the main reason I have not gotten one.

I have had the understnading that the limit applies to their power tunes, i.e. the extreme power tunes.

Anyone that has info different, feel free to chime in...Logan? I think this is something we dicussed?
