Slow the clutch down, keeping the rpm's up. So technically, it's another way to accomplish an adjustable pressure plate. Gives it the same function as a, per say, 8" converter?
Technically...no. An adjustable PP doesn't slip the clutch, per se. The pedal is all the way out. The CT controls the speed at which the pedal comes out.
That's two different things. But if guys for whatever reason want to run a diaphragm PP the CT is the on,y way I know of to control the application of the clutch.
Why the love for that PP I have no idea. Other than cost, there is no reason to run that PP. That and idiotic class rules.
