Clutch management with PWM?

Is it possible to set up a PWM circuit with an ON delay and variable frequency output to control clutch lock-up operation?
I want to set it up to operate when the launch control is released.
I posted in the development forum but haven't had any response.

Your talking about a PWMable valve that operates at 1000's of psi. Good luck finding that. It is much easier to put an orifice or bleed valve inline to slow the flow down.

I dont need "1000's". I have a 480# clutch spring. My slave cylinder diameter is 1.75'. That's about 200PSI. I think i can find something.

You could use a line lock solenoid, a solid state relay and an MS output to control it. Push clutch pedal in, push button to hold, meanwhile full throttle, release button and PWM release of clutch. WALA. How some bikes do it with a delay box.

i am thinking about using a 3 axis accelerometer and running it through a table to calibrate the response.
