It's no longer on my car as I rolled and totaled it back in January. However the system is up and running on my buddy's car, still being controlled by MS, still using the "fast" frequency setting to control the pump.

Sorry for reactivating this thread again :?

But, I have a MS3X and would like to controll the pump via the MS3.
From what I have found so var is that the snow pump is being controlled with PWM - freq being 47hz
I also need to use a solenoid valve as the pump and tank is in the boot, after comunication with snow they advised to just connect it with the pump on PWM.

The pump is rated to 11amp at 220psi, plus what the solenoid vale draws.

I do not want to mod the msx3 - so can someone suggest a circuit that I can use as an external driver for this setup.

Thanks
Mike

I use the main board injector driver to pwm the pump and nitrous 1 for the solenoid
