Using the Ecumaster PMU to control boost solenoids.

Hi,

I have a Twin turbo Volvo Pro Mod with a PMU16. Our boost management system has crapped out and we need to get a temporary fix until we can replace the faulty unit.

We have a staged boost solution as a backup system with 5 pnumatic solenoids.

One solenoid for burnout boost pressure. One for Start Line boost and three solenoids that should be activated in sequence by time. Two solenoids should never be able to be active at the same time.

Each time the clutch switch is triggered the sequence should reset and activate from the beginning.

How would i go about accomplishing this?

I've tried using a falling edge pulse formula. But by doing that i can't get the clutch to reset the sequence.

Any help will be very appriciated.

Sincerely

Anton Sandström, TP Motorsport Sweden
