i'm having issues with PWM boost control and was wondering if the PWM value should be displaying anything in "senors" tab in s300. i have 0% at idle

It will only activate when the parameters are met.

If the parameters have not been met to turn it on, it will be 0

What could I set the parameter to @ idle to have it engage?

Try different frequencies, it should help you find a better resolution for the duty cycle.

31 hz is right around where the hondata mac solenoids function well at. Gm solenoids like the higher frequencies. If you have the hondata /mac solenoid, tyr 31hz and report back here.
