PWM question

[crazcj]

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

[Spunkster]

It will only activate when the parameters are met.

[crazcj]

so 0% is normal?

[Spunkster]

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

[crazcj]

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

[Spunkster]

a map pressure with more vacuum than you are reading from the map sensor.

ok so i got it to work, but the duty cycle percentage is really high. for example 60% is 10 psi, and i cant hit 45-50 psi how do i alter that? riight now i have the variable frequency box unchecked.

[Spunkster]

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

[crazcj]

ok so what is the default frequancy?
would you recommend higher or lower?

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.
