PWM fuel pump control
« on: May 11, 2022, 11:00:10 pm »
Is there a chance to add some features to PWM fuel pump control?
It would be nice to have PWM max and min DC and frequency adjustment. Right now I have controller that needs 10-95% DC control range and 100Hz frequency. If it receives 100% DC signal it will limit fuel pump capacity to 45% so basically this PWM control that we have right now is unusable in my case.
I know that it would be best to use pwm alternate table for this, but it is already used for other function.

I'd suggest adding it to the firmware wishlist here: http://www.vems.hu/wiki/index.php?page=GenBoard%2FUnderDevelopment%2FFirmWare

Developers don't monitor the forums.

Did it more than 20 days ago and not a word from anybody. Seems like developers do not monitor wiki anymore. Is there any VEMS development still active?

Yes, for sure. But they aren't spending their time on here.
