Yamonda Posted August 6, 2020 Share Posted August 6, 2020 (edited) HI, I was just thinking about using the PWM output for the waste gate to control a SSR to run the fuel pumps. This is just a brainstorming thing for me. I have 2 walbro 460's and they draw heaps of power and flow to much for my fuel pressure reg. They also melt the wiring and connectors that KPM supply with the intank surge tank. I'd prefer not to have to cut up and make a new connector for the module but i probably will have to. It'd be nice to run them at low power when off boost. Anyone know the frequency output of the signal? I know it's probably more pain than what it's worth or i could run a standalone controller with a pressure switch. And yes i know i should upgrade my pressure reg and get rid of the crappy KPM module but i'm over spending money on it for a bit and thought i may be able to do something different Thanks P.S i use a standalone boost controller Edited August 6, 2020 by Yamonda extra info Quote Link to comment Share on other sites More sharing options...
Roland@pcmtec Posted August 6, 2020 Share Posted August 6, 2020 It is 32hz but it will cut out at idle etc so it would not be appropriate. Best option is to stage two pumps from the imrc output. We have set it up with an rpm and map pressure set point. Quote Link to comment Share on other sites More sharing options...
Yamonda Posted August 7, 2020 Author Share Posted August 7, 2020 Thanks Roland, That's about what i expected, 32HZ is way to low for pwm control anyway. And i was kinda expecting issues the the output been inconsistent. Unfortunately the pumps are paralleled in the module so can't stage them easily. I'll have to come up with a different way. Thanks for your input -Kyle Quote Link to comment Share on other sites More sharing options...

Just on this, this would be possible in the ba-bf easily to access but whereabouts would you be able to hook in to this for fg onwards, being log manifold? Does the wiring exist? might be a silly question Quote Link to comment Share on other sites More sharing options...
