Josh Burt Posted December 1, 2011 Report Share Posted December 1, 2011 I just installed an Aeromotive 340lph pump in my vehicle. It is overpowering my fpr so I'm looking into picking up a pwm fuel pump controller. I see the Link software supports the WRX controller which has 3 speeds which should work out real nice for me. I am just worried about the controller being able to handle the increased amperage of this pump. Any thoughts? Thanks  Quote Link to comment Share on other sites More sharing options...
Stevieturbo Posted December 3, 2011 Report Share Posted December 3, 2011 Good question. But I think the OEM controller is just a basic hi/lo ? There are plenty of PWM controllers out there that could be used to control a pump. But most seem to be resistance based for their output. Dont know of any that allow a full PWM output from a PWM input....which would be perfect. Might just be easier to fit an aftermarket FPR ?

Josh Burt Posted December 7, 2011 Author Report Share Posted December 7, 2011 Just finished fitting the WRX one, so far so good. It seems the WRX community runs high flow pumps off of their factory controller without issue so I'll give it a try. Â Also this unit is a 3 speed controller.
