How Much Amperage Can a WRX Fuel Pump Controller Handle?

Posted by Josh Burt at December 02. 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

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 ?

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.

 

Also this unit is a 3 speed controller.

Plug-In

Free yourself from the constraints of the factory ECU. Link's G4 Plug-Ins fit discretely inside the original enclosure. Installation is a breeze, no alteration of the factory wiring loom required. An XS connector provides additional inputs and outputs such as oil pressure inputs or anti-lag / logging switches (the number available depends on the application).
