Less fuel pump current = less heat = cooler fuel = more power

Supplying fuel to support 1500 hp and beyond requires two or more high flow fuel pumps, housed in one or more in-tank fuel modules. The drawback to this scenario is that two or more fuel pumps can generate quite a lot of fuel pump current meaning increased heat. This transfer of heat needs to go somewhere and therefore, heats the fuel in the tank.
This is generally not a concern, however if the vehicle is idling or being driven for long periods with a low level of fuel in the tank, the fuel may start to reach a point of losing its full energy potential or start vaporizing in the pumps or fuel lines. This can cause long cranking times and hard re-starts. In the worst cases, the fuel pumps will start to cavitate, lose pressure and not supply fuel as intended.

The KPM PWM controller is pre-programmed to monitor your vehicle fuel pressure across all engine loads which allows the controller to calculate the required level of electrical current to your fuel pumps. This, in turn, delivers the correct amount of fuel to your engine as required across all conditions.

Cooler fuel means increased performance

The KPM PWM Fuel Module Controller is used as a stand-alone controller and by-passes the factory FSCM.

The KPM PWM Fuel Module Controller is supplied with a fuel pressure sensor kit and wiring that directly fits your vehicle’s fuel system. The fuel pressure is then used to calculate the correct current required to run the pumps accordingly.

The Jeep’s factory fuel systems run one small amperage fuel pump (approx. 8-12 amps); therefore, the OE FSCM Fuel Module Controller is designed to electronically control only one small amperage fuel pump and no more.

The KPM 2700 hp Fuel System runs four fuel pumps at approx. 16-18 amps each. This is a total of 64-72 amps. You can see that the factory FSCM cannot support the amperage of larger pumps.

The KPM PWM is wired into the factory harness with plug and play connectors to mimic the factory FSCM control signal and therefore requesting the KPM Fuel Systems pumps achieve fuel pressure that the PCM wants to see.

Control of fuel pump current will keep fuel cool and dense preventing vaporization, retaining maximum energy for optimum power.
