KPM PWM Fuel Module Controller (Jeep Grand Cherokee)

Part No.:
Jeep Grand Cherokee (2012-2021): JDPWM1500

KPM PWM Fuel Module Controller

KPM Fuel Systems have designed a Pulse Width Modulated (PWM) Fuel Module Controller that can electronically run the two pumps housed in the KPM 1500 hp Module and also be further upgraded to run the three fuel pumps as housed in the KPM 2200 hp fuel system and four fuel pumps in the 2700 hp fuel system  .

We have called it the KPM PWM Fuel Module Controller

Its main purpose is to control the supply of fuel flow in accordance with the engine power and fuel demand.

It does this by electronically controlling the amount of current supplied to the fuel pumps.

The KPM PWM Fuel Module Controller has been designed to be a direct fit addition to all KPM 1500 hp, 2200 hp, and 2700 hp fuel systems.

Cooler Fuel

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 vaporising 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 in turn 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 in all conditions.

Cooler fuel means increased performance

Vehicle Model Fitment

Vehicles Factory Fuel System Control Module (FSCM)
Jeep Grand Cherokee (2012-2021)

The Jeep  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 1500 hp Fuel System runs two fuel pumps at approx. 16-18 amps each. This is a total of 36-38 amps. You can see that the factory FSCM cannot support the amperage of larger pumps.

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

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

Advantages and Features

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

  • Easy fitment with instructions provided
  • Pre-programmed settings to suit supported vehicle make and model
  • OE Programmable when used on vehicles with a Factory (FSCM) Fuel System Control Module
  • 2 driver outputs at 40 amps each
  • Ability to run 1,2, 3, or 4 x high volume pumps
  • 4 gauge outputs 0-5v able to monitor eg fuel pressure, temperature, pulse width , amperage
  • On-board temperature protection sensor
  • Everything provided for a hassle free fitment

Summary

The KPM PWM Fuel Module Controller is a vital addition to all high performance, high demand Jeep fuel systems that require multiple pumps and or fuel modules.

It will electronically control the fuel pumps to reliably supply correct amounts of cool dense fuel, only when and where required for engine demands.

It is fully modular when fitted to an existing KPM 1500 hp, KPM 2200 hp, or KPM 2700 hp Fuel Module System

The KPM PWM Fuel Module Controller increases your power and engine reliability.
