Engineered specifically for 2003 through 2018 Dodge Ram 2500 and 3500 trucks powered by 5.9L and 6.7L Cummins common-rail turbo diesel engines running dual high-pressure fuel setups, the Fleece Performance Dual Pump Controller (FPE-CDPC) provides an intelligent, plug-and-play electronic management solution. When mounting a secondary belt-driven CP3 pump alongside the factory gear-driven unit, both Fuel Control Actuators (FCAs / MPROPs) must receive synchronized pulse-width modulation (PWM) metering signals. Without proper electronic coordination, the two pumps fight each other, causing extreme rail pressure oscillation, surging idle, limp mode, or dangerous over-pressurization.

Unlike passive splitter harnesses that force the factory ECM internal driver to carry double the amperage load and require time-consuming custom table modifications, the FPE-CDPC is a dedicated standalone microprocessor module. It intercepts the factory ECM’s high-pressure fuel command and generates an isolated, synchronized drive signal to actuate the secondary CP3 pump in perfect harmony with the primary pump. Built with automotive-grade, weather-sealed wiring harnesses and OEM-style Bosch connectors, the FPE-CDPC ensures immediate rail pressure stability, predictable throttle response, and smooth idle manners for twin-pump setups powering 800 to 1,500+ rear-wheel horsepower.

Key Features & Benefits

• Dedicated Microprocessor Control: Reads the factory ECM metering command and independently drives the secondary CP3 pump without placing extra electrical load on the engine computer.
• Eliminates Custom ECM Table Retuning: Synchronizes dual-pump fuel delivery right out of the box, avoiding complex and finicky FCA current table recalibration.
• Rock-Solid Rail Pressure Stability: Eliminates common twin-pump drivability issues such as low-speed rail pressure spikes, hunting idle, and pressure drop-off at wide-open throttle (WOT).
• True Plug-and-Play Installation: Equipped with factory-style Bosch weather-pack connectors that snap directly into the factory and secondary CP3 metering actuators without cutting, splicing, or soldering.
• Rugged Sealed Enclosure: The solid-state controller module is fully potted and sealed to endure high under-hood heat cycles, heavy engine vibration, moisture, and road salt.
• Universal Dual CP3 Compatibility: Works seamlessly with Fleece Performance dual pump kits as well as aftermarket twin-pump brackets from PPE, H&S Motorsports, and custom fabrications.
• Zero Core Charge: Brand-new outright electronic component requiring no core deposit or core return.

• Platform Application Comparison:
  • Choose FPE-CDPC (This Controller): When you prefer a standalone module that handles secondary pump pulse width independently without recalibrating factory ECM FCA current tables in EFILive or HP Tuners.
  • Choose FPE-CP3X2 (Passive Harness): When you prefer running both pumps directly off the Cummins ECM driver and plan to manually tune the FCA current table (D0787).
• Installation Tip: Secure the module away from direct heat sources such as exhaust manifolds or turbo downpipes. Connect the main power lead directly to the positive battery terminal (using the supplied inline fuse) and ground securely to bare chassis metal or the negative battery terminal to eliminate ground loop voltage irregularities.
