Description

Take full control of your Cummins dual CP3's using your just your ECM. The CP3X2 harness allows you to control your Cummins dual pumps without an expensive dual pump controller. 

We recommend multiplying the stock FCA current table (D0787) on the Cummins ECM's by 1.6-1.7 as a place to start. The FCA current varies from truck to truck based on the solenoid characteristics, age, and idle lift pump pressure.

Higher lift pump pressures at idle will require more amperage at the top of the table (low desired fuel flow) to keep the rail at it's target pressure. If the truck will not start after multiplying the table by 1.7, revert back to the original tune and multiply by a smaller number until the truck starts easily, yet maintains the target rail pressure at idle.

This is one of the more time consuming calibration procedures on heavily modified trucks, so make calculated changes, so that you can dial it in as quickly as possible. Once you have the truck idling at the correct target pressure you may need to modify the middle and lower portions of the table to prevent rail pressure overshoot or undershoot.

Again, methodical changes in the FCA table will yield the best results. Use the EFILive Scan Tool to log your changes and adjust in the Tuning Tool as necessary. Keep in mind, more current is less flow, and less current is more, zero current being full flow from all pumps.

Theoretically you should be able to control 3 pumps with the 5000mA of current that the FCA driver is capable of. This may shorten the life of the driver in the ECM so it's best reserved for competition use.

    The FLEECE FPE-CP3X2 is an essential upgrade for those looking to maximize the potential of their 2003-2016 Cummins engine equipped with dual CP3 pumps. This harness seamlessly integrates with your existing Engine Control Module (ECM), allowing for efficient and direct control of the dual pumps without the added expense of a dual pump controller. Designed for performance enthusiasts, this unit simplifies the calibration process while enabling fine-tuned adjustments to meet your unique tuning needs.

    Installation of the CP3X2 harness streamlines the setup process for dual fuel pump applications. It is recommended to start with multiplying the stock Fuel Control Actuator (FCA) current table (D0787) by a factor of 1.6 to 1.7. This provides a solid foundation for your tuning, taking into account the variations that might arise from differing truck conditions such as solenoid characteristics and idle lift pump pressure.

    For those with lifted pump pressures at idle, higher amperage may be needed to maintain optimal rail pressure, particularly during low desired fuel flow situations. The unit facilitates methodical calibration adjustments, ensuring a balance between idle reliability and performance optimization. Leveraging the EFILive Scan Tool, users can log modifications and fine-tune their settings effectively.

    Compatible with an extensive array of Dodge Ram models, including SLT, Laramie, ST, and more, the FLEECE FPE-CP3X2 harness is built to cater to the specific needs of your truck. Enhance your dual pump setup and achieve superior fuel management with this robust and versatile harness, designed for both casual drivers and competitive racers alike. Elevate your Cummins’s performance with precise control and adaptability, setting yourself up for success on and off the road.
