Fleece FPE-CP3X2 CP3X2 harnesses – 2003-2018 Cummins 5.9/6.7L

Description

Take control of your Cummins dual CP3’s effortlessly with our CP3X2 harness and your ECM. By multiplying the stock FCA current table, you can fine-tune fuel flow without the need for an expensive dual pump controller. Start by multiplying the table by 1.6-1.7, adjusting as needed for idle lift pump pressure. Use the EFILive Scan Tool for logging and fine-tuning, ensuring optimal rail pressure at idle. Remember, more current means less flow, while less current means more. You can theoretically control up to 3 pumps, with the table allowing up to 5 amps of current.
