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.

Great Start
Format: Hardcover
My 9 year old doesn’t like reading. When it’s time for him to read to us, this is his go to book. Chapter books are a bit intimidating for him. He is eager to read about Max and is wanting to ready without us asking. We are looking forward to book 2.

Not so great unless you are willing to accept a certain amount on faith.
Format: Paperback
Similar criticism to my review of the Black Holes book: "Starts off ok, but quickly loses you. I have an extensive science education and quickly got lost. This topic cannot be easily explained in a brief book - the author is forced to jump over certain building blocks, and that just leaves the reader confused. I think this book series is good, but maybe not for abstract science topics."

A fun read. Learned a lot.

I never expected to be able to understand Relativity or the more ethereal concepts of time. But Jenann brought them to my level. The language gets a bit flowery at times but I think that reflects that these ideas have a poetry of their own. RL
