Question, Whats common way to test operation of controller?Does actual rail pressure follow desired? If so, the controller is working (at least in my mind that's what it means).

If you unplug 2nd cp3 regulator, what should happen?If you unplug the second regulator it should open that regulator and cause the rail pressure to go wide open.

That's my answers.

Somewhat OT but, dual fuelers fairly easy to install with the motor in the truck?

 

[MMLMM]

pretty easy, way easier out of truck though.

Dang it, not what I wanted to hear. Hmmmmmm.

Best way to check your CP3 operation is log actual rail pressure vs desired. When my controller wasn't working I could only hold about 5800psi going down the track when the tune was asking for 25k.
