Anyone else interested?

I don't have the connectors, so they will have to be spliced in.

I'm making a couple for others and will end up with a few extra to pawn off.

Should work well for the do it yourself dual CP3 Crowd.

My brother found the part #'s for the male connectors that plug into the regulators when we made the triple controller for my truck, i could see if he still has the part #'s if you're interested.

I'll have to run that diagram passed my mom. She used to build PCB's for a living. If she doesn't want to make it then put my name on the list for building one as well.

Triples are easy, but they might be a bit twitchy.

If you dont mind sharing more? What are the challenges associated with triple cp3s? With my new injectors I may need more fuel than what my twin lbz cp3s can supply. I like the idea of triple stock pumps opposed to dual modded pumps. seems like it would be cheaper and more reliable>

I think the reason Jon says that triples will be touchy, is because you are exaggerating every single little control 'movement/adjustment' that the ECM does. The ECM PID ('closed loop') control of the factory CP3 was never designed to work properly with more than 1 CP3. We can kinda get away with it with 2 CP3's, but In order to smoothly control three CP3's, I would think it would be more ideal to "buffer" and "smooth/dampen" the signal to the 2nd and 3rd CP3's. Use the stock CP3 for the quick response, and then smoothly/progressively ramp in the 2nd and 3rd CP3's as needed...a "smart" controller if you will.

If I were making a triple CP3 controller, I would probably use the analog method for the 1st and 2nd CP3's, and then add an "as-needed" demand-based smart control for the 3rd one (a controller that looks at throttle %, rpm, and actual rail pressure, and then brings in the 3rd CP3 as needed)

JMO. Jon, correct me if im wrong.
