Need a Holley Pro-jection unit

I have been running the Holley Pro-Jection system and after much heart ache got it working great. I now have a bunch of extra parts or am in it pretty deep and the brain or control box has died. Holley never supported their product worth a darn but now do not sell any parts as they have discontinued it. I am looking for a known GOOD ECU or control box and would rather buy from fellow CC'r than some Ebay stranger. Anybody have a box or unit that they could never get working right so they want to get out of their shop? reply here at CC or to jeffc@cobrasnvettes.com
THANKS All

Holley sent me a software update for my ProJection 4Di unit ... but it's a bad thing to hear that they are no longer supporting the ProJection units! (Keeping my fingers crossed that mine doesn't die.)

What happened to your control box? How did it die?

Petek,

My 4Di stoped sendind consisant and proper lenth injector pulses. It quite sending the signal to fire the injectors and is not consistant.

I MAY have one of those units in a box in my garage; my unit shorted out the injector wires, but the box should be in good shape. I will have to let you know Monday........

Which unit do you have? I have one of the early units with the trim pots on the box. I bought slightly used from someone I know for my 460 and have decided to go with a carb. instead.

The 4Di is the one without trim pots or is the laptop adjusted unit. Because of other options I can not use the old style. Thanks for replies and looking for me. Jeff C
