DFI GEN 7, Code 72
I broke down today. While cruising, it started sputtering, backfiring and eventually cut off. It will start horribly and run rough while MSD fed tach and Calmap display tach jump all over the place.
I went into diag view and watched the cam/crank signals and they are erratic. A code 72 popped up after few times trying to restart.
Since I am not at home I do not have any literature on hand, I was wondering if someone could provide a little guidance.
INFO: Accel gen7 with accel dual sync, set up to run sequential. It has performed well for last 6 months. Initial installation was smooth and timing was verified then. I can't check it at the moment, so I don't know if maybe the distributor moved or even if that would cause this.

I just got off the phone with Accel (more on that later) and based on my description of the problem they want me to send in the distributor.
I had a feeling, there really isn't much I can check or fix on this thing.
Anyway, they picked up on the second ring and were able help me out right then. This is better than just 8 months ago and much better than the reputation.

Because I like talking to myself I will finish this out...
I got the distributor back just 5 business days from when they got it. They replaced the board and a harness. The harness was apparently rubbing on something and it went through the insulation, this could very well have fried the board, I don't know, I didn't ask.
They probably could have made a case for charging me but didn't. Labor, materials and shipping covered w/out even providing proof of purchase date.
So, up and running again.
If you found this on search;
Go into Diagnostics, select ECM and Diagnostics and monitor the cam and crank signals in the Powertrain box. You should get a cam signal for a moment, then watch for 8 crank triggers. The number box should go through the firing order and then start over with a cam signal.
I was getting a cam signal every 2 or 3 crank signals so it wanted to start over at #1 again and again.

The right tools are a necessity:
Hammer, Sawzall, and Duct Tape - that should be all you need for the successful installation of the Accel Gen VII
(sorry Mark - I couldn't resist
