To make a long story short the box is bad. If you need tech help from MSD ask for Joe. If he's busy hang t f up and call back later! Even with him ask a bunch of ??'s so you don't have to call back or chase a problem like I did.
Here is most of the story.
Talked to one of the MSD guys ( not Joe) and he assured me that they checked it and it is not the box and if I bought a box it would be a waste of money. Told me to send it to him and they would check it again. Nedless to say in the mean time I bought another one after my truck failed to run Wed. night. (it not working may have saved my life and or a friends. I backed out of the stagging light and told Mike the guy I was racingto go by himself. He crossed completly over my lane at the finish line and rolled his truck 4 times right down my lane. He was not hurt.)
Thursday, when I unpacked my new box I called MSD and got Joe. Ask him a few questions about the new box then mentioned to him my problems with the old one. He remembered me and asked if I had run a ground to my (new 16 volt) battery. I said yep and he quickly said well the processor is bad in that box! WTH! Why didn't he tell me that a month ago. I told him I was going to send it to them so they could fix it. He asked me to hold the old box and was it a lot heavier than the new box? It was, then he said don't waste your $. That box is not repairable!! Again WTF didn't they tell me all this before I 2nd day aired my box to them to Cal. from Ga. and returned to me 2nd day air) and cost me a bunch of other $ by not running worth a chitte since May!
Probably been to 5 or 6 races where I would try to make a pass and have to load up because it wouldn't run!
Hope this helps somebody figure out an ign box problem a lot quicker than I did.
