From what I read it sounds like the orange ECU's made from about 2004 maybe and up are the ones giving trouble ? Thats because I bought two orange box's in 1996 and both are still going strong right now. One is still on my 63 and has helped it run 10.70's with no ign problem at all. I do plan to upgrade to MSD one day when I can afford it a little easier. But it just seems all the newer ones bought in the last 8 to 10 years are the ones that seem to give everyone trouble. Ron
