I've got an old XCal #1 that I used to program the marauder with, only other mod's are a JLT intake. I've had a check engine light for the past couple of month's so I went to plug in my XCal2 that I use on my Lightning for a quick view of the codes and no power? For some reason the service port will not turn on the XCal2, it's like the service port is dead? Anybody seen that same issue? Thanks!
