Re: Debugger board for P4 ECMs



thanks,
I have a junkyard '727 on the way (sometime this week). first thing I want
to do is verify that everything works correctly (on the bench).
I don't know if I would need a debugger board for that or not. (the less
reverse engineering the better for me). I am interested in some of the
onboard data streams but probably wouldn't go anywhere with it.
