I hooked up the box and my timming is dropping like 20 degrees. from unhooking the crank trigger to the 7al to connecting to the retard box. I have zero in all 3 retards. I have the same box on my other car and I don't remember it changing at all. until you ground the wires for it to retard. I called msd and he told me to make sure the 3 wires for the retard are grounded. which I rechecked and they are. which shouldn't matter if I have zero in all 3 retard slots. anyone else have this box have to move the timming this much hooking up the box.I don't have the start retard hooked up either. thks Danny
