I didnt do anything at all. Well come to think of it I loaded my map into it so i could start my car. Which setting is different? I didnt do a thorough walkdown of all your settings, figured tach spikes would either be the board or the car.

As far as the spark....refresh my memory. Did that MS have the internal ignitors? If you dont know, look at the db37 where the harness plugs into it. look right below it, if there are little screws there, then it has the internal ignitors. If not then your setup for an external ignitor.

How are you wired right now under the hood as far as the coil?
