As long as it`s initial setup is correct with the wiring and coil connetions it will run prefectly.

Am i understanding this correctly?
If its running, leave it along...

Yes, each DFU fire 2 cylinders at the same time, the one on the compression cycle count, the one on the exhaust cycle does nothing.

Now I remember that my buddy was still on the normal distributor (his pre MFI days) at the time.

In conversations with Richard (Clewett Engineering) and in the instructions sheets, wirring is the biggest problem, read it 10 times and still screw it up

I'm starting the electrical this week-end... Will see
