I'm upgrading from a 7747 to a 6395. Because I use DIS instead of HEI, I had to program in Offset. The following Items had to be changed:
1) Initial timing (60*)
2) Maximum Spark Allowed (75*)
3) Maximum Retard allowed (-75*)

I was going to get ahead and started looking over tunerpro, the OD.XDF only has Initial timing.

What do I do about Max/Min spark allowed? and how?

thanks in Advance

Ted
