Ya the instructions suck at best. I have it set to curve K at the second, 5, 1 on the switches. Timing is all fubar right now after I drove it. Kicking back through the manifold like crazy. Got the E-Curve to work though, had to do it in a round about way though.
I'm going to call MSD on Monday about that compatibility issue, it's been on my mind lately but no issues that I can see though, I am running a 6A box with it though.
Yes it is VERY tight with the wiper motor, not sure how to solve this other than removing the wiper motor
