Proper Timing Advance
#11
The Megasquirt is one choice, yes.
I'd rather keep it all original as much as possible *grins* Just a'hankerin' to tune something, and dasn't dare do SWMBO's Cougar until I have a proven record (it's why teh truck will be self-painted first; if I do good, I get to do her car. If I screw up, someone else does her car. I'm not sure which one is the better choice .... *grins* )

I have no idea....that 3.88 was off an engineering drawing...I don't have a flywheel on my 90 The point was to show the math...if 11 inches it just means that the arc distance is even greater for one degree of change.

About the crank sen
I came up with a little less than 7.5 degrees for half an inch, using a quick calculation of the flywheel circumference and dividing that into 360. So either way a significant change is needed in the mounting position of the crank sensor to get a good start point on the "advance" side I'd say.
