Set the base timing to the factory 10° BTDC. That's what your EEC believes it to be, and makes changes based upon that.

agree with above 10 degrees base timing, and since u have the msd timing retard 1.5 degrees should be a good number per lb of boost for your overall timing, assuming your running 8lbs.
