I'll say it again It's a great product! It also has 7 preprogrammed timing curves built in. mercury 425hp up to 800sc, general timing curve for n/a engines, and a curve for high performance engines with the anti-stall feature activated. The instruction manual shows the actual timing curve your selecting. Just set the dial to what you need.

Mild, are you running HI-6M's, or other Crane boxes?
