The 1G ECU timing tables provides for a LOT of ignition advance. Many people think it's too much even for a standard 1G engine. But when increase compression or stroke, you may find that it's *WAY* too much. A number of people running 8.5:1 pistons from a 2G in their 1G have asked for settings in DSMLink to basically convert their 1G timing map to a 2G.

The basic table to convert a 1G timing map into a 2G using DSMLink's Timing dialog is listed below.

Note that DSMLink timing adjustments are active all the time, not just at wide open throttle. So I probably would not run the timing values listed above below, say, 3500 RPM. I might actually use something more like this.
