2G Timing in a 1G ECU

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. So when increasing 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.

Details

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

RPM 1000 1500 2000 2500 3000 3500 4000 4500 5000 5500 6000 6500 7000 7500 8000
Adj +1 -9 -13 -9 -12 -11 -11 -9 -8 -9 -9 -4 -3 -3 -3

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.

RPM 1000 1500 2000 2500 3000 3500 4000 4500 5000 5500 6000 6500 7000 7500 8000
Adj 0 0 -3 -3 -4 -5 -11 -9 -8 -9 -9 -4 -3 -3 -3
