 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. 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.
