so was there a final answer to this???
1. the advance is off at idle and turns on at 1050 rpm and then turns off at 4700 rpm (or whatever setting you have in datalogit)
2. the advance is off all the way up to 4700 rpm and then on from 4700 all the way up
to me option 2 makes more sense...but yeah whats the go?
SK have you tried any further experiments with changing this value from 4700???
