Bike: 2006 XB12X

Have gotten comfortable with ECMspy and Megalog and have been attempting to tune out some of the issues and get better fueling for my current setup.

I have attempted loading a standard XB12 race map and a couple of tune maps from megalog. No matter what I load or what I change the bike will not sustain idle with anything but the stock fuel map when hot. TPS looks like it is functioning correctly but when returning to idle revs will drop as low as 500 then it will quit. She will refire and sometimes idle, and sometimes not.

Anybody else have an issue like this. I have read the tuning guide several times and am stumped on this issue. I have even done a map with NO changes to the idle cells but if the map is modified at all this symptom persists.

Cheers Ken
