My version of Tuner Studio doesn't show an NGC trigger. It does however show Neon 420A which is SOMETIMES used by MS2. In MS III you want to use the following trigger settings:

The correct wheel setting is 36-2+2 for all pre 2009 Hemis, I believe that 2010 and later had a different crank toner ring.
