It would probably be a good idea if you posted your msq. Also look at the examples at
http://www.megamanual.com/seq/multichannel.htm which also explains the terminology and gives some procedures.

A two cylinder engine with a 36 tooth crank wheel would use 36 skip teeth - setting it to six teeth makes it fire the engine six times per crank revolution.
