When asking for technical help at the very least let us know the version of firmware you are running.Cliff's Calibration (Mapping) Guide is a MUST READ: http://www.vemssupport.com/forum/index.php/topic,97.0.html
Do you have the Eclipse triggering sorted?
That wheel will give you sufficient triggering to drive wasted spark and sequential injection.
