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
Without a lot of documentation on your setup, datalogs and config files you won't get much help.The injector FETs don't go without a reason. The grounding is probably messed up somewhere.
Ok I think I found the problem that the flyback operation input is nt enable. The port is closed on the settings. I am going to try it tonight.
