Okay, this is not about how to add an option like every other post. I know it has the ability connect up to a cummins 6.7 ecm and then do an injector kill test. I can only get it to connect to the my2013 ecm. I have the obdlink mx+ connector but the system only lets me connect to the lesser ecm setting where i have fewer diagnostics. Any suggestions on how to connect?
