The ECM is corrupted somehow (as the DTC would indicate). Was it the 'E-ROD' ECM to begin with or the GMPP one? One is for pre 2009 ECM's the other is for the later 2009+ ECM's.
Someone got creative at GMPP with the E-ROD, there is a message in the flash that says "HOT RODDING A REVOLUTION IN LS3.E-ROD"
