Last night I successfully reprogrammed an 07 E38/T42 combo, an 08 E38/T42 combo and an 08 E67 with my home brewed benchtop system using GM SPS. The 2010+ E38's would not work, SPS would recognize that the system was not in a vehicle and not let me proceed. Does anyone know a work around? maybe install a BCM? From another thread on here I guess E37's do not work either.
