As stated I’m new and trying to figure things out as best I can, anyways I recently bought a 2008 Cummins with 90k on it. After much reading and lurking on this forum I have decided to do a full EGR and DPF delete. Haven’t done the deletes yet but have parts on the way. Also I purchased a used Smarty S67. Tuner is not VIN locked and doesn’t have US in the serial # so I believe it should be delete capable. The problem is when I hook the smarty to the truck and choose “update ECM” I get “Error unknown software”. What does this mean? And what can I do now? Any help/input is appreciated, I am finding some info but most of it is several years old and I don’t know what information is still current.. pls help!!
