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!!

I *think* that means the truck has newer flash than the S67. If possible you want to update the Smarty to the latest flash. Best to email Smarty Power and verify the problem and resolution.

Word of warning, do NOT use increased timing on the tune when loaded and be careful with the added power or your head gasket will be history. If there are ANY questions about injector health replace them ASAP or same problem, HG done.
