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.

Ok I will email them now and see what kind of solution they have. Another question, I have the parts to go ahead and delete my EGR and EGR cooler but I do not have the stuff to delete my DPF yet. Would it be okay to delete the EGR and run the truck without the tuner for awhile until I get the smarty issue resolved and get the DPF parts? Or do I need to just wait? Second scenario, if I update the smarty can I the. Load the tube with the egr deleted and the DPF not deleted? Or will I have to have the DPF delete done before I can use the tune?

You can delete the EGR with or without software. You will get a CEL for that. Most people in the past just leave it there and unplug it.

However, you will need to delete the DPF and install the tuner at the same time. If you install the tune and leave the DPF, you will ruin it. If you delete the DPF and don't tune you will get into limp mode.

Once you've updated (or checked to see) the Smarty then you should be good to go.

I just impulsively bought a used Smarty Sr. S-67US and I am worried that it will not work in my 2010 dodge 6.7L Cummins. I have read a ton of these threads from this site and others. Any info would be greatly appreciated.
