Smarty UDC (User Defined Catcher) Dongle (smtUDC)

The Smarty UDC is the ultimate in custom tuning software for Common Rail Cummins that the "Average Joe" can actually do. We're not saying it's something that you want ANYBODY to program your truck with, but the majority of shade-tree mechanics will have no issue tweaking programs with the User Defined CaTCHER.

The highest goal at Smarty for the UDC was simplicity. Any professional tuner will tell you that the most time-consuming part of custom tuning is working out the right "base tune." There are hundreds of parameters that need to come together for a smooth, powerful, and trouble-free base tune. With the UDC as the base software, the highest CaTCHER in the Smarty is used and the customer then needs to fine-tune only the most performance-relevant parameters.
