Smarty UDC Tuning incl MM3 Hardware - Cummins CME 6.7L (2018)

The Smarty UDC Tuning with MM3 Hardware by DuramaxTuner (DT1205040101002) provides advanced custom tuning for Cummins diesel engines. It connects directly to the engine's 3-pin J1939 connector for real-time tune switching. The device features a 4.3-inch touch display (480 x 272 pixels, 16.3 million colors) with a twin CPU for rapid display startup (4 seconds), fast PID refresh, and ECM download times (up to 3x faster than competitors). It includes a Micro SD card for updates and tune storage, and offers two configurable (high/low range) audio and visual alarms per PID for safe operation. An optional MM3 Exhaust Gas Temperature Probe is recommended for accurate EGT monitoring (up to 2200°F) directly from the exhaust manifold.
