Smarty 13-15 Dodge Ram Cummins 6.7L Diesel ComMod
The Smarty ComMod Communication Module unlocks the most advanced real-time tuning capabilities for 2013–2015 Dodge Ram 2500/3500 Cummins 6.7L trucks when paired with Smarty Touch tuners, providing dual CAN bus access to the ECM for on-the-fly power adjustments, VGT control, and sensor monitoring that outperforms basic flash devices or older tuners through seamless shift-on-the-fly functionality and ECM unlocking without security risks. Engineered as an under-hood expansion port, this module taps into the secondary service bus to bypass 2013+ ECM protections, enabling full CaTCHER tune integration with Smarty Touch for up to +170 HP gains while maintaining no-trace stock returns and diagnostics compatibility. With vibration-resistant wiring and plug-and-play connectors, it equips diesel enthusiasts and shops with a reliable add-on that enhances towing response, throttle mapping, and data logging better than standalone programmers, all while supporting UDC custom tuning for precise fuel, timing, and boost calibration across demanding loads or daily drives.
