SOTF Switch for EZ Lynk | 2011–2016 Chevy GMC Duramax 6.6L | Dyno Diesels

Dyno Diesels SOTF (Switch-On-The-Fly) Power Selector

2011–2016 Chevy / GMC Duramax 6.6L
EZ Lynk Platform Only

The Dyno Diesels SOTF Switch gives you real-time control over horsepower and torque levels—right from the driver’s seat. Designed exclusively for EZ Lynk–equipped Duramax trucks, this rotary switch allows you to change power levels on the fly without shutting the truck off or reflashing the ECM.

This is not a gimmick switch. It’s a control interface that works in conjunction with properly calibrated SOTF tuning files to let you adapt power output to driving conditions instantly.

How SOTF Works

Once your truck has been flashed with SOTF-enabled tuning, the switch communicates with the ECM by referencing an existing factory sensor input. Depending on vehicle configuration, the switch may utilize:

• Fuel Temperature Sensor

• Crankcase Pressure Sensor

• Intake Air Temperature (IAT) Sensor

Each click of the dial corresponds to a different calibrated power level—allowing you to step power up or down smoothly and predictably.
