This is the GM E41-L5P version of the HP Tuners Diesel Switch, a six-position rotary switch that works with HP Tuners' Switch on the Fly (SOTF) operating system. With SOTF loaded, the switch selects between the stock calibration and five custom maps without stopping to reflash the ECM.
Key Features
- Six-position rotary switch: stock calibration plus five custom maps
- Knurled aluminum switch knob and position dial
- 5' OBDII pass-through cable
- Application specific to the GM E41-L5P calibration — not interchangeable with the Cummins versions
- SOTF also allows map selection through the factory cruise control buttons
Fitment
Chevrolet Silverado and GMC Sierra 2500/3500 6.6L Duramax trucks running an HP Tuners upgraded E41 ECM, which HP Tuners supports on 2017-2023 model years. An upgraded E41 ECM is required before SOTF and the Diesel Switch can be used.
