For 2015.5–2016 Duramax 6.6L LML trucks, the factory DPF and EGR systems can contribute to exhaust restriction, soot buildup, and regeneration-related maintenance issues.

Standard vs. SOTF: Choosing the Right EFI Live AutoCal V3 Tuner

The standard version is designed for customers who prefer a conventional tuning setup without an SOTF switch. The SOTF (Switch on the Fly) version supports switching between compatible preloaded tune levels using the appropriate switch, where supported by the tune files and vehicle configuration. This provides added flexibility when different operating conditions call for different tuning levels.

Key Features of V3

• Custom Tuning Support: The EFI Live AutoCal V3 provides a platform for loading compatible custom calibration files tailored to the vehicle and its intended application.
• Vehicle Calibration Support: Depending on the supported vehicle, ECM/TCM configuration, and supplied tune files, the AutoCal V3 can be used to load compatible calibrations. Hardware changes may require corresponding calibration updates.
• Advanced User Interface: The AutoCal V3 features a color screen and updated interface for easier navigation and access to supported functions.
• Custom Tune Storage: Store compatible tune files on the device for use with supported vehicle configurations. Switching between tunes depends on the supplied files and selected setup.
• Portable Design: A compact handheld device that can be conveniently carried and connected to compatible vehicles for supported tuning operations.
• Configuration Matters: The available tuning functions depend on the vehicle, ECM/TCM, tuner configuration, and custom files provided. Please confirm your exact application before ordering.

2015 or 2015.5? 

2015 is a split year. The 2011-2015 downpipe is secured to the turbo-direct pipe using a V-band style clamp. The 2015.5-2016 uses a 3 bolt flange style connection. Be sure to visually verify the clamp style your truck is equipped with.

This ensures a perfect fit for all LML Duramax exhaust setups from late 2015.5 to 2016 models, whether you plan to run a 5" LML exhaust or maintain a more factory-style configuration.
