EFI Live AutoCal V3 Duramax Tuner with Delete Tunes | 6.6L LB7, LLY, LBZ, LMM & LML (2001–2016)Accessories
SOTF Switch for GM Duramax (2001-2023)Shop EFI Live AutoCal V3 tuners, custom tune files, and SOTF switches for 2006–2021 Ram Cummins and 2001–2016 GM 6.6L Duramax diesel trucks. Buy a complete AutoCal V3 package with tunes pre-loaded, add tunes to an AutoCal you already own, or pick up a blank device, all backed by Tuner Depot's diesel specialists.
Our EFI Live AutoCal V3 Cummins tuner ships with custom tunes loaded for your truck's model year and ECM, covering 2006–2007 5.9L and 2007.5–2021 6.7L Ram Cummins. The AutoCal V3 flashes your ECM through the OBD-II port, stores multiple tune files, and doubles as a data logger and code reader, so you can monitor your truck long after the install.
The EFI Live AutoCal V3 Duramax tuner covers 2001–2016 Chevrolet Silverado and GMC Sierra 2500/3500 trucks with the 6.6L LB7, LLY, LBZ, LMM or LML. Tunes are built for your specific engine and transmission, and the handheld lets you switch between them without a laptop.
Already have an AutoCal? Skip the hardware and order tunes only:
Tune files are matched to your AutoCal's serial number and your truck's details, so have both ready when you order.
Need a device only? The EFI Live AutoCal V3 blank is a brand-new, unlicensed unit, a good fit for tuners and shops that write their own files, or for anyone replacing a lost or damaged AutoCal before loading tunes.
A shift-on-the-fly (SOTF) switch lets you change between up to five tune levels while driving, with no need to reflash. Choose the SOTF switch and cables for Ram/Nissan Cummins or the SOTF switch for GM Duramax, each with the harness matched to your truck.
Doing a full build on a 2013–2021 Ram? Our 6.7L Cummins kits pair EFI Live tuning with the matching hardware in one order, available for pickup models and Cab & Chassis models.
Emissions-related products and tunes are sold for off-road, competition and racing use only and are not legal for use on public roads. Check the laws in your area before purchasing.
