Engineered for serious diesel enthusiasts, this advanced tuner is ideal for Duramax and Dodge Ram diesel engines, offering unparalleled control over your vehicle's performance. Standard vs. SOFT: Choosing the Right EFILive AutoCal V3 Tuner The standard version offers fixed tuning, requiring manual updates for any changes, making it suitable for users who need a single performance setting. In contrast, the SOFT (Shift on the Fly) version allows real-time switching between multiple tuning modes while driving, providing flexibility for those who need to adjust performance quickly under varying conditions, such as towing or off-roading. For 2016-2021 Dodge Ram diesel trucks, a sotf switch is necessary to change tunes. Key Features Precision Tuning: Customize your engine’s performance with precision. The EFI Live AutoCal V3 allows you to fine-tune parameters to maximize horsepower, torque, and fuel efficiency, giving you the ultimate driving experience. DPF Delete Capability: Designed for off-road and competition use, this tuner enables the removal of the Diesel Particulate Filter (DPF), enhancing exhaust flow and delivering improved throttle response and power. Advanced User Interface: The AutoCal V3 comes with a larger, more responsive screen and an upgraded interface, making it easier than ever to navigate and adjust your settings. Custom Tune Support: Store and switch between multiple custom tuning maps tailored to your specific driving needs—whether it’s for daily driving, towing, or high-performance use. Portable Design: Compact and easy to carry, the AutoCal V3 allows for on-the-go tuning. With the ability to store multiple tunes, you can effortlessly switch configurations to match any driving condition. Important Notice This product is intended for off-road and race applications only.
