EFI Live AutoCal V3 DEF Delete Tuner | Ram Cummins 6.7L | 2013-2018

2013-2018 6.7 Cummins DEF delete tuner

The EFI Live tuner for 6.7 Cummins 2013, 2014, 2015, 2016, 2017, 2018 uses the AutoCal V3 handheld programmer to transfer custom engine calibrations to compatible Ram trucks. Designed for 6.7L Cummins diesel engines, it supports Ram 2500 and 3500 pickups along with supported 3500, 4500, and 5500 Cab & Chassis applications.

Unlike programmers containing generic preloaded tunes, the AutoCal V3 uses vehicle-specific files prepared for the appropriate ECM and engine configuration. For legally permitted off-road applications, compatible tuning can accommodate DPF, DEF/SCR, and EGR system modifications, with performance and power levels determined by the vehicle's selected calibration.

Why Choose

• Custom ECM calibrations: Files are configured for the supported model year, transmission, and engine modifications instead of relying on generic programming.
• Selectable power settings: Compatible Pickup calibrations support five SOTF levels for different performance requirements.
• Handheld programming: The AutoCal V3 transfers calibrations and provides diagnostic functionality without requiring a permanent in-cab display.
• Vehicle monitoring: Supports reading diagnostic information and recording engine data for troubleshooting.
• Flexible tuning options: Compatible files and additional VIN licenses allow supported configurations to be managed through the EFI Live platform.

Vehicle Compatibility

The DEF delete tuner for RAM 6.7 Cummins requires matching vehicle identification, transmission, body style, and ECM information. Pickup and Cab & Chassis vehicles may require different calibration packages.

Components

• EFI Live AutoCal V3 Programmer - Handheld electronic programming tool used to transfer compatible calibrations between the computer and the vehicle ECM.
• Custom ECM Tune File - Vehicle-specific calibration prepared for the selected truck configuration and delivered electronically for installation.
• Connection Hardware - USB and vehicle interface connections used to transfer files and communicate with the truck.
• Tuning License - Vehicle-specific licensing required to authorize supported calibration programming.
• SOTF Switching Functionality - Included with compatible Pickup tuning packages, allowing selection between supported power levels.
• Installation Guide - Instructions covering software setup, device registration, calibration transfer, and ECM programming.

A compatible bypass cable is required for 2018 models. DPF replacement pipes, EGR removal components, and other exhaust parts are not included with this standalone programmer.

Tuning & Performance

The EFI Live tuner 6.7 Cummins 2013-2018 communicates with the factory Engine Control Module through its dedicated programming interface. Custom calibrations update supported engine-management parameters, including fuel delivery, torque management, and other operating strategies.

For legally permitted off-road modifications, the installed calibration must match the vehicle's hardware configuration. Removing emissions components without corresponding programming can trigger diagnostic faults, warning lights, and reduced engine performance. Likewise, using a calibration intended for modified hardware with incompatible factory components can cause operating problems.

With the appropriate calibration and supporting hardware, potential changes include improved throttle response, additional horsepower and torque, adjusted fuel delivery, and more consistent engine operation. Actual results depend on the engine's condition, selected tune, transmission, and driving conditions.

Available Tune Levels

The 2013-2018 6.7 Cummins DEF delete tuner supports different calibration arrangements depending on body style. The listed horsepower increases are nominal values rather than guaranteed dyno measurements.

SOTF permits compatible Pickup configurations to change between available settings without performing a complete ECM reflash each time. Cab & Chassis applications use their designated calibration arrangements.

Installation

The 6.7 Cummins EFI Live delete tuner requires EFI Live software, a compatible Windows computer, and a custom calibration file matched to the truck.

1. Install the required EFI Live software on the computer.
2. Connect the AutoCal V3 through USB and prepare the device for file transfer.
3. Provide the VIN, year, model, engine, transmission, transfer case, tire size, and existing modifications.
4. Submit the AutoCal serial number when requested for calibration preparation.
5. Download the supplied tune file and transfer it to the programmer.
6. Connect the AutoCal V3 to the vehicle and follow the provided ECM programming instructions.

For 2018 trucks, the required bypass connection must be available before programming.

Custom files are generally prepared within several business days after the required information is received. The electronic flashing procedure is separate from file preparation and mechanical installation.

Experienced owners can complete supported electronic programming using the supplied instructions. Professional assistance is recommended for complex modifications or programming problems.

Ordering Information

Before purchasing, confirm the truck's exact model, engine, transmission, and Pickup or Cab & Chassis configuration. Accurate vehicle information is essential for preparing compatible custom files.

The EFI Live AutoCal V3 is shipped as a physical programmer, while custom tuning files are delivered electronically. Unlike a preloaded programmer, the AutoCal requires calibration preparation and file transfer before use.

DEFDelete advertises same- or next-business-day shipping for many stocked products. Actual delivery depends on inventory, destination, and carrier schedules. Custom file preparation may require additional business days beyond physical shipping.

Additional vehicles require appropriate EFI Live licensing and compatible calibration files. Software updates and support depend on the applicable programming platform and purchased services.

Eligible unused products may qualify for return authorization within 30 days of delivery. Custom calibrations, activated programming products, and personalized tuning services may be final sale once processing begins. Warranty assistance is available through DEFDelete under applicable product terms.
