EFI Live AutoCal V3 DPF Delete Tuner | Ram Cummins 6.7L | 2019-2021

Description

What’s Included

Supported switchable packages include the matching power-selection switch. RAM 2019–2021 applications also require the correct security gateway bypass cable. Exhaust replacement parts and EGR removal hardware are separate from the programmer.

Vehicle Compatibility

• Years: 2019, 2020, and 2021.
• Make: RAM, commonly searched as Dodge RAM.
• Engine: 6.7L Cummins turbo diesel.
• Pickup models: RAM 2500 and 3500.
• Cab & Chassis: Requires a dedicated calibration; pickup files and power settings do not apply automatically.
• Transmission: Provide the installed transmission type when ordering.
• Connection: A compatible bypass cable is required for these model years.
• Application: Off-road and competition use only.

Your model, controller software, and modifications determine the supported calibration. Switchable tuning requires a compatible operating system and matching file; support must be checked for the specific vehicle, including 2021 applications.

How work?

The EFI Live AutoCal V3 tuner for 6.7 Cummins 2019, 2020, 2021 transfers a custom calibration from the handheld device to the engine controller. The file adjusts engine operation and the software functions associated with DPF, DEF, and EGR equipment for the intended off-road configuration. You load the supplied files through EFILive software, connect the AutoCal to the truck, and follow the programming prompts. Physical emissions removal requires separate hardware, while the calibration is designed to match those changes.

Features

An EFI Live tuner 6.7 Cummins 2019-2021 package combines custom programming with diagnostic access and data logging. Calibrated files account for the vehicle information supplied during ordering rather than using one universal tune for every truck. Compatible CSP configurations support power selection without repeating the full flash procedure. The AutoCal can be disconnected after programming and reconnected for diagnostics, logging, or supported file changes.

Tuning & Settings

The two pickup packages below have different engine calibrations. Adding transmission tuning to an existing file does not automatically convert it to the other horsepower schedule.

Figures describe advertised increases over factory output. Actual power and torque depend on vehicle condition, supporting modifications, and operating conditions. A stock-power delete calibration retains the original power target while changing the relevant emissions settings.

Choose a conservative setting for regular loaded operation. Higher power levels do not replace drivetrain upgrades or maintenance.

Key Benefits

Custom vehicle setup. Files account for your truck’s specifications and reported modifications.

Flexible pickup packages. Choose engine-only tuning or an applicable engine and transmission package.

Supported power switching. Compatible CSP configurations provide convenient level selection.

Diagnostic functions. Read trouble codes and record data to investigate operating problems.

Reusable hardware. Additional supported vehicles require their own files and licensing.

Installation Information

Setting up an EFI Live tuner for 6.7 Cummins requires a compatible computer, EFILive software, USB access, the vehicle cable, and the correct bypass hardware. Basic hand tools may be needed for cable and switch installation.

After delivery, submit the AutoCal serial number, VIN, year, model, transmission, drive type, fuel-tank configuration, and modifications, including any CCV changes. Load the assigned files onto the device and follow the supplied instructions while maintaining stable battery voltage. File preparation and shipping are separate from ECU programming time.

This process helps optimize the calibration for the actual vehicle and enhance drivability within the selected package.
