Description

What’s Included

Component Description
Mini Maxx V2 programmer and display A handheld tuning device with a built-in screen for programming, viewing supported engine parameters, and accessing diagnostic functions.
Preloaded delete software Includes application-specific tuning for an off-road configuration with DPF, DEF, and EGR systems disabled. Select the correct vehicle application before installation.
OBD connection hardware Connects the programmer to the truck’s diagnostic system. The 2019–2021 RAM application requires the dedicated bypass connection described below.
SD card and USB update connection Used to transfer compatible software updates. Follow the Mini Maxx V2 update instructions rather than instructions for other programmers.
Installation instructions Explain initial setup, vehicle selection, programming, and the required sequence for supporting hardware changes.

The required RAM bypass kit uses a replacement OBD box and connection cable. Select the correct RAM application and verify the bypass kit is part of your order. Exhaust replacement parts, EGR hardware, and an aftermarket EGT monitoring kit are separate purchases.

Vehicle Compatibility

  • Years: 2019, 2020, and 2021.
  • Make: RAM, also commonly searched as Dodge RAM.
  • Engine: 6.7L Cummins turbo diesel.
  • Pickup models: RAM 2500 and 3500.
  • Cab & Chassis: Supported RAM configurations require verification of the exact model and fuel-tank arrangement; dual-tank C&C applications are excluded.
  • Connection requirement: Dedicated 2018+ RAM bypass hardware.
  • PCM compatibility: Check the installed PCM software identification, particularly if the module has received replacement or updated software.
  • Application: Off-road and competition use only.

Match the year, engine, body style, and transmission before programming. Compatibility with a truck model does not mean every PCM software version is supported.

How work?

The Mini Maxx V2 tuner for 6.7 Cummins 2019, 2020, 2021 installs a preloaded engine calibration through the vehicle’s diagnostic connection and required bypass hardware. The software changes how the ECU manages the DPF, DEF, and EGR systems for the intended off-road setup. The programmer also provides access to supported monitoring and diagnostic functions through its own display. Physical emissions-system changes require separate parts and must follow the installation sequence supplied with the tuner.

Features

This RAM 6.7 Cummins tuner operates through a built-in screen, so a smartphone is unnecessary for normal programming and monitoring. Preloaded software provides a direct setup process without waiting for a separately prepared custom file. The device reads and clears supported diagnostic trouble codes and accepts compatible SD-card updates. For 2019–2021 RAM models, its single available power setting is an important application-specific limitation.

Tuning & Settings

Engine tuning

Setting or function RAM 2019–2021 configuration
Available power settings One application-specific tuning level
Multiple selectable horsepower stages Not offered for this application
Shift-on-the-fly power selection No multi-level selection with the single available tune
Boost behavior Known application issue can limit boost to approximately 20 PSI
Return to stock Available through the device’s restore function; factory hardware must match the restored calibration

The 20 PSI figure describes a known operating limitation, rather than a horsepower increase or adjustable boost target. Do not apply power figures advertised for earlier RAM models to this product.

Transmission and drivetrain settings

Item Requirement or effect
Transmission identification Match the installed transmission during vehicle setup.
Engine power selection This application uses one level; transmission selection does not create additional power stages.
Mechanical drivetrain capacity Programming does not strengthen transmission components or increase factory towing ratings.

Monitoring

Function Capability
Live gauges Displays supported vehicle data through the tuner screen.
Diagnostics Reads and clears supported trouble codes.
EGT readings Factory EGT probes are unsupported; compatible aftermarket monitoring hardware is required.

Fuel efficiency depends on load, driving habits, and vehicle condition. Use monitoring to assess operation rather than treating tuning as a guaranteed fuel-economy improvement.

Key Benefits

Preloaded programming. Start with application-specific software already supplied on the device.

Integrated display. Monitor supported engine data without using your phone as the screen.

Diagnostic access. Read trouble codes before installation and investigate warnings afterward.

Update capability. Install compatible software releases using the SD card.

Stock restoration. Restore the original software configuration when returning the vehicle to matching factory hardware.

Installation Information

Installing a delete tuner for 6.7 Cummins 2019-2021 requires the correct bypass kit, basic hand tools, and a battery charger capable of supplying at least 10 amps continuously. A computer is needed when transferring software updates, while vehicle programming uses the tuner itself.

Resolve existing emissions-related warnings while the truck remains stock. Install the tuning before changing emissions hardware, follow every ignition prompt, and maintain power throughout flashing. Choose RAM in the vehicle menu; a unit initially configured for another engine platform must be changed before use.

The tuner improves access to monitoring and diagnostics, but installation quality and vehicle condition remain essential to reliability.

FAQ

A RAM 6.7 Cummins delete tuner with preloaded software and its own display offers straightforward operation. It is best suited to buyers who understand the single-level configuration and known boost limitation for these model years.

Factory software can detect missing emissions equipment and trigger warnings or reduced-power operation. Complete programming and follow the instructed hardware sequence to keep the software and physical configuration matched.

It can read and clear supported diagnostic codes. An active fault may return, so clearing a warning does not replace diagnosis or repair.

Yes. Instructions explain how to connect and configure the Mini Maxx V2 tuner for 6.7 Cummins, install the software, and complete supporting changes. Use the guide for your exact RAM application.

Programming time depends on the PCM and the installation steps shown on screen. Allow an uninterrupted session; mounting, bypass installation, software updates, and mechanical work add separate time.

An owner comfortable with electrical connections and following programming instructions may handle device setup. A diesel shop is the appropriate choice if you need help identifying PCM compatibility, installing bypass hardware, or completing exhaust and EGR work.
