Mini Maxx V2 DEF Delete Tuner | Ram Cummins 6.7L | 2013-2018

2013-2018 RAM 6.7 Cummins DEF delete tuner

The 2013, 2014, 2015, 2016, 2017, 2018 6.7 Cummins DEF delete tuner is a handheld engine programmer with preloaded calibrations for compatible Ram diesel trucks. The Mini Maxx V2 combines ECM programming, real-time engine monitoring, and diagnostic functions in a single device with an integrated display.

Designed for supported Ram 2500, 3500, 4500, and 5500 configurations, the Mini Maxx V2 tuner 6.7 Cummins 2013-2018 supports specialized modifications involving DPF, DEF/SCR, and EGR emissions systems where legally permitted. It offers multiple horsepower settings, engine monitoring, and calibration options for different driving requirements without requiring separately delivered custom tune files.

Why Choose

• Preloaded tuning: The programmer includes ready-to-use engine calibrations without requiring custom file delivery for standard supported applications.
• Four power settings: Choose between Stock, +40, +80, and +120 HP through the device menu.
• Integrated monitoring: View engine parameters, including supported temperatures, boost pressure, and other performance data.
• Diagnostic capabilities: Read and clear supported diagnostic trouble codes directly from the tuner.
• Standalone operation: Programming and monitoring are handled by the device without requiring a smartphone or cloud-based tuning subscription.

Vehicle Compatibility

The DEF delete tuner for RAM 6.7 Cummins must match the vehicle's model year, body style, and transmission. Cab & Chassis trucks with dual fuel tanks are excluded, even when equipped with the 6.7L Cummins engine.

Components

• Mini Maxx V2 Programmer - Handheld electronic tuning device with an integrated display for ECM programming, vehicle monitoring, and diagnostic functions.
• Preloaded Tune Files - Built-in engine calibrations providing supported performance and emissions-related tuning options without separate file delivery.
• Vehicle Connection Hardware - Interface hardware used to connect the programmer to the truck's diagnostic system.
• Installation Guide - Instructions covering initial configuration, vehicle selection, programming, and basic device operation.

The standard tuner package does not include DPF replacement exhaust pipes, EGR removal hardware, or other mechanical components. The supplied calibrations are already loaded onto the programmer, so a separate custom tune purchase is not part of the standard installation process.

Tuning & Performance

The DEF delete tuner 6.7 Cummins 2013-2018 communicates with the factory Engine Control Module to install one of its preloaded calibrations. The programming process adjusts supported engine-management parameters, including fuel delivery, torque management, and other operating strategies.

For legally permitted off-road modifications, matching ECM calibration and exhaust hardware is essential. Removing restrictive factory emissions components without appropriate tuning can cause warning lights, fault codes, and reduced engine performance. Similarly, applying a calibration intended for modified hardware while retaining incompatible factory components can cause operating issues.

When properly configured, the Mini Maxx V2 can provide improved throttle response, increased available horsepower, more consistent torque delivery, and engine monitoring through its built-in screen. Actual fuel efficiency and performance depend on vehicle condition, selected settings, and operating conditions.

Available Tune Levels

Certain ECM calibrations in 2013+ Ram are limited to 50HP, this includes 2019-2021 models.

Stock Power +0HP, Tow +15Hp, Street +30HP, Performance +50HP

These are nominal increases over factory output, not guaranteed measured horsepower gains.

The 6.7 Cummins Mini Maxx V2 tuner does not support Shift-on-the-Fly (SOTF). Power levels are changed through the programmer's menu using the required calibration-selection procedure, rather than switching instantly while driving.

Installation

The Mini Maxx V2 includes preloaded tunes, allowing supported vehicles to be programmed without registering an online tuning account or submitting a VIN for routine custom-file preparation.

1. Confirm the truck's model year, engine, transmission, and body style.
2. Connect the programmer using its vehicle connection hardware.
3. Select the correct Ram Cummins platform in the device menu; the programmer may initially display a different vehicle platform.
4. Follow the on-screen guide to select the appropriate calibration.
5. Maintain stable battery voltage throughout the ECM programming process.
6. Complete the programming procedure before making hardware modifications that require the corresponding calibration.

The electronic setup is suitable for experienced DIY users familiar with vehicle programming. The overall installation time depends on programming, mechanical work, and any required troubleshooting.

Professional assistance is recommended for unfamiliar vehicle configurations or complicated exhaust modifications. DEFDelete can provide product-related technical support and installation guidance.

Ordering Information

Before ordering, verify your truck's year, engine, body style, and fuel tank configuration. Dual-tank Cab & Chassis models are not supported, and transmission-related features depend on the vehicle application.
