Mini Maxx V2 Tuner Core Advantages

4-in-1 DPF, EGR, DEF, and SCR Delete Tuning

One device reprograms the ECM to stop looking for removed emissions hardware. The V2 generation adds full DEF urea and SCR shutdown that older tuners leave behind, so a deleted truck runs without regen cycles or dash warnings. Code suppression means fewer shop visits for phantom errors.

Real-Time Digital Monitoring

The HDMI-linked screen tracks 20-plus parameters, including EGT, boost, transmission temp and coolant. Automatic safety backdown protects the engine if exhaust gas temp or boost climbs too high under load.

DTC Management

The tuner clears existing diagnostic trouble codes and prevents new ones after the delete, including P2459 and P2463 for DPF and EGR circuit faults. You keep a clean dashboard without constant warning lights. Confirm the full code list for your platform with the supplier before publishing.

Customizable Power and Shift-On-The-Fly

Adjust speed limiters, tire-size recalibration, and SOTF power levels from the cab. Drop from a 300 HP performance tune to a calm tow tune without leaving the seat on supported platforms. Shift-on-the-fly uses the included switch where provided; some kits ship the SOTF switch as a separate accessory, so confirm what your bundle includes.

Fuel Flexibility and Updateable Design

The V2 supports ULSD or high-sulfur diesel for broader fuel use after the delete. Firmware and tune updates load through the Micro SD to USB adapter, so the device stays current as truck tech changes.

Ideal For

  • Diesel enthusiasts after a power boost: shift-on-the-fly tunes up to 300 HP suit weekend pulls and spirited driving on closed courses.
  • Professional haulers and towing pros: a tame tow tune keeps temps down under load while preserving drivability.
  • Off-road racers and competitors: built for competition and closed-course use where emissions hardware comes off.
  • Multi-fleet shops and households: one tuner serves Cummins, Powerstroke and Duramax trucks instead of three separate devices.
  • Owners of 2017-2021 trucks: the V2 covers newer Ram and Powerstroke years that earlier tuners cannot reach.

Core Feature Badges

  • DPF, EGR, DEF and SCR 4-in-1 Delete-Capable Tuning: reprograms the ECM to stop looking for removed emissions hardware, including the DEF urea injection and SCR catalyst.
  • Shift-On-The-Fly Ready: change Tow, Street, or Performance power without leaving the seat on supported platforms.
  • Real-Time Digital Gauges: watch EGT, boost, transmission temp, and coolant live on the HDMI-linked screen.
  • Pre-Loaded Race Tunes: factory-matched delete tunes are installed at the warehouse, so the unit is ready the day it arrives.

What Mini Maxx V2 Delete Tuner Shuts Off

Mini Maxx V2 reprograms the ECM so the truck stops looking for missing emissions hardware. The table below shows which systems the tune handles in software, including the DEF and SCR urea systems that the V2 generation controls.

  • DPF (Diesel Particulate Filter): Disabled in software
  • EGR (Exhaust Gas Recirculation): Disabled in software
  • DEF (Diesel Exhaust Fluid / Urea Injection): Disabled in software
  • SCR (Selective Catalytic Reduction): Disabled in software
  • CAT (Catalytic Converter): Disabled in software
  • DOC (Diesel Oxidation Catalyst): Disabled in software
  • EGT (Exhaust Gas Temp Sensor Monitoring): Monitored, safety backdown active
  • DTC (Diagnostic Trouble Codes): Clears and prevents delete-related codes such as P2459 and P2463

Note: The DPF, EGR, DEF, and SCR hardware still require physical removal for an off-road delete. The tune handles programming, not the wrench work. Once the hardware is gone, it also clears related codes such as P2459 and P2463 so the dash stays clean. Confirm the exact code list for your platform with the supplier before publishing.

Technical Requirements & Warnings

  • SGW Bypass Cable (2018–2021 Ram 6.7L Cummins): Must install Security Gateway bypass cable to complete tuning.
  • PCM Part Number (2018–2021 Ram 6.7L Cummins): PCM part number cannot start with a letter. Verify before ordering.
  • 20 PSI Boost Limit (2019–2021 Ram 6.7L Cummins): Single-tune support only. Confirm current tune status.
  • No Boost Monitoring (2011–2016 LML Duramax): MAP/Boost sensor readout is restricted on this platform.
  • Unsupported Models (Dual-tank Ram, LGH engines): Do not order for these specific configurations.

Mini Maxx V2 Tuner vs Physical Delete

A tuner changes what the truck looks for in software. It cannot remove hardware. Mini Maxx V2 disables DPF, EGR, DEF, and SCR codes so the engine runs without check engine lights or limp mode.

For an off-road delete, the DPF, EGR, and recommended DEF or SCR components must still be physically removed. The tuner does the programming, the wrench work remains the installer's job, and legal compliance is the owner's responsibility.

Mini Maxx V2 vs V1 Comparison

Mini Maxx V2 builds on the original V1 with full DEF and SCR (urea) shutdown, a larger screen, and USB-C or MicroSD fast updates. The V2 reaches 2017-2021 Ram and Powerstroke trucks that the V1 does not cover, while the V1 stays focused on 2007-2016 multi-platform use. Verify the exact V1 and V2 capability split with the supplier before you publish or purchase.

Mini Maxx V2 Tuner vs EZ Lynk Comparison

Buyers often weigh Mini Maxx V2 against the EZ Lynk AutoAgent. Both target deleted diesel trucks, but they work differently. The V2 is a standalone unit with its own screen and offline SD tunes; EZ Lynk is a wireless OBD module paired with a phone or tablet.

Pick the V2 for set-and-forget offline use, and EZ Lynk when you want cloud-pushed custom tunes. Verify current EZ Lynk specs with the manufacturer, and remember both are off-road and competition only.

Mini Maxx V2

  • Form Factor: Standalone physical display
  • Tuning Logic: Pre-loaded SD tunes, offline
  • Installation: Moderate (requires routing the OBD cable)
  • Connectivity: No internet needed to flash
  • Best For: Offline or remote use, set-and-forget setup

EZ Lynk AutoAgent

  • Form Factor: Wireless OBD module paired with smartphone or tablet
  • Tuning Logic: Cloud-pushed custom tunes
  • Installation: Ultra-low, plug-and-play
  • Connectivity: Requires mobile app and cloud connection
  • Best For: Remote custom tuning and cloud-based management

Mini Maxx V2 Tuner Fuel Economy

Owners running a full off-road delete with Mini Maxx V2 frequently report fuel-economy gains, and some industry sources cite up to about 5 MPG.

Results vary by engine, tune level, and driving conditions, and are not a guarantee. Treat any MPG figure as an owner-reported range, not a specification.

Upgrade Your Mini Maxx V2 DPF Delete Tuning

One device covers your whole diesel fleet. Mini Maxx V2 reprograms the ECM to stop emissions codes, so a truck with a removed DPF, EGR, DEF, and SCR runs clean without a dashboard full of warnings. Shift-on-the-fly lets you drop from 300 HP down to a tame tow tune without leaving the seat on supported platforms.

This tuner is built for off-road and competition use only. Pair it with the correct physical delete hardware for your platform, then load the matching tune. All use is the owner's legal responsibility, and the wrench work of removing emissions parts is separate from the programming this device performs.

Recommended 6.7 Cummins, Powerstroke and Duramax Upgrades

  1. 6.7 Cummins and 6.7 Powerstroke DPF Delete Pipes: A DPF delete race pipe pairs Mini Maxx V2 with the right exhaust hardware so the truck runs code-free after the DPF comes off.
  2. EGR and CCV Block-Off Kits: Match the tuner to an EGR delete kit and CCV reroute so the DPF, EGR and crankcase vapors are gone together with no phantom codes.
  3. Tuner Harness Plug Kit: After the sensors are unplugged, seal each unused factory connector with a tuner harness plug kit for a weatherproof, corrosion-free install.
  4. Older Fleet Coverage: For 2007-2016-only trucks, Mini Maxx V1 tuner covers the same Cummins, Powerstroke and Duramax platforms at a lower entry cost.

FAQs about Mini Maxx V2 Tuner

Can I use Mini Maxx V2 as a DPF delete tuner for a 6.7 Cummins or 6.7 Powerstroke?

Yes. Mini Maxx V2 is engineered to work as a complete DPF delete tuner for a 6.7 Cummins and a 6.7 Powerstroke, disabling DPF, EGR, DEF, and SCR so the truck runs without regen cycles or dash warnings. This is for off-road and competition use only, where the emissions hardware has been physically removed.

Which trucks does Mini Maxx V2 tuner support?

Mini Maxx V2 tuner supports 2007-2021 diesel trucks across three platforms. Cummins covers 6.7L Ram from 2007.5 through 2021. Powerstroke covers 6.4L (2008-2010) and 6.7L (2011-2019). Duramax covers 6.6L LMM (2007.5-2010) and LML (2011-2016). It is not compatible with dual-fuel-tank Ram trucks, LGH engines, or any gasoline platform.

What emissions systems does Mini Maxx V2 shut off, including DEF and SCR?

Mini Maxx V2 disables DPF, EGR, DEF, and SCR in software, plus the related CAT, DOC and sensor codes. The V2 generation adds full DEF urea injection and SCR catalyst shutdown that earlier tuners leave behind. The hardware for each system still has to come off physically for an off-road delete; the tuner performs the programming side only.

How much horsepower and torque can I gain?

Power varies by model. The 6.4L Powerstroke reaches up to 300 HP and roughly 500 lb-ft of torque on the top performance tune. Cummins and Duramax gains vary by year and tune level. All figures are estimates that depend on vehicle condition and the physical delete hardware installed.

Is Mini Maxx V2 tuner legal for road use?

No. This tuner is for off-road and competition use only. Federal law prohibits disabling emissions systems on public roads, and using it on public roads may bring fines or penalties. All use is the owner's legal responsibility, and compliance with local regulations must be confirmed before installation.

What is included in Mini Maxx V2 tuner package?

The kit includes Mini Maxx V2 Tuner unit with pre-loaded multi-platform delete tunes, an OBD connection box with HDMI cable, a power adapter and fuse tap, a Micro SD to USB adapter for updates, a tuner mount with USB cable, and the full installation hardware kit. The included mount keeps the screen in view while you drive.

Can I monitor engine parameters in real time?

Yes. The tuner displays 20-plus real-time metrics on its HDMI-linked color screen, including exhaust gas temperature, boost pressure, transmission temperature and coolant temperature. The safety backdown cuts power if EGT or boost passes the safe limit, so you can watch the motor while you drive.

How do I disable the EGR and DPF systems?

Mini Maxx V2 reprograms the ECM to disable emissions monitoring, including DPF, EGR, DEF and SCR, so the truck runs without check engine lights or limp mode. For an off-road delete, the DPF, EGR and recommended DEF or SCR components must still be physically removed. The tuner handles the software side, not the wrench work, and legal compliance is the owner's responsibility.

Why does my 2018-2021 Ram Cummins need an SGW bypass cable?

Your 2018-2021 Ram 6.7L Cummins needs an SGW bypass cable because its Security Gateway blocks aftermarket programming, so the tune cannot write without one. The PCM part number must also not start with a letter, and the 2019-2021 trucks are limited to a single 20 PSI boost tune for now.

Confirm these details against your VIN before ordering, because they are hardware-driven limits rather than defects.

What warranty and support are offered?

Mini Maxx V2 tuner includes 1 year of technical support via email and phone. Orders ship from our U.S. warehouse hubs in CA, TX, OH, and NJ with a 1-year warranty and a 45-day free return. Mini Maxx reviews from working fleets back its racing-proven reliability since the line launched. Confirm warranty details with your seller before purchase.

Mini Maxx V2 Tuner Installation Guide

Mini Maxx V2 is a plug-and-play OBD-II device. Mini Maxx V2 Installation Guide and Mini Maxx V2 Updater are listed in the product resources for reference.

Before you begin, confirm the truck is a 2007-2021 diesel and that you have the physical delete hardware ready. For 2018-2021 Ram Cummins, have the SGW bypass cable on hand, because the tune will not write without it.

Step 1: Park on a level surface, set the parking brake, and turn the key to the run position without starting the engine. Let the truck sit for a full minute so the modules sleep.

Step 2: Locate the OBD-II port under the dash. On 2018-2021 Ram Cummins, install the SGW bypass cable at the security gateway first, then plug the tuner OBD box into the bypass.

Step 3: Connect the OBD connection box to the tuner with the HDMI cable, then attach the power adapter and fuse tap to a live circuit if your kit requires it.

Step 4: Power on the tuner and pick your platform and year. The pre-loaded race tune for your engine appears automatically; select Tow, Street, or Performance.

Step 5: Follow the on-screen prompts to write the tune. Do not interrupt power during the flash. The tuner clears existing DTCs and prevents new emissions codes as it finishes.

Step 6: Mount the screen with the included suction cup mount, start the truck, and confirm no check engine light returns. If a light stays on, recheck the bypass cable or the delete hardware before driving.

Step 7: Update firmware anytime through the Micro SD to USB adapter using the official updater. Keep the SD card safe so future tune updates load without a PC.

This guide covers the programming side only. The DPF, EGR, DEF, and SCR parts must be physically removed offline for an off-road delete. All use is off-road and for competition only, and legal compliance is the owner's responsibility.
