The tuner is explicitly designed for deleted trucks and does not support vehicles with active emissions systems. As such, it is not intended for use on street-legal vehicles and should be installed in accordance with local regulations.
Key Features of the Mini Maxx V2
The Mini Maxx V2 offers a variety of features that cater to performance-oriented diesel owners:
- Complete DPF Removal: The tuner allows for the complete removal of the DPF system without the need for race exhaust modifications. This includes disabling DPF-related sensors and preventing the illumination of the check engine light.
- Top Speed Limiter Adjustments: Users can adjust or remove the speed limiter to increase the maximum allowable speed of the vehicle.
- Speedometer Recalibration: The tuner supports recalibration of the speedometer for non-stock tire sizes or gear ratios.
- Full EGR System Deletion: The EGR system can be fully deleted without triggering diagnostic trouble codes (DTCs), and the tuner also offers the option to disable the EGR without removing physical components.
- DTC Read and Clear: The tuner can read and clear diagnostic trouble codes, allowing users to monitor and resolve engine issues.
- Internet-Updatable Firmware: Users can update the tuner's firmware via the included micro SD card and USB cable, ensuring compatibility with the latest engine software.
- Real-Time Monitoring: The device supports real-time monitoring of over 20 engine parameters, including boost pressure, fuel rail pressure, intake temperature, and exhaust gas temperatures. Users can view up to four parameters at once on the tuner's display.
Supported Applications and Model Compatibility
The Mini Maxx V2 is compatible with a range of diesel trucks, including models from General Motors (Duramax), Dodge (Cummins), and Ford (Powerstroke). The following table outlines the supported models, years, and features:
| Model | Year | Pickup | Cab Chassis | SOTF |
|---|---|---|---|---|
| Duramax 6.6L Sierra/Silverado (2500-5500) | 2007.5-2010 | Yes | Yes | Yes |
| Duramax 6.6L Sierra/Silverado (2500-5500) | 2011-2016 | Yes | Yes | No |
| Powerstroke 6.4L (F250-F550) | 2008-2010 | Yes | Yes | Yes |
It is important to note that certain models have limitations or exceptions. For example, the 2015 and 2016 Ford Powerstroke 6.7L models may trigger a DTC related to the crankcase ventilation detection sensor, which the tuner does not compensate for. Additionally, 2019-2021 RAM trucks currently have limited power level options, and LML GM Duramax models do not register boost levels. These issues are acknowledged in the source documentation and may require additional considerations or future firmware updates.
Installation Process
The installation of the Mini Maxx V2 involves several steps, including connecting the tuner to the vehicle's OBD port, configuring the power supply, and loading the appropriate tunes. While the source material does not provide a step-by-step installation guide, it references the availability of installation instructions and video tutorials on the manufacturer's website. Users are encouraged to consult these resources for detailed guidance.
The following general steps are implied by the source content:
- Prepare the Vehicle: Ensure that the vehicle's emissions systems (DPF, EGR, DEF) have been properly removed or disabled in accordance with the tuner's requirements.
