The Mini Maxx V2 is a powerful tuner, but it is not compatible with every diesel truck. Some models may face PCM software restrictions, emissions system incompatibilities, or hardware mismatches. This guide will break down supported models, incompatibilities, and solutions to potential issues, ensuring you are fully prepared before installation.
Why Is Compatibility Important?
Before installing the Mini Maxx V2, ensuring compatibility is crucial. If the truck tunes are not compatible with your truck, it may result in failed tuning, power loss, or even damage to your vehicle’s electronic systems.
Additionally, certain truck models have PCM software versions that may not align with Mini Maxx V2. For example, some RAM and Ford models may receive "Part Number Not Supported" errors or error codes like P24C6, P04E3, indicating incompatibility. These codes often mean your truck requires a software update or a specific firmware version for the tuner to work correctly.
Common Compatibility Issues:
· P24C6 / P24DA Errors – Update the Mini Maxx V2 firmware to the latest version. If the issue persists, check for official patch files from the manufacturer.
· P04E3 Code on 2016 Powerstroke – This is caused by a missing PCV sensor. Download the fix file from the official website, extract the "MGGDT.IT1" file, and copy it to the SD card's "FORD" folder. Then, update the tuner firmware and reinstall the tune.
✅ Solution: Always check your PCM software version and update Mini Maxx V2 to the latest firmware before installation.
Which Vehicles Are Not Supported by Mini Maxx V2?
Even though Mini Maxx V2 supports many diesel trucks, some vehicles are not compatible due to PCM versions, emissions systems, or hardware limitations.
Incompatible Vehicles and Common Issues
❌ The following vehicles are NOT supported by Mini Maxx V2:
· 2010-2012 RAM 4500/5500 (completely unsupported)
· 2018+ RAM (PCM part numbers starting with letters are not supported)

Key Factors Affecting Mini Maxx V2 Compatibility
PCM Software Version Requirements
The PCM (Powertrain Control Module) is the core electronic unit in your truck, and Mini Maxx V2 needs to be compatible with its software for proper functionality.
Common Issues:
· 2018+ RAM: If the PCM software version's part number starts with a letter, Mini Maxx V2 may not work.
· 2011+ Ford Powerstroke: Certain PCM versions may trigger P24C6 or P24DA errors. This requires updating the Mini Maxx V2 firmware to a compatible version.
✅ How to Check Your PCM Version:
1. Go to your vehicle’s diagnostics menu and locate the PCM software version.
2. Compare your PCM version with Mini Maxx V2’s official support list.
3. If your PCM version is unsupported, check for software updates or consider replacing the PCM with a compatible version.
Conclusion: How to Ensure Mini Maxx V2 Works Perfectly with Your Truck?
Before installing Mini Maxx V2, checking compatibility is crucial. If the tuner does not match your truck’s specifications, it can lead to tuning failures, power loss, or PCM errors. This guide has outlined essential steps to verify compatibility and avoid common pitfalls.
