Updating your Mini Maxx V2 tuner ensures optimal performance and access to the latest features. This guide provides a step-by-step walkthrough of the Mini Maxx Update process, ensuring a smooth and successful update. This update applies only to the V2 tuner; do not attempt this process on a Mini Maxx V1.
Preparing for the Mini Maxx Update
Before you begin, gather the necessary tools:
- Windows PC: You’ll need a computer running Windows with an available USB port.
- USB Adapter or Micro-SD Card Slot: This is included with your Mini Maxx or might be built into your laptop. It’s necessary for connecting the SD card to your computer.
- SD Card: This is the SD card from your Mini Maxx tuner. It contains the software and tunes.
Mini Maxx Update: Step-by-Step Instructions
The Mini Maxx update involves four key steps: preparing the SD card, updating the SD card, updating the Mini Maxx V2 device, and finally, updating the tune on your truck.
Step 1: Preparing the SD Card
- Remove and Connect: Eject the SD card from the tuner and connect it to your Windows PC using the USB adapter.
- Verify Naming: Ensure the SD card is named precisely “MINI MAXX” without quotation marks. If using a new SD card, reformat it to FAT (not FAT32 or exFAT) and rename it accordingly.
Step 2: Updating the SD Card
- Extract Updater Software: Download the latest Mini Maxx update file and extract its contents to a folder on your computer.
- Run Updater: Open the updater software. If prompted to connect the MMV2 drive, ensure the SD card is correctly connected and restart the software.
- Update Process: The updater will download necessary files and update the SD card. Once prompted, safely eject the SD card.
Step 3: Updating the Mini Maxx V2 Tuner
- Insert SD Card: Reinsert the updated SD card into your Mini Maxx V2 tuner.
- Power On & Navigate: Turn on the tuner and navigate to the menu. Select “Update Firmware.”
- Update and Reboot: Allow the tuner to complete the update and reboot.
Step 4: Updating the Tune on Your Truck
- Connect to Truck: Connect the updated tuner to your truck’s OBD-II port. Ensure the correct vehicle is selected in the tuner. If not, change it using the “Change Vehicle” option in the menu.
- Install Download: Navigate to the menu and select “Install Download.” Follow the on-screen instructions to load the new tune file.
Important Considerations for the Mini Maxx Update
- Battery Charger: Always connect a battery charger (minimum 10 amps) to your truck while flashing the PCM. This prevents power interruptions during the critical update process.
- Troubleshooting: “Missing SD card” errors indicate an incorrect file system (use FAT). Errors about missing files usually mean incorrect file transfer to the SD card. Ensure you copy the contents within the extracted folder, not the folder itself.
Completion
After completing these steps, your Mini Maxx V2 tuner is updated. While the version number might not change due to a known bug, rest assured that the tune files are updated. Enjoy the enhanced performance and new features!
