Updating your H&S Performance Mini Maxx V2 is crucial for optimal performance. This guide provides a step-by-step walkthrough of the update process, ensuring a smooth and successful upgrade. This update applies only to the V2 tuner; do not attempt this process on a Mini Maxx V1.
Preparing for the H&S Performance 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 necessary to connect the SD card from your tuner to the PC. Most laptops have built-in micro-SD card slots, while desktops may require a USB adapter.
- Mini Maxx V2 SD Card: This card contains the current software and tunes for your tuner.
Updating Your Mini Maxx V2: A Step-by-Step Guide
The update process involves several key steps:
Step 1: Preparing the SD Card
- Remove and Connect: Eject the SD card from your Mini Maxx V2 and connect it to your Windows PC using the USB adapter or micro-SD card slot.
- Verify Naming: Ensure the SD card is named precisely “MINI MAXX” without quotation marks. Important: 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:
- Run Updater Software: Open the updater software. If you encounter an error message about connecting the MMV2 drive, double-check the SD card connection and restart the software.
- Update Process: Allow the updater to download the required 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.
- Initiate Firmware Update: Power on the tuner, navigate to the Menu, scroll down, and select “Update Firmware”.
- Reboot: Let the tuner complete the update process and reboot.
Step 4: Updating the Tune on Your Truck
- Connect to Vehicle: Connect the updated Mini Maxx V2 to your truck’s OBD-II port. Ensure the correct vehicle is selected. If not, change it using the “Change Vehicle” option in the menu.
- Reflash PCM: Enter the menu and select “Install Download” to reflash your truck’s PCM (Powertrain Control Module).
- Follow Prompts: Carefully follow the on-screen instructions to load the new tune file.
Important Considerations for the H&S Performance Update
- Battery Charger: Always connect a battery charger capable of supplying at least 10 amps during the PCM flashing process. This prevents voltage drops that could interrupt the update and potentially damage the PCM.
- Troubleshooting: If you encounter a “missing SD card” error, verify the file system is FAT. A “missing file” error indicates an issue with copying files to the SD card; ensure you copied the contents within the extracted folder, not the folder itself.
- Version Number: Due to a known bug, the version number may not change after the update. This will be addressed in future updates.
Completing the H&S Performance Update
Once you’ve followed these steps, your H&S Performance Mini Maxx V2 should be successfully updated. Enjoy the enhanced performance and features!
