Black Maxx Update Instructions: 6.6L LMM Duramax
NOTE: Do NOT use the supplied USB cable to perform updates on your Black Maxx! When updating, ONLY USE the SD Card reader that was supplied with your tuning device.
Do NOT format or delete files from your SD Card unless instructed to do so by an H&S representative!!! Doing so can remove necessary information that your H&S unit needs to function correctly. If you need to download the entire SD card as it comes from H&S CLICK HERE
With the Black Maxx plugged into your vehicle or a computer, select ‘Menu’ from the gauge screen. From the Main Menu, scroll down and select ‘Show Settings’. Once inside the Show Settings Menu, you will be able to see Vehicle Information and System Information. Under the “System Info” section you should see something similar to “Version: SW-1.00.9 TV-6.7.9″. The “TV” number represents the Tune Version that is currently loaded on the vehicle. If the Version on the website is higher than the Tune Version shown on the Black Maxx, then updating is recommended. If your Black Maxx does NOT show a “TV” number AT ALL, then updating is recommended.
1 Once you have decided that you need to update, click the Downloads>Black Maxx Downloads Link, select your vehicle then click on the Latest Software Link. You will be prompted to either Save or Open, you must choose SAVE. It is good practice to save the file somewhere that you will easily find it later, like on the Desktop. Some computers will automatically save downloaded files to “My Documents/Downloads”, so check there if your computer does not ask you where you would like to save the file.
2 After file is saved, you will need to extract it. All files on the H&S Website are “Compressed” or “Zipped” to save time and space so we must Extract (“Un-compress” or “Un-Zip”) the files in order to make them usable. Most commonly you can go to where you downloaded the compressed file and RIGHT click the file. A menu should appear and within this menu should be an “Extract All” option. Follow the onscreen instructions in order to get the files extracted correctly.
If you have problems extracting the files, you may need to use 7-zip to extract them. 7-zip found HERE.
3 Now that the files are correctly extracted, they need to be transferred onto the Black Maxx SD Card. The easiest way to do this is by Copy and Paste. Open up the recently extracted folder *WITHOUT THE ZIPPER*, (you may have to open two folders before you can see the individual files) and you should see numerous files. You will need to select, or highlight, all of the files in that folder. To do this, hold down the “Ctrl” button and press “A”. Another way to do this is by clicking “Edit” at the top menu and selecting “Select All”. Next, RIGHT click your mouse over any one of the files that are highlighted and select “Copy”. Another way to copy the files is by holding the “Ctrl” button and pressing “C”.
4 After you have copied the files, go to the contents of the Black Maxx SD Card (usually named “Black Maxx”), and Paste the files into it by RIGHT clicking inside the Black Maxx and selecting “Paste” or by holding “Ctrl” and pressing “P”. Your computer should give some warnings that files already exist, and you need to make sure and REPLACE the existing files with the new ones.
Now you can re-insert the SD card into the Black Maxx.
5 Now that all the new software is installed on the SD card, you can remove the SD card from your computer and return to your truck. Install the SD card back into the Black Maxx. Make sure the SD card “clicks” to ensure proper connection.
6 Turn the key to the RUN position, but do not start the vehicle. While at the main screen, press the top left button labeled “Menu”. Scroll to the bottom and select “Update Black Maxx Firmware”. The Black Maxx will transfer the needed files, then the screen will darken and lights will flash. The Black Maxx will then re-boot to the main screen. You may lose some of your saved settings on the Black Maxx, they will need to be reset to your desired settings. (defuel, colors, gauges, etc.)
7 Now you will need to re-install the download on the truck. Hit the top left “Menu” button, then “Install Download” (you may need to scroll UP to see “Install Download”). Select “Change Settings” or “Change Tuning”, and the Black Maxx will install any updated tuning onto the truck’s computer.
8 For automatic transmission trucks it is advised to re-train your transmission. The GM Allison transmission is constantly “learning” and adapting to your specific driving style. This re-train procedure gives a good baseline for the adaptive learning. Your transmission will eventually learn over time on its own, but the re-train process is highly recommended to help speed up the learning process.
After the download is complete, hit “Menu” from the start up screen. Use the down arrow on the right side of the unit to scroll down to “Reset Transmission”. Press the button next to Reset Transmission to activate the relearn process.
During this transmission re-learn process you may experience “harsh” shifting, “missed” shifts, or erratic results. Continue the process, this is normal.
