Step 3. Flashing Your ECU and Auto-Licensing your M-Tuner Software

*During the flash process, the vehicle must be in the on position but the engine off and not running*

...

1. Flashing is a straight forward process that can take between 90 seconds to 6 minutes depending on the file type. Simple on screen prompts guide you through the process.

2. Open M-Tuner and connect the OBD M-Engineering dongle to your PC via the included USB cable. The other end connects to your vehicle via the OBDII port. If you have a stable connection the “Flash ECU” button (1) will now be in bold and no longer grayed out.

3. Turn the vehicle to the on position but do not start the engine. A simple way to know you’re at the right point is if the tach is showing but the engine is not running. This state can be reached simply by pressing the start/stop button with your foot off of the brake pedal.

4. Click “Flash ECU.” (1) A directory will appear. Select the file you’d like to flash and open it.

   1. A battery tender is highly recommend, particularly if flashing a M-Tuner(F) file.

5. After you select your (F) file to flash on the car, you will be prompted to enter in your Customer Name for the license. You can simply put whatever you like in the box such as your full name and the year/make/model of the car. Once this step is complete this allows you to gain full control of reading and clearing faults as well as datalogging and you won’t need to license again.

Going Back To Stock / Uninstalling Your Tune

...

Going back to stock is just as easy as applying the tune to your car. Once you are returned to stock, you can visit the dealership without any worry. Your uninstall file will verify and apply your original CALID and CVN.

• Select “Flash ECU” on M-Tuner

  • Instead of using your tune file, choose your “Uninstall” file

• Follow the prompts on the screen, the flash process will take about 5 minutes.

Flashing Process

1. The console (2) will now display information as the flash process progresses.

   1. As the vehicle enters the proper flash state all CAN BUS traffic will stop and modules will shut down.

2. You may see some communication errors regarding certain modules displayed while gaining security access, this is normal.

3. Once access is granted the flashing procedure will commence and a completion percentage will update in real time.

4. As the flash is wrapping up you may again see some communication issues with certain modules, again this is normal.

5. When the flash routine is finalizing modules will come back online and alarms may once again sound. This is normal.

6. When prompted cycle the key off and on and click ok.

7. The flash is now successful and you’re all set! See special precautions at the end of this section for other important data.
