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*
| Note |
|---|
A battery tender is highly recommended during flashing. Do not attempt to flash your vehicle if your battery life seem low or you battery power errors on the dash. An insufficient charge can lead to a failed flash! |

Since all CAN traffic is silenced it is wise to also disconnect or power down any ancillary CAN devices which may be hooked up. e.g. radar detectors, logger dashes, etc… |
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
The console (2) will now display information as the flash process progresses.
As the vehicle enters the proper flash state all CAN BUS traffic will stop and modules will shut down.
You may see some communication errors regarding certain modules displayed while gaining security access, this is normal.
Once access is granted the flashing procedure will commence and a completion percentage will update in real time.
As the flash is wrapping up you may again see some communication issues with certain modules, again this is normal.
When the flash routine is finalizing modules will come back online and alarms may once again sound. This is normal.
When prompted cycle the key off and on and click ok.
The flash is now successful and you’re all set! See special precautions at the end of this section for other important data.

FUEL GAUGE ERROR: It’s possible that the fuel gauge may display an error after flashing, particularly cars that are low on fuel. Normally, this will go away after a drive cycle. Some cars may require you to refill your fuel if the error doesn’t go away. Make sure to fill it up all the way and not partially! |
| Warning |
|---|
It’s possible for the PAS, ACC, Drivelights, TPMS, steering wheel, or other systems to show errors after the flash process. There is nothing to be alarmed about. You can start by performing a “Clear Faults” action via M-Tuner. Driving around the car for a few miles and insuring full lock to lock with the steering wheel can help clear these faults as well. They just need some time to reset and relearn. |
