Flash ECU - This button is how you activate the flash routine to change files on your ECU over OBDII
Console - This is where important flashing information is displayed in real time. Map Notes, completion percentage, etc, will be displayed here during the flash process.
Profile - Profile affords multiple different logging profiles which can be customized to cater to specific systems we are focusing on trying to improve. Every M-Tuner will come with a “General” logging profile.

Actuators - This is where you will find actuators to turn on and off certain functions. Such as turning on and off the fuel pump to pump out fuel, or turning radiator fans on to help cool the car down in the pits after a long track session.
Logging Rate & License - Your current logging rate is displayed in this panel. When logging your sample rate is displayed in Hz. The License portion displays who this particular version of M-Tuner is licensed to. The license allows your vehicle to communicate with M-Tuner.
