Turn the tuning box on/off using the TDI-Tuning Mobile app. With a touch of a button you can turn your TDI-Tuning Box on, harnessing the full power capabilities of your engine. Or, you can turn it off, reverting the vehicle to stock.
With the TDI-Tuning App adjusting the power output is easy. Simply connect your phone to the TDI-Tuning Box and toggle between the 7 power modes at your disposal. Mode 1 offers the least amount of power, and, is commonly used for fuel saving reasons. Mode 7 is the biggest power increase you have on offer, use it for maximum power!
The TDI-Tuning Box comes built in with a 30 second warm up timer. This means the map file will not begin to run until 30 seconds after your engine is turned on. This is to protect your engine, primarily for cold engine starts. If you would like to increase, or decrease this map timer, you can adjust it using the TDI-Tuning App.
Activate ‘Discreet Mode’ on the mobile app to turn off the LED lights on the TDI-Tuning Box. All lights will be turned off, putting the tuning box into ‘Discreet Mode’. You can use this mode if you are trying to conceal the tuning box from casual inspection in the engine bay.
