We are pleased to present the GIAC Stage 1 Flashloader Mobile device ECU tune for Audi B8.5 S4 and C7 A6 (2013-2016) with 3.0 TFSI engine.
The Flashloader Mobile (FLM) is pocket-sized, durable, and does not require a laptop or PC during the flash. Files and commands are stored on a USB memory stick, that can be customized by the end-user. The end-user can use the device as a flashing tool, 25-channel logger, or performance mode switcher, to code clearer or to some combination of each.

The ECU upgrade done by the Flashloader Mobile device replaces the standard software in your car's engine control unit without any physical modifications. In other words, the tune adjusts ignition timing, fuel delivery, boost settings, rev limiter, and/or speed limiters to optimize performance and, in some applications, fuel economy.

GIAC's understanding of vehicle controllers goes much deeper than simple table variable modification. While most "tuners" can only add and subtract from existing tables in the Engine Control Unit, we have the ability to change the functionality of the ECU at the code level, allowing for a complete calibration and even creation of new tables and functions.

GIAC map switching gives customers the ability to change performance settings in their vehicle without a visit to the shop. The switch takes a couple of seconds and can even be done while the vehicle is idling. We have tuning products for fuel quality ranging from 91 to 109 octane covering both normally aspirated and turbo models.

GIAC Flashloader Mobile device options for B8.5 S4 and C7 A6 3.0 TFSI

Flashloader Mobile device comes with Stage 1 ECU upgrade or pump mode as GIAC called it. The FLM device allows users to switch between optional maps/modes in the ECU upgrade with the touch of a button. Pump mode is an upgraded map that is optimized for pump fuel. This mode can be used with 91 octane fuel compatible. For optimum results use 93 octane fuel. There are a few options which could be added to the pump mode:

  • Race Gas Mode - for an additional $200. It gives additional power and should only be used with the high-octane fuel.
  • Stock Power Mode - for an additional $50. The ECU of the car is switched to factory settings.
  • Valet Power Mode - for an additional $50. It will reduce the engine output to prevent other people (valets :)) from abusing your car.
  • Transmission Flash - for an additional $650. This flash allows the transmission to hold higher torque levels with faster acceleration and quicker shifts.

If you would like to add any of the additional options, you can write that in the "Order Notes" at the Checkout or you can send us an email at or use any of the forms here.


  • This program increases power and torque performance to provide a completely different driving experience under all conditions.
  • More Boost
  • Optimized fuel and timing
  • Increased torque limits
