GIAC stage 1 plus Audi Q7 4L ECU upgrade 3.0 supercharged (333 PS)

We are pleased to present the GIAC stage 1 plus Audi Q7 4L ECU upgrade (2010 - 2015) with 3.0 supercharged (333 PS). The Audi Q7 4L ECU upgrade 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. We can easily flash the ECU upgrade through the OBD-II port of your car (an installation fee is additional).

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.

To sum up, the results will vary depending upon environmental conditions, vehicle, transmission, vehicle health, operating conditions, temperatures, fuel grade, dyno type, dyno setup, and other modifications.

Hand-held flashloader switcher for the Audi Q7 4L ECU upgrade

The optional GIAC’s Flashloader Handheld Switcher allows users to switch between optional maps/modes in the ECU upgrade with the touch of a button. To clarify, it is a pocket-sized, hand-held device that plugs directly into the OBD port. Furthermore, it uses serial flashing technology and requires no additional hardware within the ECU. To use the switcher, you should select the desired mode with the touch buttons. Cycling the ignition will save the new mode to the ECU’s memory and retain its state until switched again.

Hand-held flashloader switcher maps:

• Stock mode - The ECU of the car is switched to factory settings.
• Pump mode - The upgraded map which is optimized for pump fuel.
• Race mode - It gives additional power and should only be used with high-octane fuel.
• Valet mode - It will reduce the engine output to prevent other people (valets :)) from abusing your car.

The optional switcher with different modes for your Audi Q7 4L Stage 1 Plus starts at $200 (contact us for details).
