Description

We are pleased to present the GIAC Stage 1 Plus Porsche 911 Carrera 991.2 ECU upgrade (2016 - 2019) with 3.0 Turbo engine. The Porsche 911 Carrera 991.2 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. The first-time installation includes removing the ECU from the car, flashing it and then reinstalling it. It usually takes up to 2 business days for the upgrade.

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 aspired and turbo models.
