GIAC Stage Xplus Bentley Continental GT3R ECU upgrade
$2,400.00
The Bentley Continental GT3R ECU upgrade adds horsepower, torque, and better throttle response throughout the power band.
Description
We are pleased to present the GIAC Stage Xplus Bentley Continental GT3R ECU upgrade. It is for only for a few years in the 2nd generation (2012 - Present) model with the 4.0L V8 Turbo engine. The Bentley Continental GT3R ECU upgrade replaces the standard software in your car's engine control unit (ECU). There are no physical modifications to the ECU. In other words, the tune adjusts ignition timing, fuel delivery, boost settings, rev limiter and/or speed limiters to optimize performance. In some cases, fuel economy can be improved too. The process takes around 3 business days and there is an additional labor fee as the ECU needs to be removed from the car. An additional fee applies.
GIAC's understanding of vehicle controllers goes much deeper than simple table variable modification. 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 the creation of new tables and functions.
