GIAC Performance Tuning


Tuning is an art. To tune for optimal performance is to tune for a careful combination of speed, strength, and agility that varies as driver tastes vary. Software engineering firm GIAC has 15 years experience tuning cars, and is known for creating “factory smooth” performance software with exceptional power and reliability.

How does tuning work? GIAC software replaces the standard software in your car’s engine control unit. It is programmed to adjust ignition timing, fuel delivery, fuel metering, boost settings, rev limiters, and/or speed limiters to optimize performance and, in some applications, fuel economy. Performance-tuned programs are designed to dramatically increase torque and HP without sacrificing smooth drivability. Many programs are also created to accommodate numerous after market performance modifications.

GIAC develops its software in a dedicated research facility housing a 4WD dynamometer and state of the art software test tools. Expertise in software and circuit design, combined with an understanding of embedded technology, enable GIAC to offer a broad range of tuning solutions (see sidebar).

Now in Edmonton… Eurasia Automotive is Northern Alberta’s authorized distributor for GIAC, meaning that you can now have GIAC software installed in your vehicle without the hassle of removing your ECU and shipping it to the United States.
