GIAC is a software engineering company with over 20 years experience tuning cars. We are known for creating "factory smooth" performance software with exceptional power and reliability. Our 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 aftermarket performance modifications.
We at GIAC are focused on designing after-market software for Porsche ®, Audi ®, VW ®, BMW ®, and Bentley ® but also have a long history of tuning many other European makes on a case-by-case basis. Accessory products include the Flashloader Software and handheld switchers, which enable remote controlled chip switching device for easy switching between multiple GIAC programs and the stock program. We also provide custom tuning services for special projects.
GIACs development team employs proprietary GIAC software and a variety of debuggers, emulators and scopes to tackle the most complex tuning problems. Our dedicated research facility in Irvine, CA houses a 4WD Mustang Dynamometer and state of the art tools for developing and testing software. Expertise in software and circuit design, combined with an understanding of embedded technology, enable us to offer a broad range of tuning solutions.
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. GIAC exists to tune cars for the way people like to drive.
