GIAC has produced the highest quality performance software for VW ® vehicles for longer than most other tuners have been in existence. In fact, all GIAC calibrations for VAG cars , whether for a Golf ®, GTI ®, Jetta ®, GLI ®, Passat ®, CC ®, Tiguan ®, or Toureg ®, reflects the knowledge and rigorous test methodology we have developed over the last 23 years. GIAC even designs and develops, in house, software and hardware tools for reading and writing vehicle controllers, for creating and compiling vehicle calibrations, and for vehicle parameter logging. We succeed with these cars year after year because we have skills, knowledge and resources to get it right.
GIAC makes a variety of programs for almost every Volkswagen made from 1991 to present. Our in depth understanding of the controllers used in these cars allows us to add functionality to many platforms not found with other after market ' tuners '. GIAC map switching gives customers the ability to change performance settings in their vehicle with out flashing the car. A map 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.
All software performance programs feature a full recalibration for all driving conditions, which we can replicate at our test facility in Rancho Santa Margarita, CA. On our four wheel load bearing dyno we can run emulators, scopes, serial diagnostic tools and air/fuel meters on a car while we simulate driving it up and down hills, blast through a quarter mile race, or just run simple power pulls.
