GIAC was the first company in the world to flash the Bentley ® Continental GT ® through the OBD port, back in early 2005. A solder in version of the performance chip was actually released previous year, but GIAC felt that replacing the soldering iron with the flash cable added a lot of value for the average Continental GT ® customer.
The GIAC product offering for the Bentley ® Continental GT ®, CGT ®, and Flying Spur ®, may include up to five settings (OEM, Performance, Race Gas Perfomance, Valet, and Immobilizer), a privacy firewall and the Flashloader Handheld device for switching the settings. As the Continental GT ® relies on two controllers for engine management, synchronizing them for the software flash and for the program switching was definitely an impressive task. Currently the GIAC performance program for the Continental GT ® produces 100-114 hp and 120-130 ft-lbs of torque 91-93 octane dependent. Boost is increased from .5 to .9 bar in the mid range and from .5 to .8 in the high rpms. During development knock, knock correction, air fuel, boost, waste gate duty cycle and many other parameters were closely monitored as with all GIAC performance program development.
