5Series.net - Forums - ▀▄ eas | NEW GIAC Stage 1 & 2 software [Handheld Switcher Avai

We are proud to announce that european auto source is your Orange County's authorized GIAC flash facility.

GIAC is a software engineering company with 17 years experience tuning cars 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 after market performance modifications.

GIAC has just announced handheld switching options for N54 powered BMWs. GIAC is the first in the world to offer a flash solution with on-the-fly selectable programs. This handheld switching technology is quick and seamless, allowing for programs to be selected even while driving (though, we don't recommend it for safety reasons). In addition to the pump 91/93 octane (95/98 RON) currently available, we will be offering a 100 octane (104 RON) option. This calibration is also compatible with methanol injection (50/50 mixture or higher, 375ml nozzle size), and is available for both stage 1 and stage 2. A stock mode is also available for purchase which reduces performance and drivability to factory levels. Finally, we will be offering a valet mode that dramatically reduces power output and throttle sensitivity so that curious attendants cannot enjoy the true power of your N54.

Power gains on our stage 1 pump gas calibration are 53 horsepower and 68 ft/lbs of torque at the wheels. Additionally, the race gas/water meth calibration gains are measured at 67 horsepower and 97 ft/lbs of torque at the wheels.

For Stage 2 Software, the calibration has the same smooth drivability of our Stage 1 N54 calibration, but takes flash software performance to a whole new level. Power gains on our pump gas calibration are 104 horsepower and 108 ft/lbs of torque at the wheels. Race gas/water meth calibration (previously referred to as Stage 2+) gains are measured at 125 horsepower and 146 ft/lbs of torque at the wheels. The test cars were outfitted with the following hardware:

- Dual cone intake
- Upgraded front mounted intercooler
- Downpipes (high flow catted downpipes are acceptable)
- Cat back exhaust system (with secondary cats removed or replaced with high flow cats)

MSRP for the Stage 1 pump fuel software is $800.00.

Stage 2 pump fuel software has an MSRP of $1000.00 (upgrade from stage 1 is +$200.00).

Pricing for switching options is the same for both stage 1 and stage 2. Customers who have options, and upgrade from stage 1 to stage 2, will be able to retain them. However, customers cannot trade in their options in order to upgrade from stage 1 to stage 2.

GIAC handheld switching option (additional to tune):

Handheld switcher: $150.00 (required for switching options)
Stock Mode: +$100.00 (free for customers who purchase a handheld within the 30 days of switching release)
Race Mode: +$200.00
Valet Mode: +$100.00

FYI: You cannot run the GIAC stage 1 and stage 2 concurrently on the same vehicle.
