GIAC Software Upgrades – BMW ECU Tuning
For over 20 years GIAC has been engineering software for BMW engines. GIAC is known for creating performance ECU software that leaves the high quality, smooth feel of your BMW while generating significantly increased power, torque and improved throttle response.
Known as an ECU flash, the software replaces the factory ECU performance data and is optimized to adjust ignition timing, fuel delivery, boost settings, rev limiters, and speed limiters to optimize engine performance. In most cases we can re-flash your BMW ECU in a few hours and deliver you back a car with more power, torque and solid reliability.
GIAC also offers competition software enhancements like launch control, left foot braking, race fuel maps, modified limiters and calibrations for popular racing hardware.

GIAC ECU Software Upgrades for BMW – Our Opinion
Rennology Motor Sport has been the preferred GIAC dealer for the Chicago area for more than a decade. GIAC’s ecu tunes produce excellent power and extremely smooth power delivery. We have never encountered check engine lights or other issues on cars we have flashed with their software. Highly recommended.
