With baseline figures and data acquisition completed in stock format, Unitronic interprets the data and recalibrates the Bosch MG1 engine control unit equipped on the B9 S4, S5 and SQ5 to achieve optimal performance through an increase in boost, optimized ignition timing, lambda, camshaft timing, and much more. Research and development of Unitronic’s Performance Software continues with further dyno, track, and road testing, while closely monitoring running conditions through high-speed data logging tools and equipment to ensure maximum performance is achieved, while maintaining complete OEM-like reliability and drivability.

After extensive development time and countless hours of flash protocol testing, a multitude of empirical data is collected from around the world. Once a thorough analysis is completed, Unitronic calibrators develop the Performance Software which is fully optimized for maximum performance while staying within the constraints of the OEM hardware to ensure reliability and drivability are maintained. This results in Stage 1 (91 octane/95 RON) and Stage 1+ (93 octane/98 RON) ECU calibrations fully supported by Unitronic's UniCONNECT+ cable.
