With extensive experience and a solid foundation of Performance Hardware and Software offerings for the B9 platform, Unitronic Engineers recalibrated the BOSCH MG1 ECU in the RS 4 & RS 5 with total boost regulation control, optimized ignition timing, lambda, camshaft timing and much more. Research and development continued with further dyno 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.
With testing and validations completed, power outputs are increased by up to +118HP / +149LB-FT with Unitronic Stage 1+ E85 Performance Software for a maximum of +571HP / +574LB-FT when combined with Unitronic Stage 1 AL552 TCU Performance Software for seamless operation.** These software upgrades are entirely compatible with our UniCONNECT+ cable, empowering Clients to tune their vehicles directly through the OBD-2 port within minutes, from the comfort of their own home or garage.
