Chiptuners Automotive The Chip Tuning Experts is pleased to present the ultimate engine control unit (ECU) upgrade for the high output 2.0T Mk7 Golf R and New Audi S3 Engines! ECU upgrade is available in octane-specific variations and is conveniently flashed to the vehicle’s factory ECU through the OBD-II port without any physical modification to the factory ECU.

The ECU’s Siemens Simos 12 engine management system is responsible for proper operation of the engine during constantly changing environmental and load conditions. With built in compensational data for environmental variables and varying load conditions, the factory ECU is far more complex and intelligent than units found in other vehicle makes and marques.

We have spent months calibrating the engine management system, including many hours of chassis dyno development. With a thorough understanding of the ECU’s torque structure, Our Calibration Engineers properly increased engine load to produce more power and torque across the entire power band. ECU Upgrade increases boost pressure, optimizes ignition timing, cam timing, lambda and more to produce higher output!

New 2015 RS3 is covered via OBD expect 60+bhp with 80nm!!!
