Unitronic® Stage 2 Performance ECU Software is now available for the MK8 GTI®, MK8 Golf R® and 8Y S3® equipped with the 2.0TSI EVO4 engine. With testing and validations completed, power outputs on the MK8 Golf R and 8Y S3 are increased by up to +133HP / +121LB-FT with Unitronic Stage 2 93octane/98ron Performance Software for a maximum of 470HP / 431LB-FT*. Power outputs on the MK8 GTI are increased by up to +119HP / +115LB-FT with Unitronic Stage 2 93octane/98ron Performance Software for a maximum of 385HP / 399LB-FT*. These software upgrades are fully 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. Support for E85 is coming soon!
Expanding on its extensive experience with the SIMOS controllers found in modern VW and Audi vehicles and being the first major North American tuner with Performance Software offerings for the SIMOS 19.6 equipped MK8 GTI, Golf R and 8Y S3 (including at-home tuning via UniCONNECT+), Unitronic Engineers wasted no time recalibrating the new SIMOS 19.6 ECU to achieve more power and torque with Stage 2 calibration optimizations including recalibrated boost regulation, optimized ignition timing, lambda, camshaft timing, and much more after upgrading to a performance downpipe.
Unitronic Software and Hardware Engineers are continually collaborating throughout the research and development phases. On the hardware side, Engineers developed the upcoming Unitronic Performance Downpipe to dissipate exhaust gasses and reduce backpressure on the turbine more effectively and collaborated with the Engineering team on the software/calibration side to work through 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. Extra attention was paid to turbocharger shaft speed, exhaust manifold absolute pressure, intake pressure and much more to ensure this high level of reliability was achieved.
Aided by empirical data collection and instrumentation, it’s common for Unitronic Engineers to uncover factory hard part limitations where such inhibits maximum performance either through efficiency short-comings or air-flow restrictions. In the case of the 2.0TSI MQB EVO4 engines, Unitronic found the factory intercooler quickly heat soaks and loses its ability to keep charge air temperature at reasonable levels before the ECU’s logic intervenes to reduce output based on IATs being too high. Thus, a Unitronic Intercooler Upgrade was required in order to achieve maximum output and published power figures. Going one step further for Stage 2, a downpipe upgrade will be required in order to alleviate downstream restrictions and optimize turbocharger performance to unlock even more power.
Continuing along and similar to the requirements for Unitronic’s Stage 1+ unlimited torque calibrations, Unitronic Engineers also quickly identified gearbox originating torque limitations on the TCU side of the DQ381.2 gearbox. In order to overcome these limitations while ensuring proper torque management and thus, clutch operation with maximum torque calibrations, TCU Performance Software is required for Stage 2 ECU calibrations. Unitronic Stage 1 TCU Performance Software increase clutch pressure to support up to 600NM and is suitable for all Stage 1-2 ECU calibrations. It was developed to improve your overall driving experience through calibration adjustments including an increased torque limiter, advanced torque management, adjustable launch control, optimized gear shift points, quicker shifts, and gear display enabled. At the moment, only DQ381.2 gearboxes with BLvXXXX0301 are currently tunable through the OBD2 port with support for the newer TCUs with BLvXXXX0401 in the works.
If you have a vehicle with the latter TCU, Unitronic offers both Stage 1 and Stage 1+ ECU Performance Software suitable for use with the stock TCU calibration in a limited torque format with Stage 1+ for 93oct on a MK8 Golf R or 8Y S3 making 430HP/377LB-FT. Once support is unlocked for the latter TCU types, you’ll be able to purchase our TCU Performance Software and use our Stage 1-2 Calibrations engineered for use with our TCU Calibrations to unleash your vehicle’s full potential. An upgraded clutch is strongly recommended for MQ350 equipped MK8 Golf R and MK8 GTI vehicles using our Stage 2 ECU Performance Software.
Unitronic Stage 1, Stage 1+, and Stage 2 ECU calibrations are fully supported by Unitronic’s UniCONNECT+ cable, which enables you to not only tune your ECU and TCU from the comfort of your own home or garage, but also gives you access to data logging** and analysis** and much more. These additional resources can and have been proven very effective to aid customers in not only learning more about their vehicle’s performance, but also achieving the absolute best results possible.
It’s important to note that it doesn’t stop here for our development team as we’re committed to continuing onward with our expansive development of these new platforms while we also anxiously await getting our development cars back to the track in the near future to continue on our never-ending pursuit to further improve on our results and welcome feedback, data, and information from our customers all over the globe. Support for E85 is coming soon!
