17-10-2022 – SIMOS 19 DEVELOPMENT UPDATE
TVS Engineering is excited to announce that it is currently in the final stage of software development for the latest VAG models equipped with SIMOS19 ECU. While already having DQ381GEN2 software solutions for months, finally SIMOS19 tuning will be released soon as well.
Being at the forefront of VAG tuning for over a decade, and therefore having extensive calibration and reverse-engineering knowledge on the model based Siemens/Continental SIMOS software found in for example EA888.3 equipped vehicles, TVS had a solid foundation to start the SIMOS19 tuning development.
To start the development of any vehicle’s new software enhancement it is critical to understand the calibration environment, hardware, software and their respective limitations. While the 2.0TSI EA888.4 is a successor of the Gen3 engine, it has crucial differences like a new turbocharger and SIMOS19 engine control unit. Achieving more power can be done in hours, but actually delivering stable and reliable performance takes more development time.
Over the last months we gathered, analyzed and verified tons of data from comprehensive data logging equipment and external sensors on our own Golf 8R development vehicle, dealer promo vehicles and vehicles which already had the TVS DQ381GEN2 software enhancements.
Meanwhile the new 2.0TSI EA888.4 engine components were studied, SIMOS19 factory software was reversed engineered to actually understand its inner routines and base tunes were prepared. As soon as the SIMOS19 was unlocked our R&D department started real world validation.
Instantly satisfying results were achieved which closely matched our simulations and expectations. However, we at TVS made a well-considered decision to not rush the software release but continue gathering data instead. After verification of the beta software our R&D team made further modifications and improvements. Additional safety features were added over factory routines and endurance tests were developed to ensure maximum long-term performance.
