RST SOFTWARE V1.0.43 User Manual Web: RacingSimTools.com Discord: RST Discord Channel Twitter: twitter.com/sim_tools Email: [email protected] User Manual RST Software V1.0.43 ©Racing Sim Tools PREFACE 2 Preface Welcome and thank you for purchasing our new RST Software. This new software is a complete revamp of the PC2Tuner app with highly expanded functionality that’ll provide you far more tools to optimize your car setups effectively. With expanded functionality comes increased complexity. So, don’t be surprised if you feel a bit lost at first, even if you’re already familiar with the PC2Tuner app. Please take your time and study this manual carefully. It’ll guide you through the process of installation and initial telemetry recording, provides some tuning essentials and gives a detailed overview of all the tools available to help you become familiar with the new app. We hope you’ll enjoy using this tool as much as we did, building it!
