Security Update, Binary Detection Improvements, UI Updates & EDC16 Sniffer Update
- Improved backend security against potential exploits.
- EDC15 software number (SW) detection had a bug that is fixed now. All projects will be updated as you go, you can either re-upload the unlocked binary file or just open an old project with the EDC15 file in it and the system will fix it automatically to ensure no one gets double-charged.
- Engine displacement and cylinder count are now detected (if available) automatically when creating a new project. This fills in the engine metadata fields in the settings section of your project and helps the website and AI assistant know what hardware you're working with.
- Minor UI improvements around the website and an added sorting feature for the Unlocked ECUs list.
- Driver's Wish, Boost Correction, Smoke Limiter (MAP), N75 Duty Cycle, Boost Limiter, N75 Upper Limit, Inverse Driver's Wish, P Gain, I Gain, D Gain, DT1 Gain and Idle RPM Setpoint (Stationary) criteria expanded.
