Attention! ECU Reflashing Required! Up to 32 firmware modes โ for complete freedom to customize performance. Use several modes at once โ combine them for maximum flexibility. Modes are saved in the ECU โ your settings stay even if the ignition is off and reload automatically. Secure access โ each ECU has its own code, which can be entered quickly via QR scan. Multiple cars? No problem. The app automatically picks the right code for the connected vehicle. Brute force protection โ keeps your security code safe from hacking attempts. Advanced access levels โ unlock extra features with a separate code, without reflashing the ECU. Anti-theft mode โ blocks unauthorized reprogramming via the OBD port. Safety first โ some modes (like ANTI-THEFT or E85) can only be enabled when the car is stopped (0 km/h, 0 RPM). Dual ECU support โ keeps both ECUs perfectly in sync. Trouble code handling โ read and clear error codes in seconds. Fast connection โ instantly reconnects to your paired ELM327 device.

The clearest difference is update cadence: Diesel+ at weekly against TuningHost's fortnightly. TuningHost's advantage is iOS requirement (17.6 vs 26.0). On price, ads, in-app purchases and device support there is nothing between them.
