While reading fault codes and checking sensor parameters is entirely safe, changing the gas injection maps or adjusting pressure thresholds should be approached with caution. Incorrectly leaning out the fuel mixture at high RPMs can significantly increase exhaust gas temperatures (EGT), potentially causing severe engine damage, burnt valves, or catalytic converter failure. If you are unsure about the map values, use the software's "Auto-Calibration" feature as a baseline, or consult a professional LPG technician.

The software is designed natively for Windows (Windows 7, 10, and 11). Ensure your laptop battery is fully charged before connecting to the vehicle. Step-by-Step Installation and Connection Guide brc sequent 56 software download

To connect a modern laptop to an older ECU, the correct USB drivers must be installed. Many modern USB-to-serial converter chips (like FTDI or Prolific) are automatically detected by Windows 10 and 11. However, some older interface cables may require specific, legacy drivers to function, especially when used with 64-bit versions of Windows. Without the correct drivers, the software will be unable to establish communication with the ECU. The software is designed natively for Windows (Windows

The system works by intercepting the signal from the vehicle's original petrol ECU. The petrol ECU calculates the optimal fuel quantity and injector opening time based on driving conditions and performance demands. The Sequent system takes this signal, processes it, and then controls the LPG injectors to inject gas in precise synchronization with the engine. Because the system integrates seamlessly, the original vehicle diagnostics remain fully functional, and the gas ECU continuously adapts to engine wear, helping to maintain lower emissions and stable performance over time.
