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.
