The core functions are as follows:
- MP48 gas ECU reads the gasoline injection signal of the original car, calculates the natural gas injection amount in real time, and realizes sequential gas injection; gasoline/natural gas automatically switches dual fuel operation with one button, saving fuel costsAEB.
- Built-in fault diagnosis, support computer calibration and debugging; with multiple protection for pressure and temperature, the gas pressure is too low to automatically switch back to the gasoline mode to protect the engine.
- IP54 waterproof ECU shell, suitable for high temperature vibration environment of engine compartment; widely used in taxi, private car 4-cylinder EFI car oil to gas conversion.
Typical failure scenarios (suitable for replacing the ECU) are as follows:
- The gas mode cannot be started, and the gasoline is automatically switched back frequently
- Idle jitter, weak power under gas conditions, tempering
- ECU communication failure, calibration software cannot be connected
- Water ingress, voltage breakdown causes no output from ECU
