Product Overview
The MP48 4-cylinder ECU conversion kit is a multifunctional intelligent gas control unit designed for NGV sequential injection systems, supporting both CNG and LPG fuel conversion for 4-cylinder gasoline vehicles. Built with Freescale 16-bit dual-core microcontroller chips, this auto-parts solution delivers optimized hardware and software layout, strong anti-interference performance and low failure rates for daily vehicle gas conversion projects.
Equipped with real-time driving-condition monitoring, the MP48 ECU will automatically switch back to petrol fuel once system faults are detected. It supports cold start, hot-gas start, and gas-oil blend burning modes. Accurate MAP correction dynamically calibrates gas injection under different engine speeds and loads for stable combustion efficiency.
The upgraded MP48-OBD version reads original-car OBD data, monitors long-term and short-term engine correction values in real-time to adjust gas injection volume, maintains a reasonable air-fuel ratio, and eliminates most factory fault codes triggered by autogas conversion systems.
