It connects to the vehicle’s engine ECU via ELM327 (Bluetooth/Wi-Fi) and continuously reads RPM, calculated engine load (Load%), MAP, and fuel trims (STFT/LTFT) during normal driving. Based on this data, it recommends which cells of the user’s own LPG software RPM × Load correction map should be adjusted, in which direction, and by approximately how much.
The Results screen displays a recommendation list for every cell where sufficient data has been collected, including RPM, row, estimated Load%, average MAP, sample count, average fuel trim, and confidence level. The results can be exported as a CSV file.
You can optimize your LPG MAP using the trim values read from the vehicle.
