PMA-2 is an automatic data collection system for petrol electronic fuel injection monitoring. It uses a standard fuel injection setup such as those found in petrol-engined vehicles, and gathers data from fuel injectors and other components as they operate. The PMA-2 allows real-time data logging; all collected data is stored in the onboard EEPROM for later analysis. This data is analyzed by the onboard processor to allow the user to identify problems such as improper air/fuel ratios, misfiring, lower or higher than normal fuel consumption, and engine mismanagement.

PMA-2 Application Field

PMA-2 is suitable for monitoring the performance of petrol powered vehicles as it records parameters like air/fuel ratio and engine RPM. Such information is especially useful to vehicles used for off-road racing, or where accuracy and precision are important during long-distance races or trips. By collecting data on fuel injection system performance, the PMA-2 can identify any performance issues and provide adjustments that can improve performance. Additionally, PMA-2 data logging can be used to measure real-time fuel consumption, allowing the driver to adjust their driving style in order to save gasoline and extend the vehicle’s range.

Working Principle

PMA-2 works by capturing digital signals from the fuel injection system. It uses a digital to analog converter (DAC) to convert the signal from digital to analog before sending it on to the PMA-2 processor. The DAC is used to measure fuel bores, fuel pressure, and fuel injection timing. The PMA-2 then analyzes these signals and transmits the information to the host computer. This allows the user to receive real-time diagnostic information about fuel injection system performance while the vehicle is in action.

In addition to monitoring performance, PMA-2 can also be used to tweak the fuelling system by reprogramming the fuel injectors or other components. This can improve or reduce horsepower, depending on the user’s desired outcome. PMA-2 also allows the user to check fuel injector status to identify faults, and can monitor the amount of fuel used by the vehicle. These functions can help the user to identify potential fuel wastage and reduce it instead.

Conclusion

PMA-2 is an essential tool for anyone looking to get the most out of their petrol-engined vehicle. It provides real-time data logging, allowing drivers to monitor and adjust engine performance when needed. This can help to improve fuel efficiency, acceleration performance, and general engine management. By analyzing input signals from the fuel injection system, the PMA-2 can identify problems and help drivers to make the necessary adjustments as quickly and easily as possible. This makes the PMA-2 an invaluable tool for any serious petrol-engined vehicle owners.
