FourStroke OBD2 Elm Scanner: Real-Time Vehicle Sensor Analysis

FourStroke is a powerful tool that allows you to analyze and display real-time vehicle sensors and data through your vehicle's OBD2 port. It is compatible with most vehicles worldwide and requires a third-party OBD2 Wifi or Bluetooth BLE Adapter. The best part is that the app is free to use for pulling and clearing engine codes, along with other basic functionality.

With FourStroke, you can transform your device into a heads-up display for a wide range of vehicle sensors, eliminating the need for expensive gauges. It provides information on RPM, coolant temperature, vehicle speed, air flow, O2 sensor data, and more (sensor support varies based on the vehicle).

One of the key features of FourStroke is its ability to quickly diagnose a check engine light (CEL) by retrieving error codes and providing readable descriptions. Additionally, if your vehicle has stored 'Freeze Frames' that capture sensor data when the CEL first occurred, FourStroke can display this information for you.

For advanced users, there are in-app purchases available to access more advanced sensors. You can also unlock additional features like a dynamometer for measuring horsepower and torque, as well as a 1/4 mile analyzer.

Please note that FourStroke requires a third-party OBD2 adapter and does not support ABS codes or proprietary commands.
