Description

FourStroke is a powerful tool that analyzes and displays real-time vehicle sensors and data through your vehicle's OBD2 port, a port standard on most vehicles across the world. Use of this app requires a third-party OBD2 Wifi or Bluetooth BLE Adapter. Our app is FREE to pull and clear engine codes along with most other functionality!

FourStroke can convert your device into a heads-up display of just about every sensor your car supports, without needing expensive gauges. Sensors include RPM, coolant temperature, vehicle speed, air flow, O2 sensor data, and more (sensor support varies based on vehicle).

Quickly diagnose a check engine light (CEL) by pulling up exactly what error codes are present. FourStroke automatically turns the code into a readable description. Your vehicle also may store 'Freeze Frames' that detail what sensor data was present when the CEL first occurred; FourStroke can display this information for you.

In-app purchases are available for reading more advanced sensors as well as a performance upgrade for fully unlocking our dynamometer (horsepower & torque reader) and a 1/4 mile analyzer.

DISCLAIMER: This app requires a third-party OBD2 adapter. This app does not support ABS codes or proprietary commands.

Won't See V-Linker FS Bluetooth

Mikeybc31 on

Thought it would be able to recognize a V-Linker FS Bluetooth, Wrong, I have no issues with OBD Fusion and Car Scanner pro so I'm not sure what is going on.
