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.

Keine Öl Temperatur
Leider wird keine Öltemperatur trotz Kauf und Auswahl angezeigt. Eine andere App kann es. Leider nur auf Zeit. Aber ohne weiteren Kauf. Das KFZ hat einen Öltemeratur Sensor. Beim Fahren wird plötzlich die Boardspannung mit nur noch ca.2 Volt angezeigt. Und auch die Wassertemperatur schwankt extrem von 0-140 Grad umher.Schade.
Cool!
Can you please add a dash with 3 gauges and the possibility to add a clock, because in landscape mode the clock is not visible in the status bar.
Russian...
Language set to russian with last update, so I cant use it anymore, dont know how to switch back to english. Main problem with this is that I bought premium earlier
