FourStroke can convert your iPhone 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 availble for reading more advanced sensors as well as a performance unlock for a dynanometer (horsepower & torque reader) and a 1/4 mile analyzer (which is only partially limited for free users).
DISCLAIMER: This app requires a third party OBD2 adapter. Please visit our website for details. Like most others this app does NOT support ABS codes. Bluetooth adapters are not supported.
