Motroxia turns your Android device into a customizable in-car meter that shows your car's engine data in real time, using an ELM327-compatible OBD2 Bluetooth adapter.

■ Main Features

◆ Real-time display
Just connect to an ELM327 adapter over Bluetooth to see engine RPM, vehicle speed, coolant temperature, boost pressure, throttle position and more in real time.

◆ Free customization
Arrange widgets freely with drag & drop. Choose from a variety of display styles such as analog gauges and digital readouts. Create multiple pages and switch between them to build layouts for different driving scenes.

◆ Wide OBD2 PID support
In addition to standard Mode 01 PIDs (RPM, speed, coolant temp, MAP, MAF, etc.), Mode 22 extended PIDs are supported. Derived values such as boost pressure are calculated automatically.

◆ Custom PIDs and formulas
Define your own formulas to create original readouts — for example fuel economy, estimated horsepower, or manufacturer-specific PIDs. You can compute from raw bytes using syntax like [010C:A], and reference aliases too.

◆ Demo mode
Even without a car connection, you can try the app using demo data that reproduces a realistic drive cycle.
