Data-Driven Diagnostics

Your car’s dashboard is probably home to a speedometer, a tachometer, a fuel gauge, and — if you’re lucky – a coolant temperature gauge. However, your car’s electronic brain (ECU) is actively monitoring dozens of parameters behind the scenes that you, the driver, could find useful. This is where diagnostics hardware and apps like SMARTOBD2 step in, putting all of that data at your fingertips.
