A pressure measuring device/system that is capable of measuring the pressures of multiple systems in an automobile, including cylinder pressure, fuel pressure, transmission oil pressure, and engine oil pressure, and is capable of displaying and/or recording the measured pressure values remote from the device taking the measured remote pressures. The pressure measuring system has a remote interface and a sensor configured to communicate wirelessly with each other. The interface may be configured to he included within the device purpose built for displaying and interacting with the pressure values measured by the sensor. Additionally or alternatively, the interface may he configured to he downloaded as a mobile application “app” on a smartphone or other similar device.
