CIRI - Car Intelligent Recorder and Interpreter is a tool that listens to a working engine. Engine's mechanical complexity gives a symphony of sound. CIRI identifies those oddball sounds and helps you sort out which conditions you can let slide and which ones mean repairs—and how fast you need to make them. By modern analysis and CIRI Cloud Server processing and comparing to known sounds and malfunctions of engine it looks for problems before they occur. It can be also used as RPM meter (tachometer) with shift-light function.

Usage:

1. After starting CIRI RPM Tachometer, please select your car parameters (or similar car), check if cylinder count is correct for your car.
