AutoDiagnost is a revolutionary tool for test your car’s engine. AutoDiagnost uses the exhaust sound of an idling engine. Algorithm performs real-time processing of your device’s microphone data, detects excess noises, and finally, calculates results as Engine Rating in the range from zero to 100 points.

HOW-TO

– Park your car in a quiet windless place without other vehicle`s noises

– Take a look at RPM Gauge and make sure that RPM is more than 600 and less than 900

– Launch AutoDiagnost. Choose your engine type: 4-cylinder (almost all low- and mid-price cars) or 6-cylinder (trucks, SUVs, etc.)

– After pressing the Start button, hold your device near the exhaust pipe not touching it. When AutoDiagnost detects exhaust sound, you will see the Indicator changes its color from Red to Green. If the Indicator staying Red, pay attention to the prompts on the screen

– When Indicator becomes Green, RPM Gauge with current engine` RPM appears on the screen. Hold your device still, and in few seconds AutoDiagnost stops recording audio and shows your Engine Rating. Make sure that the selected engine type shown on the result screen is right.

RESULTS

Engine Rating is in the range from zero to 100 points:

more than 95 points: The engine runs smooth and sounds great. No excess noises detected

from 70 to 95 points: Engine sounds good. The insignificant amount of noises detected

less than 70 points: Big amount of excess noises detected. Please ensure that your car is parked in a quiet place, RPM is between 600 and 900, and try again. If Engine Rating remains low after few attempts, please visit your car dealer.

DISCLAIMER

The diagnostic method provided by AutoDiagnost cannot give full information about engine status and should only be used together with classic engine diagnostic tests. Use AutoDiagnost only outdoor because of the risk to be poisoned from exhaust gases.

Please note that AutoDiagnost support many devices with different types of microphones and sometimes it is possible AutoDiagnost shows inaccurate results.
