Review on ATOTO AC 4450 Bluetooth Diagnostic Scanner by Eric Cooper

I bought it for my ATOTO A6 radio. I always leave it on. Excellent value for money and quality. It reads engine codes and even looks them up online for you. When you download the TORQUE app, it takes about 30 seconds before it starts reading data from the car's computer, but then it transmits all the data in real time. It also displays all engine stats in real-time. For example miles per hour, fuel level, miles per gallon, RPM, you can customize what is shown and how. The adapter even works with your phone via Bluetooth, so you can use it in other vehicles if needed. It reads hundreds of stats - you'll never use all the features it has, but it's great that it has them all. There are even gauges that save your max and min readings and you can set alarms. In case you are monitoring engine temperature or just calculating your best score from 0 to 60.
