## Description

KW206

Review: RPM - Not sure but just run as my company manufacturer forgot a RPM option .
Review: This thing is awesome! I'm impressed with it so far. It works perfectly with a Crown Vic Interceptor. Some of the reviews I've seen where it malfunctions seem like they were made by people who tried to use this device in a car with an incompatible computer system. If you have an OBD II system at least up until 2011 (my car is a 2011), it should work The device is very accurate in terms of the speedometer and tach. The moment I hooked it up, I started getting readings I didn't know my car measured, such as air intake temperature, just to name one If you want the most out of your vehicle, I highly recommend this product. Just a heads up, initial hook will take a few minutes for the device to scan and determine what kind of sytem you have. And, at least for me, to enable sleep mode, I have to keep the key in the ignition until after the countdown finishes. Then the device will reboot with the logo. After that I can take the key out and it will do another countdown until going into sleep mode. Other cars or trucks may cause it to operate differently in this regard. Oh, and not to mention as a bonus, this device and scan for and clear out engine fault codes. The device also has very good build quality, and there's a slight weight to it, still lighter than a samsung galaxy phone, for example. EDIT: I've used the device for over a week now and it still works fine. It's accurate and timely. There's no lag in any of the readouts. For the sleep mode, I discovered you can just shut the car off and take the key out. It may do the countdown and reboot a few times, but it will eventually just go into sleep mode without you having to do anything else. Also, I did order an extra phone holder as the double-sided tape on the devices stand is not strong enough to hold up on a window for too long. This is a minor inconvenience compared to the overall quality of the product
