BV2 is a Plug and play digtial boost gauge which plugs into USB power and requires an OBD2 bluetooth scanner plugged into your car.

Very small at 42×23×9mm.

Measures turbo boost and RPM with automatic peak hold which auto resets after a few seconds. Also measures coolant, oil temperature, and car battery voltage.

If I get enough interest I may sell these in low volume. Some more info at the website below. Note that the website is about the BV1 which is a prototype with a smaller screen which I won't sell.
