The UltraGauge OBD2/OBDII is a scan tool/engine data display that works with just about any car made after 1996. As long as your car supports OBD2/OBDII interface. The gauge itself is very easy to install, and can be up and running in less than 15 minutes.

You can get one on their website.

This is not a sponsored review, I just genuinely enjoy the product.
