## What is 997 Chrono?

Control and update your 997 Chrono display from the comfort of your iPhone. Designed to Fit Porsche 911 (997), Boxster and Cayman (987) vehicles.

The 997 Chrono is designed to replace the Sports Chrono stop watch in the Porsche 911 (997 model, 2005 to 2012) and the Boxster and Cayman (987 model, 2005 to 2012).

Once fitted, the display can show you:
* Water temperature

* Oil pressure
* Battery voltage
* Boost pressure (turbo models)
