Big-G Module In-Cab Monitors
The Big-G In-Cab Monitor was uniquely designed to work with all diesel plug and play modules as
well as most flash tools and hand held programmers. Big-G is the only unit that can communicate
with any manufactures tuning components making it a great addition to any diesel vehicle. The
Big-G Monitor gives the driver the ability to ''switch tunes on the fly''. Big-G can display
up to five different functions at one time or can be reduced down to one function to make the display
larger. Navigation through the system is handled by three face mount gel buttons. Big-G offers the largest
screen on the market today, yet compact enough to fit into any pillar mount based gauge pod.
Furthermore, Big-G is the only In-Cab monitor that will de-fuel based on driver defined EGT presets.
