The Viking View is used as a simple EIS to show all the engine parameters in a plug and play system.

For pure simplicity and maximum bang-for-your buck, go for the pre-wired electrical panel and the Wingbug.  You will now have full engine monitoring and all of your flight instruments installed at a huge saving to any other combination on the market.  Plus, this panel is easy to upgrade if you ever like, saves on a lot panel space and can be retained as either your primary or a back up system into the future.  All you need is your communications suite and you’re done.
