Congratulations on your new monitor.

Engine monitors are so valuable that I consider them a "Go--No-go" item for an IMC flight and I would prefer not to fly VMC without them.

The challenge is to learn how to interpret the data that they display. Gaining that understanding will save you a lot of money on maintenance and could, one day, save your life.

(some of the info in the manual concerning the interpretation of the data is factually incorrect--like what happens to the EGT and CHT during pre-ignition. Use the manual to learn how to operate the instrument. It is quite good for that. Be cautious of the materials related to interpreting the data.)
