Very easy to install and use. Great product and the price is right. Always been happy with purchases from Aircraft Spruce.
Great unit. I installed it in my Christen Eagle. Kit is complete with everything you need and other than being time consuming, was a very straight forward install. I just went with the basic CHT/EGT kit, but will add other options later which is simple once the gauge is installed. The display is very nice and bright, and scans automatically through all cylinders. Very easy to understand and use. Finally found a unit that has EGT and CHT in one, color display. Also show system volts.
Only negative comment is the unit didn’t come with all of the connectors or pins . Nice unit
Good for EGT and CHT only. If you want to add other probes it will cost you a fortune. Not worthy at all. I added carburetor probe to it and it displays as a compressor temperature. The temp scale is not the same. The bracket design to hold the unit in place at your panel has a terrible design, the mechanical principles are antagonic. You tie a set of screws the bracket fights to close. You leave two screws from the panel out the bracket flexes to close but now you have only two screws holding your instrument. It is just wrong the way they designed the bracket. I tried to call service for two weeks in a row to no success. Imagine why they are having so many calls! LOL. I also installed the RPM sensor to it and it did not work. The price of the sensor is astronomical for what it is. I have installed the T-30 witch is a wonderful tachometer and the whole unit is cheaper than JPIs tach sensor! and you have to remove your Mag in order to install it in place. It is just not a smart design. The T-30 you connect to your mag wire. Easy, smart, functional practical to install. All in all, I am not buying anything from JPI anymore. Good luck! LOL.

The instrument seems OK. But forget it if you need technical support. Its horrible. Front line person doesnt know anything and back line never return your calls. I should have gone with EI.
Does not properly support ROTAX installation.
I bought a 350 recently. The unit is good. Unfortunately, JPI customer service is a mess. They forgot to include the panel mounting bracket. Then the mailed it to the wrong address. Holding up the whole project.....Oh JPI....work it out already.

Yes, the following probes and functions are included:

No, these are available as additional options. EGT and CHT are the only probes that come standard.
If this is a new install then yes you, will need to order the transducer. If you had a FS 450 and wanted to replace the unit with a EDM 350 you could use the older JPI transducer.
You will need to specify this in the special instructions box when you add this to your cart. You can also specify this in the necessary order form that you send in at time of order.
No, you can only use JPI probes with the EDM 350.
Yes, that is correct.
The difference between the basic and the full packages are the functions that are included.
Basic includes: RPM+EGT/CHT Bar Graph, Fuel Flow, Volts, OAT, Flight & Tach timer and Local & Zulu time.
