Reviews

Excellent system. Have been using it for 4 years now and it's the only way to go if you are looking at running LOP. Ideal with GAMI Injectors to improve fuel consumption. I regularly get around 28 l/h (7.4 gals/hr)on an IO360.

Q&A

Q: On the JPI EDM 740, what are the dimensions? Can I get a longer harness? Can this unit be installed horizontal or vertical?

The JPI is 3.18W x 4.23H x 2.75D. This fits in a 3-1/8" hole. You can order a longer harness past the 6 foot harness just call or write in the special instructions on how many feet you need. Yes you can mount so that the screen is in a portrait or landscape position.

The JPI EDM 740 4C (10-05188) comes with 4 CHT and 4 EGT probes. For included features please refer to the functions tab for this part. Fuel flow and additional transducers must be ordered separately.

Q: It is possible to connect the JPI EDM 740 or 830 to the new Garmin GTN650 / 750?

Yes, the GTN series can be connected to the EDM series via RS-232 connection.

Q: Can the JPI EDM 740C system be set up to show fuel quantity in more than 2 tanks? (I have 3 tanks)

No, the JPI EDM 740 can only monitor 2 tanks.

Q: For the EDM 740 6C, which functions are included? I expect to have RPM, MAP, Fuel Flow, Fuel press, oil press, oil temp, EGT, CHT

Q: Does this JPI EDM 740 have the ability to data log?

Yes, per the manual this can record data.

Q: Is fuel flow sensor included?? One question you answered and said it must be ordered separately then in another answer you said it was included. Also, is the oil temperature sensor included? It shows it is included in the functions and not in the option functions but you have it listed in the option pricing.

Yes, fuel flow sensor is included. Yes, oil temperature is included as well.

Q: Can this be a drop-in replacement for the EDM-700?

This unit will come with all the probes and wiring. If you want a plug compatible unit, we recommend 10-03864 which is the display only and you keep your current EDM 700 probes. Please be aware that the back of this gauge is 3-1/8" sizing. Also notice this is NON TSO and can only be installed in experimental aircraft.
