anyone using the JPI FS450M

Hi Brian
Do you already have an engine analyzer?

[bjherron]

While getting ready to order the FS450M, I changed my plans. I ended up buying the JPI 751, an engine analyzer with two 4" screens. It's approved as primary for CHT and oil temp. I added the fuel flow option, and it also comes with TIT, OAT, Volts, and 12 EGT/12CHT probes. I will eventually add RPM/MAP, oil pressure, and fuel pressure to give me a full view of both engines.

Unforutnatly it's not approves as primary for all instruments, so I'll have to keep some of the stock gauges. When I do a whole new panel my plan is to replace the primary gauges with different ones that have remote sensors so I can get the wet lines out of the cockpit.

For the price it was about 1/3 the price of a complete primary certified display. It was almost the same price as the "skymaster" version of the Insight G4. They aren't shipping the G4 yet but they'll pre-sell it to you and give you two G3 head units now. I ended up going with the JPI because the screens were larger.

Here's a pic of it in a different plane, this is how I plan to mount it.

The most important aspect of adding FF is that it's data be in the engine monitor download. Having each engine's FF individually catalogued is very helpful when troubleshooting engine problems.

Take a look at the Flight Line (Xerion) 2120 for a twin. It replaces all factory gauges.

one more update here. After hassling with JPI and aircraft spruce I ended up cancelling that order. I instead went with the Insight G4. They have a package for Skymasters that includes the whole engine monitoring system. They also have an STC for primary on cylinder head temp, exhaust gas temp, and TIT. They have also applied for a future STC for primary on oil temp, oil pressure, and MAP.

The G4 system is not shipping yet, so they are loaning me two G3 gauges until a single G4 comes in.

I also contacted Shadin and they can sell me a used gauge that will connect to the G4 fuel flow sensors and give me the STC for primary fuel flow on the shadin unit.

In the end it was a much better deal than JPI with more features.

Let us know how they work...I'm thinking about putting the same thing in the panel...also if you don't mind...what's the cost?

[bjherron]

I Sent you a PM with he cost details

update: Monitor installation is mostly complete. We used the access panel in the back to route the wires thru. All of the sensors are wired in, all we have left is to wire in the gauge.

Along the way, I found out that you can actually wire the Shadin Digiflow to the engine monitor. Shadin says you can either use their fuel flow sensors or the Insight G3 sensors to drive both gauges. The big advantage to this is that I will be able to get rid of the wet fuel lines in the cockpit.
