hubcap Posted May 29, 2022 Report Posted May 29, 2022 (edited) I have a JPI 900 presently, but considering the upgrade to the G3x, should I switch to the Garmin EIS? What advantages or disadvantages to switching? Let’s assume it is cost neutral (I know it’s not) because I am really more interested in performance. Edited May 29, 2022 by hubcap Quote
ArtVandelay Posted May 29, 2022 Report Posted May 29, 2022 No additional functionality, probably 3-5 AMUs in parts and labor.That’s what I am doing, G3X & keeping the 900…if Garmin ever delivers. 1 Quote

What advantages or disadvantages to switching? Let’s assume it is cost neutral (I know it’s not) because I am really more interested in performance. I would recommend - only if you have a standby attitude indicator plus another suitable display to back up the G3X’s engine monitoring functions (such as another G3X dedicated to engine monitoring), then I’d say go for the EIS if you really want, and if the G3X quits, you can fly off the standby + your other engine data display. In general, I love Garmin stuff; however, JPI edges out the EIS in my opinion, simply because I have everything I need in one glance, and it’s completely separated from my primary display. I have hundreds of hours behind the 900 (and the 930 by upgrade) in my previous Ovation, but have the G3X with EIS in my airplane presently. In the course of installing a new engine, I’ve made the decision to remove my EIS, add CIES transmitters, and add another JPI 930 (on order…arriving in about 3 weeks). With the JPI, I don’t have to change pages to lean or perform other functions. I have everything in one view on the JPI, which makes my scan smaller and allows me to focus on flying and monitoring other things. If my primary display quits, the JPI has my back. 3 Quote
PT20J Posted May 30, 2022 Report Posted May 30, 2022 I've flown both. If I already had a JPI 900 I would probably not spend the money to replace it with an EIS. That said, I like the Garmin EIS a lot. I like that the MAP and tachometer are near the primary flight instruments. I like that I can program tick marks on the gauges for normal readings. I like that I can program the alarms slightly above the redlines to avoid nuisance alarms for transitory exceedances. I like the ability to program master caution and master warning alarms to provide voice annunciations via my PMA 450B audio panel. It doesn't bother me that some info is not displayed on the primary display -- it's only a single touch screen tap away and I'm a pilot not a flight engineer so I don't need to constantly see volts and amps and fuel pressure . I also like the way that the EIS integrates with the G3X and GTN 650Xi to provide range data. Skip 1 Quote

If you have an edm 900 and a g3x, and the edm goes out, you’ll be grounded as well. Either way, one screen goes and you’re grounded. However they’ve both been shown to be pretty darn reliable (the screen). 3 Quote

I still think the key is that you already have the JPI900 and it's working well. I would just make sure that when you cut a new panel, flush mount the JPI and install it landscape rather than portrait. If you have the room if you want to spend any money I would check with JPI to see what they would charge you for a 930 display after they take your 900 in trade. The JPI-930 and the EI MVP-50 are the gold standard in engine monitors. I've had two 930s was completely satisfied. 3 Quote
carusoam Posted May 30, 2022 Report Posted May 30, 2022 Engine monitors haven’t evolved much since the JPI900 and EIMVP50… data collection at one point per second is pretty good…. Viewing data through Savvy is the best… The engine monitors also include basic GPS flight data recording and logging… The Garmin EIS does take flight recording to another level…. Lots of various data recorded… Probably not useable data in flight…. And reviewing detailed flight data afterwards, is probably not for everyone…. If you have an all big G panel…. And hardly use your engine monitor beyond the basic leaning capability…. I’m stretching for logic to buy the upgrade for you…. Best regards, -a- Quote

Pinecone Posted May 31, 2022 Report Posted May 31, 2022 OK, starting without either. No engine monitor installed. Garmin or JPI (assuming installing Garman panel? Quote

kortopates Posted May 31, 2022 Report Posted May 31, 2022 Same question. I'm getting a 650Xi for Com1/Nav1 and will use my existing 430 for Com2/Nav2.the GTN 650 Xi is a navigator, not a MFD, and thus it doesn’t support EIS functionality. You would need a G500 Txi, GI-275 mfd or G3x for the EIS functionality.that said it’s largely a personal choice, both have their pro’s and con’s. The JPI has slightly superior functionality in my opinion but Garmin has some very nice integration advantages - yet i still prefer the JPI solution but others may prefer the integration pluses of the Garmin solution.Sent from my iPhone using Tapatalk 4 Quote

It's over $1000 cheaper and offers everything I need. I'm not a pro like most of you here. I just want to be as nice as I can to my engine, and have a better overview of what's going on under the hood. Quote

The EIS uses the G3X Bluetooth to connect to Garmin Pilot, so that would have to be working. Quote
David M20J Posted June 1, 2022 Report Posted June 1, 2022 I am also trying to decide between a JPI 900 or GI-275 EIS. Ive heard a few people talk about the garmin integration bonuses. is there anyone that knows specifically what those are or where I can find information about the integration advantages? I currently have 2 GI-275s, both are primary systems, with a GNX 345 gps, so it would be a third GI-275. 1 Quote
carusoam Posted June 1, 2022 Report Posted June 1, 2022 I tried to post a pic of the GI275 EIS…. For reference… https://www.garmin.com/en-US/p/897577 Soooo… a link will have to do…. it’s kind of small for displaying all the data you would like on a single page…. But it must be using a pretty hi res screen…. To do so…. + the EIS is quite the data logger compared to the older JPI…. One thing I like about the JPI 900 It shows all CHT and EGT data at the same time… https://www.jpinstruments.com/shop/edm-900-2/ One thing I don’T like about the JPI 900 is it overlaps the round hole next to it…. In a quirky fashion… PP thoughts only, not an instrument guru… Best regards, -a- Quote

If you’re planning on putting $$ into an engine monitor, you’re far better-off spending on an EDM900, which does as much - if not a little more - than the EIS, and with about 3x the real estate. Trying to read EIS info on something as small as a GI275 is not something you’ll want to get used to. Save yourself the hassle, find some panel space on the right side, yet close to your radio stack, and get the 900…or spend a little more and get the 930. It’s money well-spent. 1 Quote
rbp Posted June 9, 2022 Report Posted June 9, 2022 Personally, I don't need to see all 6 cylinder temps at all times. 99% of the time i am monitoring the simplified EIS strip on the LHS of the 10" G3X display, and tapping the EIS strip splits the screen and shows all 6 cylinders and everything else in great detail. The greater usefulness of the garmin EIS is that it logs the engine parameters in the same log files as the autopilot and FD commands, air/data computer, navigation, roll/pitch/yaw, servo position and torque, and every other thing in the Garmin system.

oregon87 Posted June 10, 2022 Report Posted June 10, 2022 (edited) The MVP-50P is certainly worth mentioning, as well. It compares very favorably to the JPI and Garmin offerings in both price and functionality. Or, if the 3-1/8" instrument is the preferred form factor, we offer the CGR-30P. Links to both are provided below. Not to mention, we're here on the forum to answer any questions. https://www.iflyei.com/product/mvp-50p-engine-monitor/ https://www.iflyei.com/product/cgr-30p-premium/ Edited June 10, 2022 by oregon87 1 1 Quote
