Hi,

Cessna 180 with an O-470R.

Which Eng. Analyzer should I buy and why?

Eng info like MP, RPM, FF, OAT, HP would be nice to have but not a must.

Budget, bout 4K USD


Thanks,

Manuel

I have an EI CGR30. It works fine, and does everything you listed. Advantage is that it fits into a 3 1/2" hole, so panel work is minimal.

Personally, I'd take a hard look at the Dynon Skyview. You can buy a 7" display with engine monitoring for about $4700. Add the AHRS for another $1200, and you would have a glass panel that would eliminate almost everything in a VFR steam gauge panel.

I don't have all the bells and whistles with the JPI 730, but I sure like the unit. The screen is easy to read, I have no regrets on installing it. I had an old EI, other than that I have no experience with anything else.

I have now used EI CGR-30P, UBG-16 and JPI EDM 700, 830, 900, and 930.

The EDM930 is the best with the 900 a close second, simply a tad bit smaller but same functionality and fits in 3 1/8" hole. Both are full replacements, no other engine instruments will be in your panel. EDM900 in my opinion is by far the best bang for the buck, just look at the specs. MVP is $$$$, and CGR isn't a full replacement while still costing the same as an EDM900.

The UBG-16 and EDM700 are both excellent for the cost if you only want to add the CHT/EGT. It seems like the EDM700 is more expandable than UBG-16. The 700 I use regularly has Volts, Fuel Flow, TIT, Cooling rate in addition to CHT/EGT. I also loved my UBG-16 in my 180 though, they are essentially the same.

I would never buy a EDM730 or 830 because you're spending money to show repeats of what's already in your panel (RPM, MP, etc). I don't see a need for anything between the UBG-16/EDM700 and the EDM900.


All that to say... EDM900 and be done with engine instruments forever. It will truly change the way you operate your airplane. $4437 from Spruce. Or go with a UBG-6 or EDM700. These can be found used online frequently for $1000.

FWIW, the CGR 30P will replace everything except fuel gauges. So if you can live with stock fuel gauges the great. If you want to go with different fuel gauges then you really need new senders as well, so cost goes up. But even without fuel the EI is a bit cheaper.
I like both the EI or the JPI, I dont think you can go wrong with either. I'm putting a CGR30P in my 206, and an MVP50 in a 182 here soon. I have customers with JPI units that are liked as well.
In reality though these are all $4000+ to buy, and probably another $3-4000 to install. So unless you are doing the install yourself you need to add that to your budget.

Nope...it’ll do fuel gauges as well... Ei made my fuel sending units for Dakota Cub tanks...

Just consider what install will cost, no matter what unit selected. Especially if you don’t have the leads run already.

It will, but if he wants to replace all his other gauges as primary, he won't have enough to do both tanks as primary as well. So he still can't use them as replacements.

Either the EDM 900 (my favorite) or the CGR 30 are going to eat his budget just to buy the unit. Then you’ll have installation, which may run as much or more than the unit itself.

Second point: CGR 30 fits in a 3 inch hole, but requires a separate control unit, which has to be mounted somewhere else. EDM 900 contains everything in the panel mounted unit. So install can be a little different.

But for the money he noted, he’s not getting either of those units.

It's my understanding that the info has to be displayed on the "front page" to be considered a primary gauge replacement?
Primary gauges in an early C180 with the old wingroot fuel gauges would be MP, RPM, CHT, EGT, oil pressure, oil temp, amps (or volts?).
Fuel flow, OAT, carb temp, etc are not primary gauges & so could be displayed on a secondary page.
You could also have fuel quantity on a secondary page, if you could install senders in addition to the stock mechanical gauges.

To the OP, if what you really want is an engine analyzer and not to replace all of the other instruments, you can get the job done within your budget with an Insight G2, $2275 plus installation, which is pretty straight-forward. Or you can get more bells and whistles with the G3, $3367, but it might be hard to get it installed within your remaining budget.

I have a G1 in my P172D, Lycoming O-360, which is pretty basic--I get CHT, EGT, and carb temp, and no storage. But it works for me. The G1 is not available for a 6 cylinder engine. I have been very happy with the G1 and with the tech support from Insight, which I think is important. However, if I were to do it again, I think I'd go with the G2.

I initially had the first G1 in the US, installed after TC had approved it but before the FAA STC was approved, which my IA installed using a 337. The STC came along several weeks later. That original one glitched and had to be replaced. Insight sent me a new one and trusted me to return the old one, so that I had almost no downtime. Good folks.

Thanks a lot for the informative replies!

Should have stated that all space left in my panel is for a round 3 inch instrument or to say the 730 /830 rectangular size face.

Yes, I will have to increase the budget. That is OK. Good point.
Pretty sure instalation here in Guatemala will be cheaper than in the states.

Mainly interested in having independent CHT and EGT for each Cyl. trend monitoring and warnings. Backup MP RPM OAT OP OT will be nice to have.

Any comments on the 830 unit? Believe it is like a 730 with the ítems I listed as backup ones allready included. (+ HP)

I installed a 830 last year, I think it's great, lots of good data. No better than E.I., I don't imagine, but like all the information, leaning, gph, cylinder differential, everything in the green at a glance, all that.

Tks Hman

What might be better on the E.I?

I meant that I haven't owned a E.I. monitor, but the comparable unit likely works as well as my JPI. I didn't want to imply that my JPI was "best", just because that's what I chose to install.

I really like the color CHT/EGT display on the EI CGR30.
I would kinda like a simple CHT/EGT gauge with a similar display.
Like this one:

I want CHT & EGT-- I don't really need or want OAT, carb temp, fuel flow, rpm, mp, oil pres, oil temp, amps, volts, TIT, etc etc.
I've already got all the required primary info on the stock gauges.
Unfortunately for me, most manufacturers want to make the devices the be-all, end-all ultimate instrument.
It doesn't cost them much more to add all sorts of capabilities, they're only limited by the size of the display.
However, that does run the price up for the buyer

Ditto for flight instruments-- hardly anyone makes a simple electronic horizon.
My Garmin G5 also has a GPS-driven directional info, which I like.
However, I don't really want or need the pitot-static driven airspeed / altimeter / VSI f=feature it also has-
luckily for me, it's possible to disable those.
But the newer stuff has all that, plus synthetic vision, GPS nav, etc--
just too much going on for my tastes.
I subscribe to the "keep it simple" school of thought.

Speaking of which, what is the legality of installing a non-TSO'd instrument such as this,
provided that it is not used to display primary information?
I could keep the stock required single-point CHT gauge in the panel, using a spark-plug-gasket type sensor,
and have this multiple cylinder display (using bayonette type sensors) in addition to it.

.

I think every digital monitor besides EDM700 and UBG16 have a color EGT/CHT. They pretty much all turn red when high, etc.

I see what you mean, a nice simple monitor like the UBG but with an LCD display like the larger units.

My understanding is that so long as the required instruments from the TC are installed in accordance with the regs, any additional instrumentation the owner wants to add is fine.

Very good size graphics on that unit Hotrod180. I like it much. Tks!
Anyone using it?

I like the JPI feature of recording parameters. It may be worth to see trends and also to go back and see.
