takair Posted January 13 Report Posted January 13 I feel like I know that the answer is $$$….but…figured I’d ask. UBG-16 display has started to act funny, mainly when hot. The main symptom is that the bars sequentially show full scale for about 1 second. 1, then the next, then the next….. This will come and go through flight. The corresponding readout does not change by much, but occasionally jumps by a lesser amount. The display also occasionally flickers. Engine runs fine….so seems like it is purely display issue. Anybody see this before with any successful repair, other than upgrade? If upgrade, are there any direct drop ins for the display only? I’m not finding one, but figured I would ask. Also, not finding any serviceable units on line, they seem hard to come by. This UBG-16 was originally installed as a drop in replacement for a US-8A. For the short term, I may simply re-install that, works well, but no bars. (I am in process of buying an analyzer for another project, so trying to spread the pain). The least expensive, new, certified system seems north of $3k. Quote
0TreeLemur Posted January 20 Report Posted January 20 Hi Rob, it looks like not a lot of support here for the UBG-16 display. Nothing comparable on eBay. There are some US-8A's that have been listed for a long time. You might consider making an offer on one of those if you see one that looks like will work. Then again, I suppose your UBG-16 without bar graphs is more/less the same thing. -Fred 1 Quote
Steve Dawson Posted January 21 Report Posted January 21 I have an UBG 16 also that came with my plane when I bought it. It works OK but is finicky. They are at least 15 years old. If you were thinking of something that fits in the same 2.25" hole, an Insight G2 or G3 will fit and they have significantly more information in that small format. http://www.insightavionics.com/bestg2.htm http://www.insightavionics.com/bestg3.htm I'm replacing mine with something that will enable me to replace all the primary gauges. Possibly a JPI 900, Garmin GI 275 EIS or the EI CGR 30P with possibly their combo CGR30C 1 Quote

I ended up finding one locally…and have a line on a second one just in case. Installed it today, in spite of numbing cold, will give it a try tomorrow. 1 Quote

I’ve had to replace toggle switches to make it behave…likely need to do that on this replacement too. My friend has the E3, but has had some problems with it. I hope to do some major updates in a couple years, after I finish another project….so kind of limping by for now. Quote

I messaged him recently about upgrading my UBG to the CGR-30p and they're offering a very attractive credit to do so. 1 Quote
oregon87 Posted January 23 Report Posted January 23 What do the numbers at the bottom (EGT on the left, CHT on the right) of the display indicate when the bars are indicating erratically? It may be probe, connection or wiring related. If you can take a video of the display in flight and send it to me at support@iflyei.com, I will be happy to take a look at it an offer an opinion. Regarding an upgrade path, we are currently offering a $1500 trade-in rebate for those with UBG-16s currently, that wish to upgrade to our CGR-30P. For example, if one were to upgrade to our CGR-30P Basic, utilizing the currently installed EGT/CHT probes and cables, the all in cost for the upgrade would be $1998.00. Unfortunately, the UBG-16's plasma displays have become obsolete. As such, we are no longer able to manufacture new or support old units. Hence the reason for our current rebate offer. 3 Quote

When the bars scroll up, the EGT and CHT numbers at the bottom remain stable. It only seems to happen when the unit is warm. I have never had good luck taking pictures or video of the display….let alone at the moment of failure…..any advice? I found a used UBG-16 and installed it. Corrected the issue, so I think all the thermocouples are good. That is a pretty good offer….will consider it for sure…..don’t know how long I have before the replacement acts up. Any thoughts on how long the offer might be good? Quote
oregon87 Posted January 23 Report Posted January 23 (edited) No date yet as to when the offer will expire. If a replacement display solved the issue, that is fairly definitive proof that the issue is with the suspect display as there are no internal settings that would cause such behavior.

Was looking at the CGR-30P. Seems to have some additional features that I did not realize. Regarding the trade in, I understand that I would use my existing CHT and EGT probes. Would the new unit include RPM and MAP sensors? Fuel flow? Or would it simply do EGT and CHT as I have today? Quote

The CGR-30P Basic always includes RPM, EGT, CHT, fuel flow, OAT, volts and a few timers. As such, manifiold pressure would not be included. However, the UBG-16 can be traded in on a CGR-30P Premium at a discounted price of $2798.00. The Premium version always included RPM, EGT and CHT. At the time of order, up to five additional primary functions can be selected, as well as five non-primary functions. Primary functions are defined as those that are required by the manufacturer and include limits/redlines. A couple exceptions to this rule are a follow: 1. Manifold pressure is always primary on a naturally aspirated engine with a constant speed prop. 2. Each fuel tank occupies one primary screen location. 2 Quote
