Can I yank my original CHT gauge in the 182B if I install a EI UBG-16 with all six CHT monitored. Be nice to open that space for somthing more usefull. Maybe Matt at EI can chime in on this. Had a good phone conversation with him this afternoon and forgot to ask him about it.

If it is part of your original equipment list then no you can't remove it. You can piggy back or put the probe in a different location but you can't remove an original CHT gauge.

Thought that some of their stuff was counted as a replacement but maybe not this. I can just move the original guage to some out of the way place (like the back seat).

I liked the comparison between the UBG-16 and the original equipment. There is quite a delta between the two.The good news is that the CHT & EGT do not get as hot as the original gauges indicate. I also added Oil temp, here again lower than original gauge and OAT which gives me the warm and fuzzies on cold days.
How is the hobby shop going?

Yes, you can. I did just that with my 182, although I used the US8-A, the non bar graph model. I believe the UBG-16 is STC'd as a primary replacement, if so you remove your factory CHT and EGT. Would be hard to believe the newer model wouldn't be STC'd as a primary replacement.

You better talk to EI because they were the ones that told me no if it is on your original equipment list! They gave me a piggy back probe because the CHt could not be removed.

Plane is in the hobby shop. Finished the doors this morning. I am soooo excited. Nipples haven't been this hard since the Craftsman sale at Sears last year.

Will talk to EI. One of those guys reeds this forum. Maybe he can shed some light?

You just might end up preferring your original CHT gauge, especially if it is analog.
The reason is RESOLUTION.
I have one of the engine analyzers where it is rather easy to determine the EGT, but the CHT leaves a lot to be desired. The CHT bars on mine are embedded down on the bottom within the EGT bars. The best I can do with them is to tell if one of the Cylinders were to go WAY our of wack. While the analog gauge that came with the 180hp conversion to my 170 is only on one cylinder. It is my ASSUMPTION, I know, that it was placed on the inherently hottest cylinder. I still keep an eye on that one for CHT changes since I can actually see if and when the needle is moving or moved.
So far, so good.
This is only presented as my subjective position.
It may be that I have never learned how to use the damned CHT section.
