Rotax 912 Change to Coolant Temp Sensors

[James_Rekieta]

I am presently installing a D180 with a Rotax 912 engine.
It seems that Rotax has changed their engine temperature sensing from 2 CHT probes to Coolant temp sensing using two probes located on top of the heads of #2 & #3 rather than the two probes located on the lower area Of #2 & #3 cylinder heads. I figured this out after installing the wiring as described in the D180 manual as connecting to CHT probes :-[. This shouldn't be a big problem changing the wiring but I'm wondering where do I connect the wiring for the coolant probes on the D180 end of the harness? The manual only describes the installation of one coolant temp probe. Also, Rotax describes the coolant probes as being the same probes that were used for the CHT setup just at a different location.
Any help would be greatly appreciated.

We suggest that you connect the two Rotax 912 iS temp sensors as "ROTAX CHT SENSORS" as described on Page 3-15 of the FlightDEK-D180 Installation Guide.

Thanks, Will do.
I gather that I'll be able to configure these as coolant temperatures when I get to the configuration section. BTW the engine is a 912ULS; not that it makes any difference. This obviously is a rather recent change in the installation of the new style heads affecting the 912/914 engines. The "Temporary Revision" has a date of March 3, 2015 printed on it. Seems that the new location of the sensors, reading coolant temp rather than metal temp, gives a better indication of overall engine temperature and that the new location of the sensors allows for easy recognition of coolant loss.
FWIW,

Unfortunately, no, configured as described, these sensors will be displayed as CHT L and CHT R, but given that they're the same physical sensor, this should work. The label - CHT L and CHT R is a fixed functionality in the older Dynon Avionics EMS units such as the FlightDEK-D180.

Ok, Whats in a name anyway As long as I know what they represent and most importantly that they remain within specified limits. Didn't realize I was buying "old" technology. Figgered I was stepping up in the world purchasing this fine glass instrument Guess I'm always a step or two behind :-?
Very good forum! Thanks again,

SkyView is our newest product line, incorporating all the things we learned building our previous products. For example, all the engine sensor labels are user-settable, so in this issue, in SkyView, you would just change the label for these sensors, for example, from CHT L to COOL L (labels are 6 characters).
