Combined CHT/EGT graph supported for Rotax 912ULS?

[mwtucker]

I have been trying to get a combined CHT/EGT graph displayed across the bottom of the display. I can't figure out how to do this. Does anyone have a Rotax 912ULS with the combined display? I am beginning to think this is not a supported widget for the Rotax. I have 4 EGT probes on the cylinders, but only the two "CHT" (coolant) sensors that Rotax supplies on the engine. I can display separate EGT and CHT readings in the many different formats, but the option to select the EGT and CHT combined widget does not appear in the "sensor" drop down box on the screen editor. Has anybody with a Rotax done it?

Thanks!

I have it on mine, but I don't remember how I did it and I'll try to look into in a day or so.

Thanks. I wonder if it is because I have 4 EGT probes and only 2 CHT sensors (the 2 that Rotax supplies)? Perhaps the number of EGTs must equal the number of CHTs for the Combined graph widget to work? Do you have 2 EGTs and 2 CHTs (coolant)?

No, I have 4 EGT and 2 CHT in one of my airplanes. I'll try to remember to take a picture of it today and maybe see how I set it up.

OK...thanks for that.

I couldn't get it today. Here is the location of the editor: Installation Manual SETUP > EMS SETUP > SCREEN LAYOUT EDITOR. I'll try again in the next few days.
HDX Users Manual: Combined CHT/EGT Widgets talks about it.

Here is a display of the combined 4 EGT 2 CHT widget. Engine off. EGT display on the right labelled EGT, CHT display shows as two solid bars across the two middle lines, temps on the left and CHT label lower left.
In the location mentioned in my post above, scroll down in the widgets list and select the EGT CHT widget. See the asterisk on the image. I hope that is clear.

Excellent. On my widget drop-down, I don't have "EGT CHT TEMPS" as an option... It's not on the list. This is good info... Let me play a bit more. Thanks, jnmeade!
