Oil Temp widget behavior

[tomkk]

My Oil Temp widget is defined to have 4 ranges (actually 5 but one is marked as Not Valid). I have two issues/questions:

At Startup the widget shows 5 ranges. From the bottom: Yellow, Blank (a range whose color is black), Green, Yellow, Red:

At some temp, I missed the exact temp, the widget reverts to the expected 4 range Yellow, Green, Yellow, Red display:

Also, the "Needle" (the white bar that moves up the display, doesn't move off the bottom "peg" until the temp reaches about 103 deg or so. The bottom range for the widget is defined as 80-120 deg so I would have expected the needle to start moving above 80 deg.

I have seen the first of those in 3 other RV-12s. I don't see anything in the widget config that would cause either of those. Any ideas?

Here's the relevant section of the dfg file:
c37_p7={
valid=1
name=OIL
id=ROTAX CHT OR OIL (801-10-1)
alarm_type=SELF-CLEAR
range={
max_display=260
min_display=80
range1_valid=0
range1_top=80
range1_bot=75
range1_name=R1
range1_color=RED
range2_valid=1
range2_top=120
range2_bot=80
range2_name=R2
range2_color=YELLOW
range3_valid=1
range3_top=230
range3_bot=120
range3_name=R3
range3_color=GREEN
range4_valid=1
range4_top=248
range4_bot=230
range4_name=R4
range4_color=YELLOW
range5_valid=1
range5_top=260
range5_bot=248
range5_name=R5
range5_color=RED
}
show_units=1
}

You're seeing the special oil temperature behavior that is specific to Rotax engines. It's triggered by specifying having a Rotax engine in setup. It changes both the tach and oil temp red/yellow zones as documented in the manual (and on other threads in this forum) to discourage running hard when cold (reduced redline) and to encourage you to get the oil hot (the black zone in oil temp backfills to green when you get to a certain temp, indicating you've gotten the oil suitably hot per Rotax's spec)

Thanks. That temp is 122 deg F though. RPM shouldn't exceed 2500 until the oil temp is greater than 121 deg. The tach changes correctly at that temp but the oil temp widget changes at some significantly higher temp, well over 122 deg.
