Jeff,

I have two IAT probes on my TSIO-550 powered Legacy. It reads out on the
Chelton (there is only one value displayed at a time). I have a toggle
switch that selects which probe I want to display. 

One is placed  after the right turbo, but before the air passes through the
intercooler. The other probe is located in the upper deck. 

I use a GRT EAU to feed information to the Chelton. There is a Chelton
software problem. The EAU temperature says carb temp. When the IAT temp on
the Chelton reaches 127 degrees F the display turns red, and as the
temperature rises beyond 126 degrees F the displayed value has a minus sign
in front of it and decreases in value. I.E., 127 degrees would be displayed
as -125 degrees F; 128F displayed as -124F. I have discussed the issue with
the experimental folks at Chelton, but they didn't think there was a high
probability that the needed software change would be forth coming any time
soon.

I don't use it for LOP operation though.

TSIO550...does anyone use an Induction Temperature sensor to monitor air
temp coming through the throttle?  Do you find it useful as you explore LOP
operations?  Air mass, air temp, fuel flow...a more precise representation
of A:F ratio.
