It's possible, but I'm not sure it has much application outside drag racing and aviation? So it would be very low priority, given that there are already hundreds of enhancement requests to work through.

I hadn't heard of it myself either, but found "Density Altitude" and a reference to drag racing, and guessed that was it, with the mention of "race tracks". Supporting Cumulus is about 75% detective work :lol:

Sorry I should have explained what it was, as you now know .. We use this DA for racing, how it works is we take air temp and humidity = altitude

The higher the DA the slower the car will run I live in Texas and at times we race in altitude of 3200 feet due to the DA being so hi the tracks altitude is 900 feet as you can see the car would fight for air.
Allot of racers now have weather stations at the track this would be an awesome add on for me.

Thanks again Bill
