The racer is one step closer to setting up a tuning plan for density altitude like we wrote about throughout our technical manuals; the racer can log onto airdensityonline.com and get current air density and density altitude for many race sites throughout the US; and soon density altitude forecasting for your day before planning. When we raced, we would look up the weather forecast and manually calculate density altitude for the following day, using the math in our tech manuals. That is soon to be automated in the site link.
