There is a free air density calculator in there which brings me to a question.
I am trying to build up a map database for my bike at El Mirage but admittedly, I don't know what's important.
What I have been doing is making a pass and data logging the A/F and noting the density altitude, then saving that map relative to that density altitude. I end up with a bunch of files that say "13.0 at 5,000 D/A" with the D/A being different.
Say I make a pass and the A/F is 13.0 and that's where I want it and the density altitude is 5,000 feet. next month, if I am getting ready to make a pass and I see the density altitude is going to be near 5,000 feet, I would select the map closest to that D/A. However comma, isn't it possible to get a different density altitude with different combinations of humidity, pressure, and temperature?
This is too confusing... what happened to light the fuse and get on it and ride?
I guess my main question is, what parameters are important to log for tuning. If I had to pick three, what would they be?
