A Good Day to Drive

I drove the car quite a lot today since the last post. I probably drove a total of about 15 miles, with the longest drive about 6 miles (I say "about" because I have not yet calibrated the electronic speedo. Tomorrow...). As a first step in deciding how to attack the acceleration parameters, I took a fairly long data dump - here is a chart showing some of the data from 2 minutes of that drive. First thing that jumps out is that the pedal is only pulling the throttle about halfway down. But it's not yet clear whether fixing that (or tweaking a multiplier variable in the controller) will help.
