Here is a sample of the screen where you can record up to 3 data points. I picked (Blue=RPM) (Green=Boost) (Gray=Timing Advance). I wanted to see what the timing is doing on my runs. Although its only a pull through 1st to the end of 2nd gear you can see it does seem like it pulls about 3deg of timing at the top of 2nd? I would like to eventually hit the track up with this and run with and without my meth to see if there is a difference there.
