I had a chance to try out my performancebox at laguna seca yesterday in my stock engine 97 with megasquirt pnp and it's pretty cool to look through the results. I graphed 3 laps from the same session. The red/blue lines are with little to no traffic (1:59 lap times)and the green one is where I got stuck behind someone who couldn't be bothered to give me a point by (2:07 lap time). x-axis is distance from the start position I picked and the y-axes are speed and g's. I was marginally faster speed wise from turn 2 to turn 6 on the blue lap which was enough to cover the big speed difference after the corkscrew on the red lap. Cool stuff. Now I need to cut and paste together a bunch of laps and find a 1:55.

 

very consistent
