Dragy Lap as an autocross data logging tool?

We took our 318,000 mile Acura NSX to a Porsche Club autocross and tested the Dragy Lap as a tool for autocross data logging and analysis. It was a fun day out playing with some of Stuttgart's finest and trying out another of Dragy Lap's feature sets with a custom point-to-point course.

Thanks for letting me know about this video. Great great stuff. I especially like how you walked the course to creat it and the data logging comparison. Im gonna keep an eye out on Amazon Prime Day and see id ut goes on sale.

[@JSAFIXIT]

This is some excellent info! I'll be buying one od these!

[@chuysaucedo7119]

I just finished your other video. Cool that you did this one too, as I also do autoX

[@LapoftheWorld]

Awesome. It feels like it should be useful. It's not going to be precise to the timing equipment (too many variables) but the important part is the accel/G data and *relative* times anyway.

I had no idea PCA ran at Pellissippi. SCCA got kicked out years ago when the "new" apartments complained about the noise.

[@LapoftheWorld]

Yeah, more than a couple of times this year. I'm not sure exactly how that happened, nor do I know the whole story behind SCCA losing the site, but it's possible the construction projects that the college started around that time may have also had something to do with it. Either way it was cool to revisit the old go-to site!
