You can't rent a race engineer. So we built one.

Every fast pro driver has two people: a coach in the right seat, and a race engineer buried in the data between sessions. Coaching you can get — every Chin and JTI weekend has excellent instructors, and you should use them. The engineer is the half nobody rents for a track day. That's the part we do.

Send us your data and we'll write up your sessions — then tell us where we got it wrong, and we'll fix it. That's the whole beta.

Standing challenge: anyone out there under 1:33 at Road Atlanta? Our fastest logged lap is a 1:33.158. Beat it and we'll go find out why — corner by corner, against the camber of the road itself.

Chat with your laps

The data on this site is the public view. Drivers on the platform also get a private connector for Claude or ChatGPT — ask questions in plain English, get answers from your own telemetry.

1. Send your data

Email your lap-timer export after a track day — Harry's Lap Timer, RaceBox, or Porsche Track Precision.

2. We load it

Laps are normalized, quality-checked, and ready to query in about 20 minutes.

3. Ask anything

“Walk me through my fastest lap, corner by corner — where am I giving up time?”

“Your fastest lap was a 1:40.200 — top speed 146 mph at the end of the back straight, 138 → 52 mph into the chicane at 1.12 g. Your session bests dropped ten seconds across the day.”
