TOOLS FOR RACERS WHO TRAIN SYSTEMATICALLY
Plan track days, capture what happens on track, understand the data, carry the lessons forward. An end to end system for working towards your goals.
We believe in the process

Our core belief is that working systematically and with routine is the road toward your goals. There’s no magic bullet to winning, but if you keep learning, you’ll be ready when racing throws something unexpected at you.
With TestLogger, you can log everything from lap times to sensor data, and use it to learn at any scale, from a single corner to a full season’s progress. Past sessions stay easy to revisit, so you can build on what worked and avoid repeating what didn’t.
Coach TQ analyzes your runs, helps you plan the next session, and keeps your work structured between track days. The more data you give it, the more specific the guidance becomes.
Each tool also works on its own. You can use TestLogger Manager to track setups and runs by hand, even without any data logging hardware.

Three products, one system
Each one works on its own. Together they cover the full cycle from planning a session to carrying lessons into the next one.

Get Started
From signup to your first systematic session
Create a free Manager account in under a minute. After your first login, the onboarding wizard sets up your first event, session, and goals, so you have a working structure from day one.
From there, the Treasure Map walks you through the full process — from the basics of organizing data, to running a systematic test day, to working with a team. It’s there when you need it, not in your way when you don’t.


Go deeper WITH DATA LOGGING
Add sensor data to your runs to really understand where you lose and gain time, and most importantly, why. Split times, steering and throttle usage, wheel speed, RPM, accelerations. Race-legal under IFMAR, ROAR, and EFRA.
Three bundles to choose from, each with everything you need to start logging on the car.
- Base bundle gets you started with minimum sensors to analyse the driver and the car.
- Full bundle gives you more sensors like three beacons and wheel speed.
- Double bundle is the best option if you want to add logging to two different cars.
