Race Ninja engine performance summary showing an apex-to-peak pull from camera GPS with Alfano RPM on the same lap
Product Updates Karting Telemetry

The engine wasn't giving him the kick

Roman was driving well. The engine wasn't. We borrowed one and broke into the 39s. Engine insights now sit on the same lap as the camera so you can see a drop-off instead of guessing.

Karting Telemetry GoPro

Pick a HUD look. Then burn it onto the lap

DJI GoPro Karting

Your whole DJI session now counts, every chapter

No GPS on your camera? Upload your RaceChrono file instead

If your camera didn't record GPS, you can now bring your own. Upload a RaceChrono CSV alongside the video and you get lap times, overlays and coaching as normal.

A Race Ninja lap-by-lap graph showing kart engine pull and grip baseline fading across a session
Product Updates Telemetry

Your kart fades near the end of a session. Now you can see exactly why

Your kart is rarely as fast on lap 12 as it was on lap 3. Race Ninja's new lap-by-lap performance graph shows whether it's the engine, the tyres or the track losing grip, so you can stop guessing and start tuning.

Where am I losing time? How to find the corners that cost you

Every guide says brake later and hit the apex. None of them tell you which corner is actually costing you. Your own footage does. Here's how to read it and find your next few tenths.

GoPro Hero 11 GPS for racing: the value pick for telemetry

GoPro Tips & Guides Telemetry

Does the GoPro Hero 12 have GPS? (and what to do about it)

Straight answer: no. The GoPro Hero 12 Black has no GPS. And unlike a setting you forgot to switch on, there's nothing you can do about it. GoPro took the hardware out. This catches a lot of racers off guard. You upgrade from a Hero 11 expecting more of everything, and your telem...

Telemetry Overlay alternative for racers: when you want analysis, not just a HUD

If you've been using Telemetry Overlay, or you're weighing it up, here's an honest take on when it's the right tool and when it isn't. Telemetry Overlay is genuinely good at what it does. It reads GPS and sensor data off a GoPro, DJI, Insta360 or dozens of other devices and burns...

How to read a racing line from your GoPro footage

Everyone talks about the racing line. Far fewer people actually look at their own. The footage on your GoPro already holds it, you just need to draw it out. Because GPS records where you were several times a second, your exact path around the track is sitting in the video file. N...
