Track day data your GPS logger can't see.

Your current track data sucks. KAN_1 solves that.
KAN_1 is a CANBUS logger for most enthusiast performance cars that reads the factory bus at up to 100x faster than an OBD2 protocol dongle, and lets you overlay and review real data and driver inputs.

Track day data is broken. Data logging is broken. Data overlays are broken. Data review is broken.

This is why I built KAN_. So much about consumer track data is complicated, expensive, built in the early 2000s, or hard to use in so many ways. OBD2 data is slow, subject to Bluetooth issues and ends up rolling around your feet after the first kerb. Expensive GPS timers only know GPS and IMU data points, with no vehicle data, and are closed off systems. Trying to review your data on a phone screen between sessions is painful. Once you get home, creating a video to review or post your lap is a 100 step process, with dated systems that feel generations behind before you even try to match your footage to your data. Enough was enough, so I solved it.

What exactly does KAN_ solve?

OBD2 sucks, use CANBUS

The OBD2 protocol is slow, tedious and limited. CANBUS in most cars is already broadcasting the lot — up to 100x faster, with more data points.

Expose more data, improve the driver mod

More channels, real insight. See whether it was your braking, turn-in or throttle that found the time — proper data, proper insights.

Easy to extract, easier to use and better with friends

One clean, universal file per session. Review it in KAN_PITWALL or whatever you already use — KAN_ always plays nice.

GPS all the things

All data is synced through GPS time, so your footage and other loggers line up on their own. Match KAN_1 to footage from GoPro, phones, Insta360 and more.

Record your data, and show it off with video overlays.

The best way to improve your driving is to review your data, but the coolest way is to generate reactive video overlays that show exactly how you drove at any point of your lap. The clips on this page come from a skid pan day at RACQ, logged on KAN_1, and a session at QR on KAN_ prototype hardware. All data is UTC time-synced, extracted through the free online tool “PITWALL”, which keeps every file on your own machine, in your browser. When you have finished a session, take your data and your footage, and show off your driver mod however you like. Your data, your privacy — free, no signup, and nothing you load ever leaves your machine.

Introducing KAN_PITWALL — the best place to review and export your KAN_1 data.

KAN_PITWALL is the web-based software to help you go fast with review tools and/or make pretty videos like the one above. You can use PITWALL as much or as little as you like, or sync your data to other visualisers — it's always yours, and so is your data. Oh, and have I said that PITWALL is included for free?

Generate your video overlays

Gauges, traces and driver inputs rendered over your footage, no matter the source, aligned on GPS UTC rather than lining it up by eye. Free, in the browser.

Review your data

Scrub the traces against the track map, lap by lap. Adjust the start/stop location, or read elapsed time between any two points. Free, in the browser, nothing uploaded.

Export your CSV

Plain, unencrypted, engineering units, with both time_s and utc columns. No account, no cloud, no export queue. Ignore the tools entirely if you want to.

What's in the file

It physically cannot transmit to your car.

Rev C board, back side: the JP1 solder jumper labelled SOLDER FOR CAN TX ENABLE, left open from the factory so the CAN TX line is cut.

CANBUS can be a scary thing, so to be sure that KAN_ never interferes with the bus, it's not only software locked — the transmit pin is physically disconnected by a solder jumper. That makes KAN_1 a "listen only" device. Sleep soundly knowing that no matter what, no signals will ever flood the bus.
