Plug into the car
Four wires to the loom: 12 V, ground, CAN-H, CAN-L. Sealed automotive plug.
The hardware
Small, sealed, ready to wire.
What it is
One device. Six jobs.
01
Two CAN buses in one box
ECU and gearbox controller on separate buses, both talking. One install, one device. CAN1 is FD-capable for the modern stuff.
02
Your phone is the keypad
15-button wireless keypad with live LED feedback. Boost maps, launch control, traction, fans. Free app, iOS + Android.
03
Apple Watch on your wrist
Four buttons live on your wrist. Live LED feedback from the ECU. One-handed taps through racing gloves. No looking down.
04
Data logger built in
Every CAN message saved to your phone. Drop the file into your favourite data viewer when you're back at the workshop.
05
Sealed for the car
DTF13-6P automotive plug. 9 to 24 V switched. Reverse-polarity protected. Rated to 85 °C. Real motorsport-grade kit, not a hobby PCB in a 3D-printed shell.
06
UK-built, lifetime updates
Designed and built in the UK by people who actually race. Over-the-air firmware updates for life. No subscription, no cloud, no telemetry.
On your wrist
Apple Watch keypad.
The four buttons you reach for most (boost map, traction, anti-lag, launch) live on your wrist. Live LED feedback from the ECU. One-handed taps through gloves. No looking down.
- 1–4 button keypad. Mirrors the same buttons you've configured on the phone: toggle, momentary, hold, rotary.
- Live ECU LEDs. The Green / Amber / Red pips show what the ECU is reporting back, just like the phone.
- Haptic by mode. Different feedback weight for toggle, momentary, hold, so your wrist knows what just happened without you having to look.
- Reconnects automatically. Loses signal in the pits? It resyncs the moment the phone's Bluetooth link to Connect comes back.
