Switched +12 V and ground
Pin 1 to switched ignition +12 V. Pin 6 to chassis ground. Don't use a permanent +12 V or the device stays awake with the key off.
Before you start
What you need.
- Tracktuned Connect device
- Switched 12 V supply in the car
- Access to the ECU's CAN bus
- iPhone (iOS 16 or later)
Wiring
Four wires. Two buses.
Connect ships with an automotive plug already crimped to a metre of wire. One CAN bus carries the keypad, the other reads gauge data, or run both on the same bus if your ECU only has one. Pin numbers are stamped on the connector body. View from the wire-entry side.

CAN1: pins 2 (H) + 3 (L). CAN2: pins 4 (H) + 5 (L). Use whichever bus your ECU lives on. If your ECU has two separate buses (e.g. one for keypad input, one for broadcast data), use both.
Tap into your ECU's CAN
Find your ECU's CAN H and CAN L pins (your ECU manual lists them). Wire them to pins 2 + 3 on Connect for CAN1, or pins 4 + 5 for CAN2.
Verify before you turn the key
A misrouted +12 V into a CAN line will damage every device on the bus. Disconnect the vehicle battery while you wire it. Multimeter check the plug before you plug it in.

Connect's WiFi
Network
Tracktuned Connect
Password
tracktuned
Connect stands up its own WiFi as soon as it powers up. Your phone joins this network directly. No internet, no cloud, no pairing button.
iOS
Download on the App Store
Sign-in is optional. The app works fully offline against the device; sign in only if you want layouts synced across phones.
Turn the key
Connect boots in a couple of seconds. The WiFi network appears.
Join the WiFi
On your phone: Settings → WiFi → Tracktuned Connect, password tracktuned. iOS may warn "No internet": that's fine, it's a direct link to the device.
Open the app
First launch walks you through Welcome → WiFi → Detect → Name. By the end you have a named layout that auto-loads every time you connect to this car.
Pick your ECU
CAN profile.
Connect detects your ECU and sets the right CAN profile automatically. If you want to change it later, it's in the app's settings.
| ECU | Profile | Configure with |
|---|---|---|
| Haltech Elite (any) | haltech | NSP (Haltech) |
| ECUMaster EMU BLACK | ecumaster | EMU Black Client |
| CANTCU / Blink Marine PKP | cantcu | CANTCU Configurator |
| Turbolamik | turbolamik | Turbolamik tool |
Troubleshooting
Something not right?
WiFi network doesn't show up.
Check the LED on the device. Confirm ignition is on (Connect needs switched +12 V, not key-off). Give it a few seconds after power. If still nothing, multimeter check pins 1 and 6 at the plug for +12 V across the device.
App can't find the device.
Confirm your phone is on the Tracktuned Connect WiFi (not your home WiFi or cell data). iOS sometimes silently switches back to a network with internet. Check Settings → WiFi.
Connected, but no gauge data.
Your ECU isn't broadcasting on the bus you wired to. Try the other CAN bus (swap to pins 4+5 if you wired to 2+3). Or your ECU's CAN broadcast isn't switched on: check your ECU's CAN setup in its tuning software.
Buttons send but the ECU doesn't react.
For Haltech and similar: the ECU needs a CAN keypad enabled in its config. NSP → CAN setup → enable "Generic CAN Keypad" or your ECU's equivalent. The keypad CAN ID is in the spec table below if you need to map it manually.
Phone keeps disconnecting.
Don't sit on top of the device: WiFi range is line-of-sight. Move the phone closer for testing. The app reconnects automatically when the signal returns.
I bricked the wiring.
Disconnect the loom. Email us at [email protected] with photos of how it was wired. We'll work out what's salvageable.
