Your phone becomes the dash

Every screen below is live CAN data in the free DashCAN app. Build your own layout, pick gauge styles and colors, then log everything you see.

Live dashboard: your channels, your layout, 50 updates a second.
CAN switches: race mode, presets and the pit-lane limiter from the phone.
Log viewer: record every channel, scrub the trace, export XLSX.

Is DashCAN OBD right for your car?

It plugs into the OBD port, but it is not a diagnostic scanner. It reads the CAN stream a standalone ECU broadcasts. Thirty seconds of honesty so you buy the right thing:

A great fit if

  • Your car runs a standalone ECU (like Ignitron) that broadcasts data as custom CAN messages
  • The OBD port's CAN pins are wired to the bus your ECU transmits on
  • You want plug-and-play: no loom changes, and it moves between cars in seconds
  • You want to log sessions and fire CAN switches without a laptop in the car

Not for you (yet) if

  • Your car is stock: factory-ECU OBD-II diagnostics (PID polling) is not supported yet
  • You expect fault-code scanning like a workshop diagnostic tool, which is not what DashCAN is for

Not an ELM327 dongle, even if it uses the same port

A generic dongle asks the car polite diagnostic questions. DashCAN reads the raw stream your ECU is already sending, and can talk back.

Generic ELM327 dongle

  • Polls a handful of OBD-II diagnostic PIDs, a few times a second
  • Factory-defined parameters only
  • Read-only, cannot switch anything
  • Standalone ECUs usually do not answer OBD-II requests at all

DashCAN OBD

  • Listens to raw CAN frames at full bus speed
  • Any channel your ECU broadcasts: 20 at once, 50 updates a second
  • Writes too: CAN switches trigger real functions in the car
  • Built for standalone ECUs from day one

Setup in four steps

The full guide with pictures and the per-ECU settings is on the First Steps page.

  1. 1

    Connect it to the car

    Plug it into the OBD port. The port's CAN pins have to be on the bus your ECU broadcasts on.

  2. 2

    Enable the CAN broadcast in your tuning software

    Each ECU has a short guide with the exact settings and pins. Ignitron users import two ready-made files.

  3. 3

    Install the free app and pair over Bluetooth

    iOS or Android. Grant the permissions the app asks for, then pair the interface.

  4. 4

    Pick your ECU in the app

    The channels show up live. Build your layout, then drive.

Works with

Ignitron ECU, ECU Master EMU, ECU Master EMU PRO, Emtron (needs the Apex), Haltech (needs the Apex), Hondata, MaxxECU, MegaSquirt, MoTeC (needs the Apex), rusEFI, Speeduino, Syvecs (needs the Apex), VEMS (needs the Apex), and any other ECU that can broadcast custom CAN messages.

This interface runs at a fixed 500 kbit/s. Emtron, Haltech, MoTeC, Syvecs and VEMS broadcast at 1 Mbit/s, which only the DashCAN Apex can read.

Which DashCAN is right for you?

Same app, same live data. Pick by how you connect, and whether you want lap timing built in.

Plug in before the next trackday.
