DashCAN EGT to CAN
Eight exhaust temperatures on the CAN bus
An exhaust gas temperature bridge: eight K-type thermocouples in, one CAN bus out. Per-cylinder EGT in real time, logged with the rest of your data, and everything the DashCAN interface does is built in.

What it does
Exhaust gas temperature is the earliest warning an engine gives. This bridge puts it on the same bus and in the same log as everything else.
- 8 K-type thermocouple inputs
- One per cylinder on an eight-cylinder engine, or pre and post turbo, or wherever you want to watch exhaust temperature.
- Per-cylinder EGT in real time
- Ten readings a second per channel, live on the phone, so the cylinder running hotter than the rest shows up right away.
- Accurate where it counts
- 16-bit converters and the cold junction measured right at the terminals give 0.1 °C resolution and ±2 °C from the electronics, down to ±1 °C with per-channel calibration.
- CAN bus output, your way
- Set the bitrate, message IDs, frame layout and send rate to match your ECU, and switch the 120 Ω termination on or off from the app.
- Set up over Bluetooth
- Configure it, calibrate each channel and watch the live temperatures in the DashCAN app. No laptop and no config cable.
- Everything the DashCAN interface does
- Live gauges, CAN logging with XLSX export and CAN switches over Bluetooth, the same as every DashCAN interface.
- Built for standalone ECUs
- Works with any standalone ECU that reads custom CAN messages, so the ECU can use EGT for protection and logging.
- Sealed power and CAN connector
- Power and CAN come in on one Deutsch DTM plug, and the probes on pluggable screw terminals, so the box comes out without unwiring anything.

Accuracy at 1000 °C. The electronics figure covers the board alone; the system figure adds a class 1 K-type probe. Cylinder to cylinder, matched probes read within about ±1 to 2 °C of each other, which is what matters when you hunt for the hot one.
Choosing and fitting the probes
The box measures precisely, but a thermocouple reading is only as good as the probe and the wire behind it.
Do
- Use ungrounded (insulated junction) K-type probes
- Run K-type thermocouple extension wire all the way to the box
- Class 1 probes for the best absolute accuracy
- 3 mm exposed tip probes for the fastest response, about 0.5 to 1 s
- Mount every probe at the same distance from its exhaust port, so the cylinders compare fairly
Avoid
- Grounded junction probes: they tie the inputs to the chassis and upset the readings
- Copper extension cable: it moves the cold junction and can read tens of degrees off
- Thick sheathed probes when you want to see fast changes: 6 mm sheaths take 3 to 10 s to follow
Eight exhaust temperatures, one CAN bus.
