WSCAN Atmospheric Sensor, CAN Output
Delivers atmospheric conditions, measured or calculated, as CAN channels. The channel set is listed in each ECU's application note.
Every unit ships with its own calibration record, tied to its serial number.
- Supply voltage
- 4.9-28 V
- Typical quiescent current
- Approximately 6 mA
- Firmware validation suite
- More than 3,100 tests
Overview
On a CAN-native ECU or dash, the engine, the chassis and the driver inputs all arrive on the bus. The air the engine breathed usually does not: it is read off a separate instrument and kept somewhere else.
WSCAN puts the atmospheric conditions on the same bus, so the ECU or logger records them with the rest of the data.
Patent Pending
Autonomous ECU Recognition
Connect it to a supported ECU's CAN bus and it recognizes the ECU and configures itself, with no programming or firmware changes on the sensor.
Not every ECU lets users send configuration messages to devices on its CAN bus. On those ECUs, WSCAN configures itself.
Recognized automatically: Holley HP, Dominator and Terminator X; Haltech Elite and Nexus series.
Integration
Supported ECUs
- Holley HP, Dominator and Terminator X
- MoTeC M1
- FuelTech FT700
- Haltech Elite and Nexus series
ECU-side setup is done in the ECU's own software, following that ECU's application note.
Additional CAN protocols are written in the firmware and can be enabled to a customer's requirements before shipment; contact us for the full list.
DBC files are available to customers on request.
Same atmospheric conditions, analog or CAN: choose the interface that matches the car. WSANA Atmospheric Sensor, Analog Output
Built and Proven
- Every WSCAN firmware build that ships has passed our validation suite: more than 3,100 tests to date. New feature sets get their own tests before they ship.
- Every unit is individually calibrated and tested before it ships.
- Final assembly, programming, calibration and test are done in-house on every unit.

When Something Goes Wrong
Detects CAN wiring faults and recovers once the fault is corrected, including a CAN bus unplug / replug with power on, without a power cycle.
Status LED
| LED | Meaning |
|---|---|
| Red-green-blue | Start-up self-test |
| Green blink once a second | Normal operation, telemetry transmitting |
| Blue blink | Communication fault, recovering once corrected |
| Solid white | Internal fault |
| Solid red | Hard fault |
Per the application notes.
