Aim CANKey CAN Bus Data Logger, Sniffer & Streamer

The Aim CANKey is a compact, versatile CAN bus data acquisition device designed for motorsport engineers, vehicle developers and racing teams. Offering four operating modes in a single unit, CANKey allows users to record CAN bus traffic, replay captured data, acquire information directly from an ECU or extend the recording memory of a compatible Aim data logger.

Whether you're analysing vehicle communications, diagnosing ECU signals, developing electronic systems or reviewing performance data, CANKey provides a flexible solution for capturing and managing information from your vehicle's CAN network.

Configured through Aim Race Studio 3, CANKey records data to its 4GB internal memory, with additional recording to a removable USB memory drive when connected. Its compact aluminium construction, IP67 waterproof rating and lightweight design make it suitable for demanding motorsport environments.

CAN Sniffer mode records every CAN frame travelling across the connected bus, complete with microsecond-resolution timestamps.

This allows engineers to investigate the information transmitted by an ECU or vehicle electronics without needing to interpret the messages during recording.

Recordings can be exported in CSV or ASAM MDF4 formats for analysis in compatible third-party software, alongside Aim's native recording format.

CANKey also offers a silent monitoring option, allowing CAN traffic to be observed without acknowledging or transmitting frames onto the bus.

CAN Streamer mode allows previously recorded CAN bus traffic to be transmitted back onto a CAN network while preserving its original timing.

This is particularly useful for bench testing, electronics development and troubleshooting, allowing engineers to recreate recorded vehicle communications without requiring the original vehicle to be present.

Recordings can be played once or continuously in a loop, providing flexibility for testing and development.

In ECU Logger mode, CANKey communicates with an ECU using a supported Aim ECU protocol, recording selected channels for subsequent analysis.

Up to 120 ECU channels can be enabled, depending on the selected protocol, allowing users to capture a wide range of available engine and vehicle information.

Recorded sessions can be downloaded and analysed using Race Studio 3, providing familiar data analysis tools for existing Aim users.

CANKey can also operate as an additional recording memory module for compatible Aim data loggers.

When connected to the logger's Aim CAN network, CANKey automatically receives the master logger's configuration and records the selected channels whenever the master begins recording.

Files are saved using matching session names, making it easier to identify and manage recordings across both devices.

Built around a lightweight aluminium housing, CANKey is designed to withstand demanding motorsport and automotive environments.

Weighing approximately 50g and featuring IP67-rated protection, the compact device can be installed using screws, straps or Velcro.

An optional automatic switch-off function can also help reduce power consumption when the CAN bus is inactive, with configurable CAN activity wake-up functionality.

CANKey is fully configurable through Aim Race Studio 3, allowing users to select operating modes, manage recording conditions, monitor CAN traffic, download sessions and update device firmware.

The software provides live CAN message monitoring in Sniffer mode and live ECU channel values in ECU Logger mode.

With automatic baud-rate detection available in Sniffer mode, CANKey can identify the connected CAN network's communication speed, simplifying the configuration process.
