AEM 8 Channel K-Type Thermocouple EGT CAN Module - 30-2224

The AEM 8 Channel K-Type Thermocouple EGT CAN Module (Part # 30-2224) is a purpose-built data acquisition expansion module that lets you monitor up to eight exhaust gas temperature (EGT) or other high-temperature sources simultaneously over an AEMnet or CAN bus network. Whether you're tuning a turbocharged build, managing a multi-cylinder engine on a standalone ECU, or building a comprehensive motorsport data logger, this module provides the thermocouple channel density that serious performance applications demand — all in a single, tidy unit.

Key Features & Benefits

• Eight Independent K-Type Thermocouple Inputs: Accepts up to eight K-type thermocouple sensors simultaneously, allowing you to monitor EGT at every cylinder, across multiple turbine inlets/outlets, or at any combination of high-heat locations — without running separate analog wires to each gauge or ECU input.
• Miniature K-Type Thermocouple Connectors: Uses the industry-standard miniature K-type connector format, so the module is compatible with the wide variety of K-type thermocouple probes already available on the market. This keeps sourcing sensors straightforward and cost-effective.
• AEMnet / CAN Bus Output: Transmits all eight temperature channels over a CAN bus connection, making it natively compatible with AEMnet-based displays, data loggers, and ECUs. CAN integration means a single cable run carries all eight channels back to your dash or logger — dramatically reducing wiring complexity versus individual analog sensor runs.
• K-Type Suitability for High-Temperature Applications: K-type thermocouples are well-suited for exhaust gas temperature monitoring and other high-heat measurement tasks, making this module appropriate for forced induction tuning, race engine development, and track-day data acquisition.
• Sensors Sold Separately: The module is designed to work with common K-type thermocouple sensors, giving you the freedom to choose probes that match your specific bung size, temperature range, and mounting requirements.

Fitment

The AEM 30-2224 is a universal CAN bus expansion module — it is not vehicle-specific. It is compatible with any vehicle or application running an AEMnet or CAN bus-capable display, data logger, or ECU that can receive and interpret CAN data from an external expansion module. Common applications include turbocharged and supercharged performance builds, multi-cylinder race engines requiring per-cylinder EGT monitoring, and any motorsport or performance build where comprehensive temperature data is needed.

Because this is a universal electronics module rather than a direct-fit replacement part, fitment depends on your existing data acquisition or ECU ecosystem rather than vehicle year, make, and model. Verify that your display, dash, or ECU supports AEMnet or CAN bus input and can be configured to receive data from this expansion module before ordering. K-type thermocouple sensors (probes) are not included and must be sourced separately.

Frequently Asked Questions

Do K-type thermocouple sensors come included with the 30-2224?

No. The AEM 30-2224 module includes the eight-channel CAN expansion unit only. K-type thermocouple probes are sold separately. The module accepts common miniature K-type thermocouple connectors, so you can source probes suited to your specific installation.

What type of connector does this module use for the thermocouple inputs?

The 30-2224 uses standard miniature K-type thermocouple connectors on all eight inputs. This is the most common connector format for K-type thermocouple probes, making sensor selection straightforward.

How does the module connect to my AEM dash or data logger?

The module outputs data over AEMnet / CAN bus. It connects to your AEM display, ECU, or data acquisition system via the CAN bus, transmitting all eight thermocouple channels over a single network connection rather than requiring eight separate analog inputs on your dash or ECU.

Is this module vehicle-specific, or will it work with any car?

The AEM 30-2224 is a universal module, not designed for a specific vehicle make, model, or year. Compatibility depends on whether your existing electronics setup supports AEMnet or CAN bus communication. It is widely used across turbocharged builds, race cars, and performance applications of all kinds where multi-channel EGT or temperature monitoring is needed.
