Accurate Coolant Temperature Data for Your Link ECU

Your ECU needs accurate temperature information to properly control fueling, ignition, cold-start enrichment, idle speed, cooling fans, engine protection strategies, and more.

The Link ECU Coolant Temperature Sensor (NTC1-8) provides a reliable coolant temperature input for compatible Link ECU installations and custom standalone engine-management systems.

Whether you're wiring a complete standalone ECU, replacing an existing sensor, or building a custom engine harness, this sensor gives your ECU the temperature data it needs to properly manage the engine.

Why Coolant Temperature Matters

Coolant temperature isn't just something displayed on your dash.

Your Link ECU can use engine temperature for critical calibration strategies including:

• Cold-start fuel enrichment
• Warm-up enrichment
• Ignition compensation
• Idle speed control
• Cooling fan activation
• Over-temperature protection
• Boost protection strategies
• Engine safety limits
• Datalogging and diagnostics

Incorrect or unstable coolant temperature data can cause poor cold starts, rich or lean operation during warm-up, incorrect fan operation, and other drivability problems.

NTC Temperature Sensor

The NTC1-8 uses an NTC (Negative Temperature Coefficient) thermistor.

As sensor temperature changes, its electrical resistance changes. Your ECU interprets this resistance through its analog temperature input and converts it into coolant temperature data.

When configured with the correct calibration in your Link ECU, this provides accurate temperature information across the engine's operating range.

A Small Sensor That Controls a Lot

A high-performance ECU can only make good decisions when the information coming into it is accurate.

The Link ECU Coolant Temperature Sensor (NTC1-8) provides one of the most important inputs in your engine-management system, allowing your Link ECU to properly compensate for engine temperature from a cold start all the way through full operating temperature.

For a clean, professional Link ECU installation, start with the correct sensors and give your ECU the data it needs.
