Add Reliable Knock Detection to Your Link ECU Setup
Protect your engine and give your tuner the data needed to build a safer calibration with the Link ECU Knock Sensor with Matching Connector (KNS).
Designed for use with compatible Link ECU engine-management systems, this knock sensor detects engine vibration associated with detonation and allows the ECU or tuner to monitor what is happening inside the engine under load.
For turbocharged, supercharged, high-compression, or high-performance engines, proper knock monitoring is one of the most valuable tools you can add to your engine-management system.
Why Knock Detection Matters
Detonation can quickly damage pistons, ring lands, bearings, head gaskets, and other expensive engine components.
And the problem is—you can't always hear it from the driver's seat.
A properly installed knock sensor allows your Link ECU system to monitor engine vibration so your tuner can identify knock activity during calibration and configure the appropriate knock-control strategy.
This is especially important when tuning:
Turbocharged engines
Supercharged engines
High-compression engines
Pump-gas performance builds
E85 and flex-fuel applications
High-horsepower street cars
Race engines
Perfect for Custom Engine Builds
The Link KNS is an excellent solution when you're building a custom standalone ECU installation and need to add knock sensing to an engine that doesn't already have the correct compatible sensor.
It's ideal for:
Engine swaps
Custom Link ECU installations
K-Series builds
Honda and Acura applications
Nissan and Infiniti builds
BMW performance engines
GM engine swaps
Turbo street cars
Drag cars
Road-race cars
Matching Connector Included
There's no need to hunt down the correct electrical connector separately.
The KNS includes the matching connector components, making it easier to integrate the sensor into your custom engine harness.

Give Your Tuner Better Information
Making power isn't just about adding boost and ignition timing.
The goal is to find the calibration the engine actually wants while staying away from damaging detonation.
With a properly installed and configured knock sensor, your tuner has another critical source of information when adjusting ignition timing, boost, fuel, and other calibration parameters.
Protect the Engine You've Invested In
You've already spent money on the engine, turbo, fuel system, ECU, and supporting modifications.
Don't leave knock detection out of the equation.
The Link ECU Knock Sensor with Matching Connector (KNS) provides a professional solution for adding knock monitoring to compatible Link ECU installations.
Knock sensor performance depends heavily on sensor mounting location, mounting surface, torque, wiring, ECU configuration, and knock frequency/filter setup. Always follow Link ECU's recommendations for your specific ECU and engine combination.
