Knock Control Unit

Injector clogged under boost? Car detonates? Engine fried? Do not be that guy!

Retrofit your Honda B/D/H series ECU with a configurable knock control system.
Designed to be Integrated with Honda Tuning Suite (HTS), this system provides both reactive and memorized knock control and protection.

How it works

Knock detection on this device is completely automatic. It reads MAP or TPS and RPM to memorize the conditions under which knock occurred. It then sends out a 0 to 3.3v signal that corresponds to the intensity of knock per the given RPM/MAP/TPS condition. It will constantly monitor and when it detects that conditions are favorable it will reduce the output voltage appropriately. It's up to the user to configure their tuning software (HTS) to determine how many degrees of timing is reduced per volt. 

HTS Example

HTS has a dedicated Knock Control parameter. See example below where we specified timing removed as voltage increases (0 to 3.3V max, 5V range not supported by device)


Neptune Example

We can use Neptune's Sensor Adjustment option (used for flex fuel) as knock control input. See example below: 

Speeduino Example

We can use the flex fuel input on a Speeduino ECU as knock control. For this to work you must NOT connect the RPM source. It will provide an overall broad knock protection for situations such as when fuel quality gets poor or intake temps or coolant temps are very high. 

Knock Light Output

Need an LED indicator for knock? Configure the output to use as an LED indicator for knock. a 150 Ohm resistor is required.

 

What's Included

  • 1x Knock Control Unit
  • 1x Bosch Knock Sensor

FAQ

  • Can this work with other ECUs? Yes. As long as the ECU has a mapping for analog voltage input and timing retard per volts.
  • Does this produce audio recording or logs? No, that feature is reserved for the Knock Monitor Pro.
  • How many inputs does this device require? Requires 3 inputs: Knock sensor, MAP (or TPS) and RPM.
