MotoHawk:Blocks:Cylinder Knock PIPI Window Set

This MotoHawk® block sets the PIPI window locations for the selected knock device.

MotoHawk:Blocks:Cylinder Knock Sync Window Set

This MotoHawk® block sets the Knock Sync window locations for the selected knock device.

K

MotoHawk:Blocks:Knock IIR Filter Calibration

This MotoHawk® block will create a calibration specifically for a biquad flter coefficients with easy to read formatting.

Default Filter Coefficients: A vector of 20 biquad coefficients in the range of (-4,4).

Calibration Name: A unique name for the calibration.

Calibration Group: A group to associate the calibration.

MotoHawk:Blocks:Knock Calculation Complete Trigger

This MotoHawk® block triggers a Simulink Function-Call subsystem upon completion of a Knock Calculation Completion of the chosen device.

MotoHawk:Blocks:Knock Definition

This MotoHawk® block helps define the knock detection.

Cylinders: The number of cylinders that this device will read. Max 12.

Device Offset from TDC1: Offset from the TDC1 location for all angles of this device.

Default Sensor Gain: The default gain (1X or 2X) that the device will apply to the incoming signal.

Knock pin Select: A vector of 1's and 0's indicating the pin to use for each cylinder.

PROSAK Mode: See PROSAK CALSETUP description in the PROSAK manual.

MKIKS Development Enabled: Apply when needing MKIKS connected to an open module. Initialization will FAIL for a closed module.

Default Filter Coefficients: A vector of 20 biquad coefficients in the range of (-4,4).

MotoHawk:Blocks:Knock Filter

This MotoHawk® block updates the Filter Coefficients to the selected Knock Device. A vector of 20 int16 coefficients scaled in B2 (4/32768 per count) are required. Update occurs on trigger and if and only if one or more coefficients are changed. Note that Knock is invalid for the settling period of the filter after a coefficient change.

MotoHawk:Blocks:Knock Gain

This MotoHawk® block updates the KNKGAIN bit to set the sensor gain of the PROSAK device.

MotoHawk:Blocks:Knock Reference Filter

This MotoHawk® block filters reference coefficents in the range of [0,1). See PROSAK documentation for further details.

MotoHawk:Blocks:Knock Results

This MotoHawk® block retrieves knock calculations.

Parameters: Knock Device: Choose the device for which to retrieve results. Note that Knock Device 2 is only supported on 128 pin modules.

Firing Order: A vector of 12 elements in the range of [1,12] to set the firing order of the engine. This will re-order the outputs to be cylinder relative so that KnockEnergy[3] is for cylinder 3 and so-on.

Calibration Group String: A Calibration, CylFireOrderArr, is created for this block and can be adjusted in development units. This group string should be a pipe delimited string for the MotoTune group (i.e. 'Diagnostics & Protection | Knock | Knock Setup')

Outputs: Cylinder Trigger[12]: A vector of triggers that will occur upon availability of a calculation for a particular cylinder.

Last Computed Cylinder: A scalar that indicates the cylinder number of the most recently available data.

Knock Energy[12]: The output of the Knock Integrator for each cylinder. (See PROSAK manual)

RefEnergy[12]: The Reference Integrator output for each cylinder. (See PROSAK manual)

Ratio[12]: The Ratio output for each cylinder. (See PROSAK manual)

MotoHawk:Blocks:Knock Window

This MotoHawk® block sets the reference and knock window locations for the selected knock device.

P

MotoHawk:Blocks:PROSAK Filter Calibration

This MotoHawk® block will create a MotoTune calibration specifically for the PROSAK biquad filter coefficients with easy to read formatting. The output can be consumed by a Knock Filter block to update the filter coefficients in the device.

Default Filter Coefficients: A vector of 20 biquad coefficients in the range of (-4,4).

Calibration Name: A unique name for the Calibration in MotoTune.

Calibration Group: A group to associate the calibration with in MotoTune.

R

MotoHawk:Blocks:Read PROSAK Registers

This MotoHawk® block performs a raw read of the ProSAK registers and outputs them as a vector of 122 uint16 values.

V

MotoHawk:Blocks:VISTA Knock Definition

This MotoHawk® block helps define VISTA knock detection.

MotoHawk:Blocks:VISTA Knock Filter

This MotoHawk® block updates the Filter Coefficients to the selected Knock Device. A vector of 20 int16 coefficients scaled in B2 (4/32768 per count) are required. Update occurs on trigger and if and only if one or more coefficients are changed. Note that Knock is invalid for the settling period of the filter after a coefficient change.
