Displays the current activity of the Knock Control system. The following states may be displayed:
·Active - The knock control system is working.
·Lockout - RPM Low - RPM is below the RPM Low Lockout setting.
·Lockout - RPM High - RPM is above the RPM High Lockout setting.
·Lockout - TPS Low - Throttle position is below the TP Low Lockout setting.
·Lockout - TPS Delta - The throttle has been suddenly opened or closed, knock Control is disabled during this time.
·Lockout < 500 RPM - Engine speed is less than 500 RPM, knock Control is disabled during cranking.
·Error - Knock control has failed to initialise, try restarting the ECU, contact tech support if the problem persists.
·Startup Lockout - The knock system is disabled during engine startup.
·OFF - Knock control turned off.
·Disabled - The Disable Digital Input is active and so knock is not operating at this point in time.
·Lockout - Launch Control - Launch Control is armed and it's limit is active Knock Control is disabled.
Note: This runtime is only used when using one of the Normalised knock modes (Normalised Ign, Normalised Fuel or Normalised Ign & Fuel).
This runtime status indicates whether the Knock Control system is currently treating the engine as stable or transient.
·Stable - All of the delta level settings are below their respective delta runtimes. The Knock Control considers the engine load and rpm to be stable.
·Changing RPM - The Engine Speed ROC is greater than the RPM Delta Level. The Knock Control considers the engine to be in a transient condition.
·Changing Load - The TPS Delta is greater than the TPS Delta Level OR MAP Delta is greater than the MAP Delta Level. The Knock Control considers the engine to be in a transient condition.
·Changing RPM & Load - The Engine Speed ROC is greater than the RPM Delta Level AND (The TPS Delta is greater than the TPS Delta Level OR MAP Delta is greater than the MAP Delta Level). The Knock Control considers the engine to be in a transient condition.
When Knock Control considers the engine to be in a transient condition the normalising filter rate is been changed to the Delta Learning Rate value and the Knock Threshold Table value is multiplied by the Delta Threshold Gain.
The current value from the Knock Threshold Table. This is the level the knock signal will have to exceed before the knock ignition or fuel trim(s) are applied.
The general knock signal level of all cylinders combined.
Note: This runtime is only used when using one of the Normalised knock modes (Normalised Ign, Normalised Fuel or Normalised Ign & Fuel).
Displays the normalised version of Knock Level Global.
Displays the current level of Knock, negative values if the Knock level value is below the Knock Threshold and positive values if it is above.
Ignition Trims, Fuel Trims and Ignition and Fuel Trims Modes:
Knock Level Detected = Knock Level Global - Knock Threshold
Normalised Ign, Normalised Fuel and Normalised Ign & Fuel Modes:
Knock Level Detected = Knock Level Normalised - Knock Threshold
Knock Engine Speed ROC, Knock TPS Delta & Knock MAP Delta
These three runtimes values are the values from Engine Speed ROC, TPS Delta & MAP Delta respectively with the filtering specified by Knock Engine Speed ROC Filter Level, Knock TPS Delta Filter Level & Knock MAP Delta Filter Level respectively. These values are used to determine when the engine is in transient conditions which can trigger a higher knock threshold and faster update rate as well as changing the Knock Load Status.
Note: these values are 0 when Knock Mode is not set to one of the normalised modes.
The individual knock signal level for this particular allocation.
The total number of times knock level has exceeded the knock threshold for all allocations. This will equal the sum of all the individual Knock Counter X runtime values.
The number of times the knock signal for this allocation has exceeded the knock threshold level
The amount (degrees) of ignition trim applied to the ignition angle of allocation X when the ECU, the value comes from the Knock Ignition Trim X Table.
The amount (%) of fuel trim applied to the effective PW of allocation X when the ECU, the value comes from the Knock Fuel Trim X Table.
