The window allows you the alter general KManager parameters and settings.
General Settings
Table change for increase and decrease keys - this sets the amount by while the ignition and fuel tables are altered when the increase and decrease keys are used to alter a selection in the Table Window The Cam Angle is always altered by 1 degree.
Rounding - currently unused.
File association - check this to associate calibration and datalogging files with KManager.
Automatic check for for new software version will check for software updates when KManager is first run, up to once per day. If an update is available then it may be downloaded from the Help menu.
Include beta software versions will additionally check for new beta software versions as well.
Note that even if 'Include beta software versions' is not checked, existing beta versions will be prompted to upgrade if a later production or beta software version exists.
Unit Settings
This tab contains settings for the unit display in the tables window.
Note that inch vacuum units and most pressure units are usually expressed based on atmospheric pressure rather than using an absolute base.
Display Settings
Main table tracing sets the color used to highlight the live tracing on the main tables (fuel, ignition, cam angle).
Parameter table tracing shows what values are being used for the parameter tables.
Changed Value Highlight
Values in the Table Window may be highlighted to show editing changes.
Also see Changed Value Highlight
Lambda Overlay Settings
This tab contains settings for the display of lambda readings.
Lambda Unit - the lambda unit used for display, either lambda (relative to stoichiometric) or air/fuel ratio.
Target Lambda - the target lambda for tuning over three different load areas. The Low Load Target Lambda is used when the engine load is below the low engine load value. The Medium Load Target Lambda is used when the engine load is between the low and high engine load values. The High Load Target Lambda is used when the engine load is above the high engine load value.
Apply Fuel Trims - adjusts the recorded lambda for short and long term fuel trims. This is so that fuel changes can be calculated when running in closed loop.
Calculate for each Cam Angle - when checked, records the lambda for each individual cam angle table, rather to collectively for all tables.
Minimum TPS - the minimum throttle opening before recording lambda. This is to prevent the recording of very lean lambda readings when the throttle is closed and the injectors are not firing.
Transition Delay - the delay between the throttle reaching the Minimum TPS and the recording of the lambda value. This is to allow the lambda to settle after the throttle is re-opened before taking any lambda readings.
Sensor Overlay Settings
This tab contains settings for a table sensor overlay.
Sensor - selects which sensor to overlay.
Calculate for each Cam Angle - when checked, records the sensor for each individual cam angle table, rather to collectively for all tables.
Conditions - determine what conditions must be met before the sensor is recorded.
Some sensors are translated when recorded:
| • | Knock Count is translated so that each time the knock count is increased the overlay cell value is increased by one. |
| • | Knock Level is translated to show the ratio of knock level to knock threshold. |
Wideband Lambda Input
This tab contains settings for the conversion of a wideband voltage input to lambda. Note that this is for display only - the ECU will use the primary o2 sensor for closed loop operation.
Lambda display selection - select either the built in wideband (available on PRB/PRC/PRD/PND/PNF ECUs), or an external wideband input via the ELD pin.
Quick select can use used to select the voltage/lambda conversions for some common lambda meters.
Voltage offset shifts the voltage/lambda conversion by the specified voltage in order to compensate for slight differences in voltage between the ECU and lambda meter.
The voltage/lambda conversion table is specific to each lambda meter. Details can usually be found in the lambda meter instruction manual.
Note that some wideband controller do not output enough current to the ELD pin to drive the voltage below about 2V. In this case, remove the two resistors R300 and R301 on the top side of the ECU circuit board.
Datalog Settings
Datalog AutoSave
Datalogs may be automatically saved when recording. The datalog is saved when datalogging or recording is stopped, or the ignition is switched off.
When saving datalogs the datalog filename is generated from a directory, filename prefix and filename suffix.
Import/Export Settings
Import/Export buttons allow for main settings to be saved and uploaded from any computer.
USB Driver Check
The check box named driver check enables and disables the balloon hint that pops out of the driver section of the status bar.
Above is what the status bar will look and give a message like this when the driver is not installed. Below is what it looks like when the driver is installed.
