Traction control requires the addition of an interface module to the wheel speed sensors, available from Hondata as Traction Control.
Important: Before the Traction Control options will be displayed in SManager, the Traction Control module needs to be plugged in while SManager is running. This only needs to be done once.
Traction Control options are available from the Traction Control tab in the Parameters window..
Input source
This selects the traction control analog voltage input pin.
Parameters
Traction Control parameters determine when traction control operates, and what the input error condition is.
Minimum rpm determines the minimum engine speed the traction control will operate at. Set this above idle and below the minimum speed which you would expect wheel slip.
Voltage offset is the input voltage offset from the Traction Control module. Note that any non-zero value indicates a difference in ground potential which should be fixed. See the traction control software test tab for information about how to generate a test voltage output.
Max input voltage is the maximum voltage the ECU will accept before generating an error condition. The effect of this settings depends on the input pin used. Some pins, like the ECU ELD pin, will read around 4.3V with nothing connected to the pin. In this cause, the ECU needs to detect that the Traction Control module is unplugged or not operational, and not to apply limiting actions to the engine. Set the Max input Voltage below the pin unplugged voltage, and above the Traction Control maximum output setting.
Actions
These control what actions the ECU takes when excessive wheel slip spin is detected.
Ignition retard is primarily used to reduce engine output, then an escalating sequence of soft rev limits are used to further reduce engine output.
Ignition Retard sets the amount of ignition retard when wheel slip occurs. Values are interpolated between columns.
Rev Limiter sets any rev limiter based on wheel slip, where 0% = no rev limiter, 100% = a full cut and values in between 0% and 100% are progressive rev limits. Values are interpolated between columns.
