Knock Sensor / TPS Parameters

Knock sensor parameters.

 

parameters-knock

 

Always enable the knock sensor.

 

Flashing the MIL (check engine light) when the ECU detects knock will help alert you if the engine is knocking.

 

knock-settings

Use stock knock control logic - enables the stock knock control tables (knock ignition limit and knock retard tables).  Note that in versions of the software before 1.4.2 these tables were disabled by default.  If these tables are enabled, it is probable the ECU will  retard the ignition and some re-tuning will be required.

TPS range

 

This allows the throttle position sensor to be adjusted or re-scaled to suit slight variations in TPS sensor position or range. The normal TPS voltage range is 0.50V (closed) to 4.50V (open).

Minimum reading - is the default TPS reading when the throttle is fully closed. The Set button

 

Maximum reading - is the default TPS reading when the throttle is fully open.

 

Read - reads from the ECU and then sets either the minimum or maximum throttle to the current TPS reading. When setting the minimum reading, ensure the throttle is fully closed, when setting the maximum, open the throttle fully. This should be not be done with the engine running.

 

Defaults - resets the minimum and maximum settings to standard defaults.

 

Notes:

1. The minimum and maximum values are based on the default TPS range, and so will only be the same as the current TPS reading when the default TPS scale settings are in use.

2. This feature is not designed to correct a faulty TPS. The TPS must read at least 60% of the standard range.

3. If your TPS reads 100% when closed and 0% when open, re-pin the connector, swapping the VCC and GND pins.

4. If you generate TPS error codes then you have incorrect adjustments entered. Set the TPS settings to default, and re-adjust.
