XGauge

Last update: 2009/07/23

This page contains some information on extra commands and gauge options for the ScanGauge.

Use this data at your own risk.

The cars ECU supports the following PID's in mode 1:

PIDDescription
0x03Fuel system status
0x04Calculated engine load
0x05Engine coolant temperature
0x06Short term fuel trim
0x07Long term fuel trim
0x0BInlet manifold pressure
0x0CEngine revolutions per minute
0x0DVehicle speed
0x0ESpark advance
0x0FIntake air temperature
0x11Throttlevalve position
0x12Secondary air status
0x13Oxygen sensors available
0x14Oxygen sensor 1 voltage
0x15Oxygen sensor 2 voltage
0x1COBD standards that apply for this vehicle
0x21Distance driven with CEL on

There are other modes availabel besides mode 1. These are much less documented. In the table below you can find definitions for a number of gauges (for the XGauge menu) based on mode 1 and other modes.

Ofcourse you can choose your own name for the gauges.

Next to the XGauge there is also a possibility to send seperate commands from the ScanGauge. This is done from the CMDS menu, so not from the XGauge. Unfortunatly it is not possible to program names for each memory slot, but you can store them in memory. Make sure you issue the command you want!

CommandDescription
