Speed Unit and Temperature Unit – Use the pull down menus to select Imperial or Metric units. Data Display Settings – When the Data Display Basic Function is active, the computer screen becomes a full screen gauge panel. The Data Display Settings panel allows the user to determine what each of the 12 gauges will display. Note that all 12 gauges must have a selection. Also note that not all listed gauges are supported for all ECU / vehicle types. Selecting a gauge that is not supported, such as EGT when no EGT is fitted, will cause an error and all gauges will display 0. (Multiple gauges may monitor the same parameter.)

Duty Cycle – Duty cycle of fuel injectors as a percentage of total available cycle time. (left bank if engine is a V6 or V8 and configured to control the banks individually). RPM and Injector Time must also be selected. Duty Cycle is calculated from Injector time. Injector opening time is calculated by the ECU based on an engine load. It’s not a measured value and it might not be achievable given the RPM. Due to this, it’s not uncommon to see Duty Cycle above 100%. uty Cycle Right Hand– Duty cycle of right bank fuel injectors as a percentage of total available cycle time when engine is a V6 or V8 and configured to control the banks individually). RPM and Injector Time Right Hand must also be selected.

O2 Sensor B1 – Percentage of full scale of the oxygen sensor on OBDII compliant cars located after the catalytic converter. (left side if two sensors are configured as in the case of dual exhaust systems). O2 Sensor B2 – Percentage of full scale of the right side oxygen sensor on OBDII compliant cars, located after the catalytic converter when dual sensors are configured as in the case of dual exhaust systems. Test for live registers – This button queries the ECU for active registers. When the query is complete, select Update Gauge Selection to populate the gauge drop down lists with only those gauge choices supported by the ECU.
