Figure 2 – Data Logging Chart Display

The following additional functions are available from the Edit menu:

BLM Cell Display – shows the active cell in terms of RPM and TPS percent at the cursor position. TPS percent is compensated for idle air. This function is useful for determining what fuel table cell is active at any given point in time.

Gear Ratio Display – shows the calculated gear ratio (RPM/KPH) at the cursor position. This function is useful for determining the 6th gear ratio required for Module Parameter setup in PC Link TCFI IID for 2007 models with six speed transmissions and a 6th gear indicator light.

Units Selection – allows selection of MPH or KPH units for vehicle speed display.

IAC MANUAL OVERRIDE

The IAC Manual Override command on the Communications menu allows you to manually override the idle air control stepper motor position while the engine is running. This command is primarily used to calibrate larger aftermarket throttle bodies, but can also be used as a diagnostic aid.
