Advanced Options:
The Advanced Options menu allows you to make adjustments beyond the basic settings configured by the Setup
Wizard.
Advanced Setup 1:
SPEEDO PPM:
Different speedometers require different numbers of pulses per mile (PPM). If the wrong PPM
setting is used, the speedometer readings will be off by a large margin. The speedometer would read quarter speed,
half speed, double speed, etc. - something pretty obvious. If you don’t know what input your speedometer is expect-
ing, try other PPM settings until the speedometer displays a reasonable speed.
Some aftermarket speedometers are programmable. For those speedometers, this setting may not be critical.
ADJUST SPEEDO:
This setting can be used to fine tune the TCU’s speed reading. It compensates for errors in
the entered tire size and rear axle gear ratio.
(NOTE: If an external speedometer - as opposed to the MPH display on the Shift Plus 2 handheld - is grossly mis-
calibrated, refer to the SPEEDO PPM setting.)
While the vehicle is being driven, the screen will display the TCU’s current speed reading. Using the arrow keys, the
speed reading can be adjusted up or down. Once satisfied that the displayed speed is accurate, use the DONE
button to lock in the adjustment.
Since the point of this adjustment is to verify the speed as reported by the TCU, you will need an independent speed
reference for comparison. For example, you could…
- pace yourself against another car being driven at a known speed
- use a GPS unit that displays ground speed
- drive the car on a chassis dyno
TPS CALIBRATE:
The throttle position sensor is calibrated in the Setup Wizard. This lets you repeat that
process by itself. Just like in the Setup Wizard, you will be asked to leave the throttle at the idle / closed position.
Once that value is captured, you’ll be asked to hold the throttle wide open.
NOTE: The full throttle procedure is meant to be performed with the engine NOT running!
TIRE SIZE:
Rear wheel tire diameter can be adjusted or re-calculated here.
DIFF GEAR:
Rear axle gear ratio can be adjusted here.
