Setup Wizard
The EZ-TCU™ Setup Wizard will walk you through the initial TCU setup. Once you select SETUP
WIZARD from the main menu, you will be asked...
•
START A NEW TUNE?
YES
will let you continue the Setup Wizard. It will also
reset most settings in the Advanced Options menu.
NO
will take you back to the main
menu.
•
TRANSMISSION MODEL.
Select the transmission type.
•
NUMBER OF CYLINDERS.
Enter the number of cylinders your engine has.
•
TIRE DIAMETER.
If you know the rear wheel tire diameter, select
ENTER
DIAMETER
and enter the value when prompted. Or select
USE TIRE SIZE
to use
the tire size calculator. It will prompt you to enter the tire section width, aspect ratio
and wheel size that is molded into the sidewall of the tire. The tire diameter will be
calculated and displayed for you to review before continuing.
•
SPEEDO OUTPUT.
Different speedometers require different numbers of pulses per
mile (PPM). Select the appropriate PPM setting.
If an optional TCI® Speedometer Control Unit (SCU) will be used to drive a
mechanical speedometer, select “4000PPM OR SCU”.
If you won’t be using the EZ-TCU™’s speedometer output, it doesn’t matter what
setting is selected.
If you will be using the EZ-TCU™’s speedometer output but you don’t know what
PPM your speedometer requires, select the “4000PPM OR SCU” option. Later while
driving, this setting can be adjusted with the SPEEDO PPM setting in the Advanced
Options menu.
Some aftermarket speedometers are programmable. For those speedometers, this
setting may not be critical.
•
REAR AXLE GEAR RATIO.
Enter the gear ratio. This is an important setting. If
you aren’t sure of the exact ratio, enter your best guess for now. Later, you should use
the ADJUST SPEEDO setting in the Advanced Options menu to dial in the TCU’s
speed reading.
•
MAX SHIFT RPM.
Enter the highest RPM you want your engine to reach during
wide open throttle shifting.
•
TPS CALIBRATION SCREENS.
The throttle position sensor (TPS) sends a voltage
to the TCU that varies with throttle movement. The TCU needs to know what voltage
corresponds to closed and full throttle. You will be asked to leave the throttle at the idle
