SETTING UP THE QUICK 4
Step 6: Calibration
Verify that the correct calibration is loaded
on the Quick 4. A standard calibration
specific to your order is loaded before
shipment. However, if the transmission
configuration has changed since the order
was placed, you'll need to connect the
Quick 4 to a Windows PC and install the
Shiftware Tuning Software, which can be
obtained from our website (under Support -
Shiftware) or the included CD. Using the
software, load the calibration that matches
your transmission's configuration.
Step 7: Throttle Position Sensor Calibration
Whether you have electronic fuel injection or a carburetor, you will need to set
the throttle position. To do this, use the throttle position calibration option on the
built-in tuning interface. Turn the knob until “Setup Menu” is highlighted. Click
the knob to enter the menu. The first item that will be highlighted is “TPS Setup”.
Click the knob to enter the TPS screen. It will show the current idle and WOT
voltage values as well as the current throttle position sensor voltage. Press the
knob again to enter the TPS setup menu.
To calibrate throttle position, the ignition should be on but the engine not
running. For carbureted engines, make sure the choke is fully open and off the
fast idle cam before beginning. In the TPS setup menu, highlight “AutoSet TPS”
and click the knob. It will begin detecting the idle throttle position right away, so
leave the pedal untouched.
Next, the display will show “Press Accel Pedal”. Push the accelerator pedal all
the way to the floor and hold it. After a few seconds, “Release Accl Pedal” will be
displayed and you can release the pedal. If no errors occur, “AutoSet Success!”
will display and the values will be shown to the left. If an error occurs during
calibration, the display will show the error and abort calibration. If this happens,
you can try running the calibration again. If errors continue, you may need to
check your wiring for problems.
