  • Page 3: Main Menu

    INTRODUCTION The built-in Quick 4 User Interface allows most sensor values to be viewed, while also allowing the transmission to be manually shifted. With firmware version 3.0 or later, self-contained, basic tuning of transmission settings is also possible via the tuning menu.
  • Page 4 SEL = Manual Select In status mode, double-clicking the function knob will activate or deactivate manual selection mode. SEL will be displayed for 2.5 seconds, then return to the normal status screen. Like Manutronic mode, this mode enables manual gear selection and includes safety features to prevent inappropriate downshifts.
  • Page 5 Select mode is the power-on default. You can select tables 1-4 to override the table select input and force the Quick 4 to use a specific table. Once you have selected the desired table or mode, you can exit select mode by pressing the knob once.

  • Page 6: Error Codes

    2.5 second intervals with the current display mode. Error codes will not be shown while in tuning mode. It is a good idea to periodically check the Quick 4 display for errors as you drive, so it is wise to consider an accessible mounting location.
  • Page 7 F:bL The voltage to the controller has dropped below 8 volts. F:bH The voltage to the controller is above 17.2 volts. F:tP The Throttle Position Sensor is in fault mode due to the voltage being below the idle threshold value that was set. F:rS Indicates a fault in the Range Sensor (PRNDL switch or pressure switch module).

  • Page 8: Tuning Menu Options

    This setting is used to adjust the idle TPS (throttle position sensor) voltage threshold. This setting is important as it allows Quick 4 to determine where the idle position is and to prevent false detection of a throttle position sensor failure.
  • Page 9 1:2U = 1-2 Upshift This setting is used to adjust the full-throttle shift RPM for the 1-2 upshift. The RPM value is displayed in thousands (e.g. 5.25 = 5250 RPM). If you are in doubt, start on the low side. Press the knob once to enter the adjustment mode and change this setting.
  • Page 10 1:2F, 2:3F, 3:4F = Shift Firmness of Each Shift Independently adjust the firmness of the corresponding shifts at light throttle. Value is expressed in commanded line pressure (PSI). Higher values provide firmer shifts. This value should not be adjusted until after the shift points are set since the light throttle shift points have a significant effect on shift feel.
