Line Pressure Scale –Chooses whether the MAP (Manifold Air Pressure) sensor or TPS (Throttle Position Sensor) is used for the line
pressure table. Naturally aspirated engines should use TPS and boosted engines typically use MAP, as engines can generate boost
under non-WOT TPS conditions which require higher line pressure. The base Wizard calibrations are set to use TPS. If you’re engine
is boosted you should highly consider changing this and tuning so that you have maximum line pressure (0% duty cycle) at by at least
100 kPa/0 PSI of boost as a base recommendation.
Torque Converter Lockup Scale - Chooses whether the MAP (Manifold Air Pressure) sensor or TPS (Throttle Position Sensor) is used
for the torque converter lockup table. Naturally aspirated engines should use TPS and boosted engines can use either depending on
the preference of the tuner. The base Wizard calibrations are set to use TPS.

Up/Down Shift Tables
These tables are used to command the up and down shifts between each gear. Figure 16 gives the low/high range of each gear.
Select each one separately to edit the up and downshifts for each gear. Figure 17 is the graphical editing screen. The Y axis (up and
down) is based on vehicle speed. The X axis (right to left) is based on TPS (throttle position). One gear change at a time is graphed
and can be edited. The red line is the up-shift line. The blue line is the down-shift line. The down-shift line should ALWAYS be below
the up-shift line. The touch screen display is programmed to not allow for a downshift to be above an upshift in each gear (it always
forces a 2 MPH spread, minimum and will give the user a warning if this occurs). Only one item (upshift or downshift per gear) is
editable on each selection.
There should be enough “space” horizontally (left to right) between the up-shift and down-shift lines such that the transmission does not
shift back and forth between gears when the TPS or MAP values change at the same speed. This occurs when you depress the pedal
and the car isn’t accelerating at a fast rate.
Figure 16 Figure 17 Figure 18
Figure 18 is opened by selecting the “Options” tab on Figure 17. The “Increase” and “Decrease” allows a single upshift or downshift
line to be moved up or down by a percentage. This is the easiest way to change a curve. The “Entire Curve” and “Point-by-point”
changes whether the curve is changed by an individual point or the entire curve moved. The Digitally and Graphically selection are
choices on how the graph is edited. Digitally is usually easiest.
Using a stylus/pointer, is the easiest way to edit.
Tuning the up/down shift tables dramatically affects the “feel” of how the transmission operates. Many times this is up to the preference
of the user. Raise or lower the shift points until they suit individual tastes.
You also never want a lower gear up shift or down shift point to occur at a higher vehicle speed than a higher gear shift point. So, scroll
through every table to make sure this is the case at each TPS/MAP point.
Up/Down Shift Calibration DON’TS:
Never allow for a downshift point to be at a higher vehicle speed than the up shift point (the user will be prompted with a
warning and this will not be allowed if this is attempted)
