US Shift 4R70W Installation And Operation Manual page 31

If Select Pairs Together is enabled, then the corresponding down-shift point will
be automatically selected along with the up-shift point. This can be turned off by
clicking the Select Pairs Together checkbox on the right. You
can select multiple points by holding CTRL while clicking the points or a range of
points by holding SHIFT and clicking the two points on each end. You can move
between adjacent points using the LEFT and RIGHT arrow keys.
Once a point (or points) is selected, you can drag it with the mouse to raise and
lower its value. A yellow box will appear in the graph telling you what the value
of the point is.
Adaptive Learning:
By default, the Quick 4 will learn the shift and TCC timing characteristics of your
transmission. It will complete a learning cycle over the first few hard-throttle
passes and will use the learned data to optimize shifts. For learning to occur, the
tachometer input signal must be connected and functioning properly. During the
learning cycle, you may notice unusual TCC operation. This is normal and will
end once learning is complete. Once learned, the data will not change unless it
is erased using the clear (CLr) command on the controller's display. Clearing the
data will cause another learning cycle to begin.
For optimum accuracy, learning should be done at the same transmission fluid
temperature that it will be run at during normal operation. Once learned, shift
point accuracy will only be limited by the consistency of your transmission's
valve body.
If you wish to disable learning, enter Settings in the tuning software and switch
to the Miscellaneous tab. Uncheck Enable Learned Shift Timing
. This will stop the controller from using learned data,
but will not erase the learned data. This would be useful if you plan to make
changes to the transmission or are unable to complete a proper learning cycle.
