Once you have created your calibration, you can save the file to your hard 

drive or an external storage device. To save, click the 

Save

 

 button on the 

toolbar. Then, browse to the location where you want it saved and click 

Save

Use “Save As” under the FILE menu to leave the original file unchanged and 
create a new version. Type the desired filename and click 

Save

. Files are 

saved with a .btc extension. 
To  load  a  calibration  file,  click  the 

Open 

 

button  on  the  toolbar.  Then, 

browse to the file and click

Writing a Calibration to the Torc Module

 

For  the  changes  you've  made  to  take  effect  on  the  Torc  Module,  you  first 
must write the calibration to the unit. Connect the module to your computer 
using a standard USB cord (Type A to Type B). Click the 

Write Calibration 

 

button on the toolbar to write the calibration to the controller. The  Torc 

Module can now be disconnected from the computer. When the Torc Module 

unit is disconnected from the computer, the 

Write Calibration 

 

button will 

be grayed out. 

 
 

IMPORTANT INFORMATION

 

 
How to Avoid Errors

 

The  Shiftware  software  gives  you  complete  freedom  and  flexibility  to 
customize your shifting calibration however you want. This freedom requires 
diligence to avoid errors. 
 
It is 

very 

important that the up-shift and down-shift curves for a given gear 

do not cross. The up-shift point at any throttle position should usually be at 
least 15% greater than the down-shift point. For instance, if the 2-3 up-shift 
point at ½-throttle is 45MPH, then the 3-2 down-shift point should usually be 
less than 40MPH. 
 
The  “On-Off”  differential  between  up-shift  and  down-shift  points  is  called 
Deadband (also known as Hysteresis). The more deadband you use for your 
shift points, the more stable the system will be. Not using enough deadband 
can result in erratic shift behavior. Too much deadband will result in sluggish 
behavior due to a reluctance to down-shift. 
 
Pay close attention to the interaction between different shifts. Overlapping 
the  1-2  and  2-3  shifts  can  cause  skipped  gears  and  other  drivability 
problems.
