New Release of CTW Probe Software

CTW is happy to announce the release of its latest version of CTW Probe software. While it has taken an extended period of time, this new version was a major undertaking to make sure we had a platform to move forward in the best manner. We will be moving forward using more frequent releases to develop and fully expand this software suite into the dominant player in the testing industry.

Look for videos to be released on our YouTube channel to help our customers get the most out of the software.

This version applies to anyone using a CTW Automation damper dynamometer and certain Roehrig crank dynos.

Be sure your machine is ready.

A. You must first have updated to CTW Probe version 1285 before moving forward
a. Send an e-mail to so we can get you first to 1285.
b. Call 336-542-5252 as an option

B. You should back up your settings first: File / Backup settings…..

C. Save a copy of your Test folder.

D. If you are using the Spring Rater program, do not update until notified

E. If you are not using a VFS15 motor controller, do not update until notified. This would apply to several Roehrig machines that have switched to CTW Probe but are still using older controllers like the VFS9/11

F. If you are using a LA – Linear Actuator or a Roehrig EMA please call/e-mail so we can ensure all proper items are added.

  2. Tree in “Test Data” tab that keeps all PVP runs grouped with the PVP composite graph.
    a. You can also group by any category listed in the fields
    b. You can sort by test speeds, frequency or any field listed
  3. Live data performance improved, runs longer.
    a. Live data does not require as much memory which led to issues with the software and computer
