New EMU PRO software version 261.2-RC1 is now available.

This update adds a couple of small client features and fixes several minor issues.

New features:

- Added menu command: Devices / Disconnect
- Added a “Save DBC File…” button to the Project Tree / CANbus Transmit Frame

Fixes:

- Fixed EMU PRO-8 compatibility with EGTtoCAN – all 8 channels now work correctly
- Fixed a rare bug causing VE Tuner to show large negative numbers in the Proposed VE table
- Fixed an issue where the Vehicle / Speed Limiter / Activation Custom Channel was not working correctly
- Fixed a bug that prevented saving a password-protected project in offline mode (issue introduced in version 261.0)
- Fixed an issue where the frequency of the “Engine Cylinders cut” channel was not loaded from a project file

This is a release candidate — if no major issues are found, it will be promoted to a public release. We’d appreciate it if you could give it a try and let us know if you run into anything.

Sincerely,  
The Ecumaster Team

Thank you for testing the software.

I was able to reproduce the issue. The menu under **Airflow Enable** disappears completely.

For now, the workaround is to refresh the UI using the **Shift+Ctrl+B** keyboard shortcut (menu Devices/Reconnect).

We will do our best to release an update tomorrow.
