Automatic conversion to a newer version (261.X) of the project does not work.

same issue here while opening previous configurations [image]

We have removed the beta version due to a bug affecting offline use without an ECU connection. An updated version will be released on Monday.

Those basemaps (camaro, corvette and mini) includes OEM CAN BUS Integration?

Yes. You can see what’s implemented on the specific websites for each base map: [image] Ecumaster Complete Range of Electronics for Motorsport Edit: The website is not yet fully updated (it will be updated when the non-beta version is released). You can also check the base map description in the client software with the base map loader tool.

@allihov @norbert.parkita Thank you for testing the software. We have released an updated version, 261.0.1, which fixes the issue you reported. As before, you can download it from: https://www.ecumaster.com/testVersions.html

I like Basemap selection, wizard style. amazing. Good job guys.

@Jan_Matlag_ECUMASTER One more feature, Is it possible to export only Project Tree? I investigated and couldn’t find that feature.

It is possible already. File / Export part… “Custom” section on the bottom is for project tree.

Hi there, I updated to this firmware from version 222 and the car took ages to start and the short term fuel trim was disabled due to “Blocked: No Lambda Assignment (-17)”. As soon as I went back to firmware 222, no short term trim issues and the engine fired up instantly. Any idea what might be causing this? Have project files and logs if needed.
