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

same issue here while opening previous configurations

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:

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

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.

What could be the reason of this message Blocked: No Lambda Assignment (-17)?

Lambda Assignment is needed so the ECU knows what cyclinders the O2 is used for. Open the ‘old’ file and look at the report for the upgrade. It will tell you what issues you’ll have from the upgrade.

Lovely. Thanks, will try this.

Weird Iqnition overrun issue. Anyone can help what can cause this?
last burnout, overrun cause iqnition angle to 0. Why?

UPDATE

Overrun is disabled, but somehow when we have first time antilag on, overrun state go from 0 to 1, when we disable antilag using button, overrun state go to 2 and be there what ever we do with throttle. Again antilag make state 4 and release state to 1 until antilag disabled make it 2 and keep overrun on.

Seems like bug?

I see where overrun is active but could this be a case where you previously had activated overrun and then unchecked enable and forgot to make permanent? The base overrun angle is -5 but your only dropping to 0. Try setting the cut type to fuel and ign and see if it remains active after disabling it.

I am pretty sure it have not been in use, and this exact file was on car.

I will try that if dont hear anything from ecumaster before.

@123cdi we will analyse the problem and get back to you.

@FrogJam_Motorsport Have you identify the problem? Does the new version delete the assignment? Please provide the project from 222 version so we could look at it. Post it here or in PM.

@123cdi we identified the problem. It will be fixed in the upcoming software release.

@123cdi your problem has been fixed in a new version 261.1. Thank you for reporting this.
