Is there expected ETA to v3 firmware release on classic?
MAP filter filters alway analog input channel assigned to MAP.
In your case if filters the Analog input 4. Could you please publish log with RPM drops ? I can take a look.
I’m working on this right now. I hope the beta will be availble at the beginning of Q2/2026
Its possible in the next time to reduce torque via DBW in Traction Control System?
The log is here.
map_filter_4ms.BG3 (714.5 KB)
map_filter_8ms.BG3 (884.5 KB)
This does not happen if you set the filter to 8ms or 16ms.
Also, I’m not sure if this is related, but when this occurs, the display on the Realdash side via CAN also momentarily becomes abnormal.
From our experience it doesnt work well as there is a huge lag between slip and torque reduction by controlling air.
I think the issue could be with the more pressure variance with 4ms.
Also there is different idle target in both log.
But what I saw is too much variation in air % PID. Try to lowev the PID coeeficient for example by 10, and then check the idle if it helps.
Anyone manage to make dyno feature work in V3?
The difference in the idle target is due to the fact that the logs were taken after a cold start, which can see by looking at the CLT.
Next, regarding the air % PID adjustment, it responds after the RPM drops. No oscillation is observed.
Looking at the points where the RPM drops, the MAP rate changes significantly.
Does that mean that with a large camshaft duration, setting a small MAP filter value will pick up the fluctuations and may compromise RPM stability?
Yes.
If you look at the Airflow PID % fluctuation it is much to fast for the engine to react. Even if it is not a cause of the RPM drops it is not ok.

I am a “noob” tuner and absolutely MUST have a working base tune to start with since importing my working V2 file was zero help. Also having 0 mean 100 is confusing - does that mean if I want something at 80 I need to set it to -20? Why not just use “normal” logic???
The corrections are 0 based. So if your correction is 0%, there is no correction (in V2 the tables had 100% as no correction).
For example Fuel correction in V3 (no correction)
The same table in V2
If you use Import function the importer will convert correction tables where required.
Can we add it to come on after timing isn’t enough? Like if all four wheels are spinnig based off GPS and we pull max timing but still have slip, it cuts throttle. Like EMU Pro
Can youadd a 3D option for the armed state to control the rpm change rate?
Whatever I do, I cannot fix the random stalling problem. If I adjust the values high, the engine revs over up idle or does not go into the idle state. If I set the values low, not always but dropping from high RPMs like 5k, and during slow gear changes the engine stalls.
During cranking, before reaching the target oil pressure, the coils fire. Can the same logic be applied to the “Disable Spark When Start Delay” option as well?

- What Y axes do you mean for Armed state airflow table ?
- Just to make sure. Do you want to disable fuel and spark until oil pressure reach the defined value ?
These are some UI improvements I have thought of that I think would be nice to have in the client software.
Possibility to reorder the desktops / tabs
It would be useful to be able to reorder the desktop tabs to organize the projects by drag drop, right click menu with option to move left/right or some other way.
Possibility to scroll the desktops / tabs list with the mouse wheel
If the client window not is maximized or the help section is expanded not all desktops / tabs are visible. It would be useful to be able to scroll the desktops names list bar to access all the desktops / tabs and then select one by clicking (similar to how the sheets names tabs bar is working in spreadsheet software).
Possibility to add and remove arbitrary number of desktops
It would be useful to be able to add more desktops if needed and also to remove empty desktops if not needed.
Windows position and resizing snapping
It would help with building screens if both the windows position and resizing could snap to adjacents windows and desktop borders. This would make alignment easier. There was some snap setting for the windows top left position but I cant find it now?
Something like this.
Or some suitable sized (invisible) grid if enabled in the settings that window position and resizing snaps to.
Copy/paste map data outside of the client sw
It would be useful to be able to copy and paste map data outside the client program, for example to copy a map to or from a spreadsheet. This can be useful when creating base maps by formatting/resizing stock maps in a spreadsheet and then pasting them into the EMU Black client sw.
Now it seems to work to copy from client to spreadsheet, but not the other way around from spreadsheet into EMU Black client sw.

Thanks for answer
- Y axis would help when rpm is dropping rapidly, we can enter higher values for the armed state so the engine recovers from stalling. Slower RPM dropping requires lower armed state values so it doesn’t overshoot the desired idle value..
2.Yes
sorry for any inconvenience, English isn’t my first language.

Thank you for the suggestions!
All of them are added to the bugtracker. Now I’m working on modifying Windows client to work with Black and Classic V3 firmware.
However we try to implement some feauters (like paste from excle, or grid) in the meantime.

You are right. There should be such option but it disapears from the general settings.
It will be restored in the next version.
For now you can edit config.xml and change windowsSnap from 0 to 1.
