No idea, try to disable mods 1 by 1 to find the culprit. I still don't rule out the possibility of my mod having an issue but since release it got thousands of downloads already and no other person had such a problem.
Hello again! I have one more idea for your mod. High-rev ttsport gauges with redline at 8500. I hope you'll be able to do this also combine your mod with ETK 800 coupe mod, and then I'll finally build a replica of the BMW M3 E92 in beamng. Thank you for the work you've done. I hope everything goes well for you with the mod development from now on. Good luck, Comrade! (Sorry for my english, i know, it isn't perfect)
I'm glad you're enjoying the mods, but by idea for my mod you probably mean your wish , such specific thing is not planned and this would be custom work. For the next update if @Bekwennn:) is available we will try to add support for my interior in the coupe.
You can try to clear ETK 800 cache, disable all mods except mine and see if it's the problem. If issue still persists try to verify game files through Steam.
