@Reyser yeah finally i found the problem and already fixed it.
do you know which line that affects dials to work ? some says, you have to edit <dashboardtype> in vehicles.meta?
i tried to change it in my own addon cars pack but some cars works and the rest don't

@Reyser
i try to make add-on packs by put aige's huayra and p1 into 1 addon dlc.
but the problem is tuning parts disappear when i pick it in LSCustom / trainer.
modkit ID works fine, because tuning parts showed up in LSCustom /trainer, but when i apply it, It's disappearing car's body.

i copied exact carcols and carvariaton lines from both dlc into my own carcols and carvariation.

any idea what's wrong with my problem ?
