Arrow IKM0S Software OTS Maps

Hey, for testing purposes I wanted to change the ROM of my IAN0S based manual 335is to the 1M ROM, the Ikm0s. Now the flashing itself works without any problem. I flashed a slightly modified stock bin from a US 1M via MHD.
HW shows that the car then is powered by ikm0s. Now when I want to flash an OTS Map (2+) it reverts back to Ian0s. Is there any way to fix that? Did I do something wrong?

I own a Super License and tried flashing back to stock (uninstalling MHD) and then flashing the 1m bin with no success. I read something regarding the ZB number somewhere. Is that the correct trail? Do I need a specific Custom tune for the new ROM? My car has a Aftermarket DP and a 7,5 fmic so nothing crazy.

I am new to all that so help would be greatly appreciated.

Strange. Where did you get 1M bin? I haven't had an issue flashing to IKM0S in the past

The latest EU 1M map assuming your in Germany is 8619148.

You will run into errors running the map as is. however i'm sure the checks can be disabled.

I flipped two bits that disabled said errors. Power Index and a second one. I got the 1M bin from another forum post here somewhere. They were both confirmed to be from stock cars.

I also didn't encounter errors when flashing it's just when I want to flash an OTS Map on my "Stock" Ikm0s car that it reverts back to Ian0s.
