EKE TO EKR FILE CONVERSION > Q&A

I’m trying to convert EKE TO EKR but I’m confused on which ECU protocol to choose. I have tune files in EKE format that need to be changed to EKR. I see there are a lot of option to pick from. I have the SIEMENS SIM2K-250 Elantra N 2024, there is a “FLEXTUNE, CAN BOOT, MAKE PATCH, OBD,” options. Please let me know which is appropriate to pick from in this situation.

Thank you.
