No prompt, and unable, to save updated BMW EWS3 EEPROM file after Key Learning function. Utilizing MaxiIM IM508 and XP400 Pro. Any assistance is appreciated. Thank you.
No changes should be made to the eeprom. You shouldn't need to write it back. It should just be a question of reading key data from the eeprom and writing that to the key. I've done many hundreds with AK90 - never once wrote the eeprom back.
