If Baris can't help i have a full cic setup for sale here https://forums.m3cutters.co.uk/threads/cic-retrofit-for-e9x-including-combox.233891/#post-3113758 Happy to answer any questions you may have regarding the upgrade.
I don't think Baris receives alerts for this forum but he always picks up the phone. Spoken to him a couple times to get some info and he was very helpful and knowledgeable (that was regarding E6x/E9x platform stuff aswell)
