..true with HEXPROG you can easily read ISN on MSV80 and write to CAS3+ (0L15Y) _ today i just got an MSV80 matched to CAS3 (0L10Y) and for this chipset there isnt a CAS editor for it in HEXPROG. CAS appears to be (2 BYTE ISN) and MSV80 is (16 BYTE SK) this is something i have never seen, car is BMW E92 🤔 im used to see MSV80 mated to CAS3+ not CAS3
