Hi,
I try to understand how to immo is calculated in FBS3 system.
When we read FBS3 data from unit, we have 8 poles for keys, service, etc. We can calculate unlock key (for virgin).
Does unlock key and immo key are different?
I know ID's for immo "ask", "reply" 101/111.
ID111 reply always with 8byte hash and 2nd reply is (probably) 4byte distance?
1st reply message always 3 bytes are constant data)
2nd reply 1st bute is constant data.
I recorded many ignition-on states from one car, but still can't find solution
