Hi I have read C663CM3 ( st 93c66 ) from Ori broken BSI,, but dump looks strange like it's corrupted or previously edited by someone else, customer says car start with this ori bsi, I dont see any VIN numbers or Pin in dump or other information like as mileage , car is by year 1999 , please check my dump ! I wanted to clone ori bsi to donor but i don't trust this dump is OK, car is far a way, what can I do in the case if dump is corrupted, need to telecode after Virgin programming ? or just need virgin file and set mileage to "0 km " ?

I tried to read first 93c66 on board with CarProg SOIC8 clamp ( without succes ) , after that desoldered and readed by TL866,, and again by Xprog
dump is in attachment

Thank you Rafal ,
can someone check my ori file please ! I found on other forums 2 file's , these file looks like my file ( without vin and pin ), I am now doubting if my file is really damaged , customers says also car start now with this dump.. if it is corrupt can someone share an Virgin file please ? and how can I find ori pincode , where is it stored more ( in ECU ) ?
