hi this ecu uses 16bit isn that must be the same in cas eeprom and ecu  no sync needed if you replaced ecu align write isn on bench or on car with autohex  or read cas  and ecu on bench somebody can help you too align isn write back too units car should start  if theres no other problems

hi

yes not need sync becuase has cas4 system. ecu and cas are ogininal.. i think problem is that ecu has 5v chip broken and looking datasheet this chip manage also ignition kl15 and has diagnostic line inside
