If you just wont to adapt keys for PSA group PIN can be calculated from eeprom - PIN can be programed to the ECU.
Hi tihiuvek,
So the eeprom contains data that is checked against the flash, so the data in the eeprom is like a checksum for the flash data too?
I'm a little confused about how the PIN is stored and used from single connector to three connector ECU's.
As far as I understood.
Single connector had coding for immo/security data on the eeprom.
Three connector sounds like it has coding for immo/security on the eeprom in an encoded form, which can be decoded to then be able to be written to the flash (if you need to)
So what are the impacts on the BSI? Does the three connector ECU use the flash to check the security code/pin, or the eeprom?
Does this mean if you write a different file to the flash on any PSA three connector ECU then the immobiliser won't work? Ie, you'd need to always edit the original file if remapping?
I assume in this case that the security data pin/code is still on the eeprom for BSI coding...?
Thanks for any clarification you care to share!
Many thanks
Dave
