You need some hex editor and find all 33 values.
You need to find in hex all 33 values and replace them to 60 in hex. Its better that you use content from your chip cause, coding info are in this eeprom and some other. I will show next with one file what i got. You need to desolder it and read content. In other side of cpu and eeprom chips find small 8 pin chip B58253. If you are not sure – ask in comments.įirst what you need are programmer that can read 24c02 chip. 074 906 021 (in aluminium casing only 1.9, 2.5)īasically all ecus will work if they are similar to ones above.
I assume in this case that the security data pin/code is still on the eeprom for BSI coding.In this guide i will show how to remove immo from VAG MSA15 ecu. 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?ĭoes 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? 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) Single connector had coding for immo/security data on the eeprom. I'm a little confused about how the PIN is stored and used from single connector to three connector ECU's. 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? If you just wont to adapt keys for PSA group PIN can be calculated from eeprom - PIN can be programed to the ECU.
