This is flash readed from secound ECU. But it was overwritten. Does it work when i get back to this ori file or maybe Yours is better?

Is this possible that with wrong ENGINE MAP there was no comunication by OBD with ECU? In 29F400 slash is ENGINE MAP and in 25128 is data about ECU (data immo etc.).....?

Doesn't worked :beheaded:

The Question is - if I will buy new (used) ECU - do I have to unarmed cover and recopy EEPROM 93C56A or Can I adjust immo by DIAGBOX without any problems? I will need ACCESS CODE to done it - Am I right?

yes...wirgin ecu....virgin bsi...what type of bsi do you have?
can you read eeprom from your new ecu?
can you find pincode from the dump of eeprom ecu?
now,you know the pincode for that new ecu
so,
virgin eeprom from bsi....all eeprom FFFFFFFFFFFFF
and recode with diagbox from start to the end
and
carrefull...select the real gearbox (automatic or manual)
if is wrong selected,nothing will work on your dashboard

I have rewrite eeprom 93C56 as I always do and Car works fine. This ECU I don't want to touch. Now I want to write 29F400BB in another ECU and if it works I will CHIP it.
