Do you know how to make the ecu for manual transmission?
Or it’s impossible?

Last time I only write eeprom from old to new ecu and don’t need change any coding
may old automatic and new manual and don’t possibility drive if I write only isn
I copy full eeprom and write full eeprom to new

 

Question:

Wich tool you read and write?
My old ecu water damaged can’t connect with it

 

Answer:

I have x17 and flex and used for read.

 

Or try Aultel (like Autel MaxiSys MS908P or Autel Maxisys Elite) and coding ECU should fix it . Also if you have Online access with Autel , do software update after Coding.

Or try BMW ICOM to do it, BTW, ICOM NEXT is cheaper than AUTEL

Google and you’ll find some videos or articles on how to use Autel for BMW coding.

 

Enjoy!
