Upgrading Motronic

[Kevin Krooss]

Hello, I'm new to the list. Glad I found it.

I have a possibly foolish newbie type of question.

Would there be any advantage (and is it possible) for me to upgrade my
Motronic 1.1 to a newer version? Assuming I found one at a reasonable
price in a junk yard somewhere.

I currently have a 0261 200 150 which I understand is a 1.1 in my 1988
BMW 735iL. I'd like to have some of the more advanced trouble codes
available. I understand this unit only has 4 basic codes.

Thank you.
