I am the owner of a 2000 vw beetle (APH). i am looking for info on my ecu. correct me if i am wrong but i beleive it is a motronics Me7.1   06A 906 032C with an eprom memory, narrow band o2 . anything would be great, pinouts, schematics, links to more info, tips for modifying i am just trying to learn as much as i can about this particular unit before i do anything with it. I would prefer to keep this unit  rather than swapping out for the wide band ecu but if that is the best rout i already have the wiring harness for a wide band. So tips on this swap and issues you find would be helpful as well. but like i said anything would be great!
thanks!
