By "Flash" you mean what eprom/flash memory chip is in a certain ECU ?
If so, you can go to:
- http://www.alientech.to/drivers/autobbs_login.asp -> enter the word: demo in both fields and then you just have to select the Brand and Model of the car, you can even search by ECU number, and you get the info about the eprom/flash in each ecu.
The same applies to this site:
- http://www.dimsport.it -> choose Italian flag, then go to "AREA RISERVATA", another window opens and then goes directly to the login, you just need to enter the word: "guest" in each field and it's quite similar to alientech site, maybe smaller database, but very good.
Hope this helps.
Also, there is a sticky thread somewhere on here with files attached to it, that contains that kind of information.

P.S: That section should be called: "ECU & OBD Locations"
