Yes.  "How to Understand, Service, and Modify Bosch Fuel Injection and
Engine Management" by Charles O. Probst.  It is published by Bentley and
can frequently be found in the automotive section of your local
bookstore.  $30 and well worth it.

If you have Bosch L-Jetronic fuel injection ('75-'83 air-cooled vans)
then you can also go to my web site,
http://www.type2.com/bartnik/tech.htm and check out the FI info there.
