I found a book called "How to Tune and Modify Bosch Fuel Injection" written by Ben Watson, published by MBI Publishing Company, ISBN number 0-87938-570-7 price $19.95 USD. The book contains information on several Bosch systems including two chapters on K-Jetronic and K-Jetronic with Lambda. It is very well written and has lots of illustrations and clever trouble shooting tips. I highly recommend this book for all DeLorean owners who work on their own cars.
