Bosch K-Jetronic CIS fuel tuning procedure

The Porsche 928 continuous injection system is very robust when properly set up.  However, it requires clean fuel and pressures set to the correct specifications. 

This 6 page procedure is designed to guide you through setting a baseline fuel tune on your early 928 with Bosch K-Jetronic CIS. 

Primary focus is to help you get a non-running 928 to start and idle again, especially when it has sat for a long time.  Also, it may be useful to set a new baseline after extensive engine service has been performed on your 928.
