I doubt you're dealing with a PI controller.  It's probably a 
bang-bang controller.  The feedback from the exhaust gas sensor
is almost binary.

There's a 25 page chapter on KE-Jetronic in Bosch's Automotive
Electrics/Electronics Systems book (ISBN 1-560 91-596-X).  You 
can get a copy through SAE (400 Commonwealth Dr., Warrendale,
PA, 15096-001  USA).  I think it costs around US$35.
