CIS (Continuous Injection System) is the generic description, the specfic type is Bosch K-Jetronic, so they are sort of interchangeable terms (although there have been other brands of CIS not used on Saab, such as the early 60s Rochester Products stuff). K-Jetronic comes in 2 basic flavors: non-Lambda (open loop) without Oxygen Sensor (also called Lambda sensor by Bosch) feedback control which was used on 1975-1980 Saab 99s and 1979 900 non-Turbo cars, and "with Lambda" which has the O2/Lambda control (so adds the Oxygen/Lambda sensor, the modulating valve, and the control module) which was used on 1977 California 99s, 1978 - 1980 California/High Altitude cars, and all Turbos 99/900 and all 1980-1984 900s (and 1985-1987 8-valve non-turbo 900s). K-Jetronic was also used extensively on VW, Porsche, Audi, Mercedes, Renault, Volvo, Ferrari, DeLorean, etc. through the late '70s and early '80s. I'm not sure about BMW. Hence, there is a lot of parts/rebuilding/support for it outside just the Saab commmunity, which is a good thing for us!
