CIS was used on '76 and later V8s, including the M-100 (450SEL 6.9). Cars pre-'76 suffer from vapor lock problems. Not fun to deal with and a major pain in the butt! This injection on the early cars was known as D-Jetronic, and on '76 and later was K-Jet. And in 1980, the final year, came K-Jet with Lambda. Finally, the continuous injection systems (CIS) were as follows: K-Jet, K-Jet with Lambda, KE-Jet, and KE-Motronic. So Justin, I believe you are wrong in your thinking. Hope I have clarified this.
