The E21 used Bosch K Jettronic. K = Kontinuous (Gotta love German spelling). It does not have a cps as the fuel flows (k)continuously. The spark is produced by a conventional distributor but usually with electronic 'points'. The manual for the fuel system I found for free on the web and it was very helpful. I guess you will end up with a fuel problem of some type. Check out the manual first to get some idea of how the system hangs together. Give it a good conventional tune up first in any case.
