Mercedes discontinued CIS-E because of the US emission requirement for sequential control of fuel. The fuel must be turned off on a cylinder that is misfiring to protect the catalyst.

To get an idea why MB was the last to leave CIS one might look to the Porsche Carrera engine. In the car the motor h
as Motronic - One control unit for fuel and ignition. When the same engine was used in a Mooney (sp?)airplane the fuel system from the earlier 911SC CIS was used.
