We all need to watch our use of jargon here. CMA stands for Check Measure Adjust, a Porsche Factory booklet 4532.20. It is titled “Porsche Mechanical Fuel Injection, Check, Measure, Adjust.” This is the “bible” we all use. It isn’t complete and is designed for knowledgeable technicians and all new components. I’m working on CMA2 – an extended version – that is understandable by novices, is far more detailed and deals with geriatric MFI.

Here is CMA in pdf format.

The critical issue with MFI (as with many other systems) is to confirm the proper operation of all the engine systems before you adjust anything.


Best,
Grady
