What does this all mean?

Depending on the year and whether you're a turbo or not, you can probably swap ECUs with another car and not have issues. It is very common for people to use automatic ECUs in their manual transmission cars. It has been reported, however, that people who use manual transmission ECUs in their automatics have difficulty with keeping the car idling. You should be able to swap Federal into California models, but a California ECU in a Federal car may throw a code.
