Friends, I greet all the members of the forum! Please help ! What expression calf and fed mean? The ECU description of the picture. This is a play on words or technical reduction? How important are the differences?

californa has stricter emissions standard than the rest of the country so there is cal= 50 state emission compliant and fed=49 state emission compliant and is not authorized for sale in cal. as far as the ecu i'm not sure exactly what the differences are.

Differences are minor from 91-92. 93-94 are similar to themselves but very different from the early versions. Wiring harnesses are different, pin usage at ECM is different etc.

I would reference the part number of your ECM, if you are looking to get another one.
