3 PROM ID chips in car, how to tell which is which?

[323GTX]

There are 3 PROM ID chips with this car, one in the computer obviously and 2 in the console.

How can I tell which one is which? They are not labeled or clearly identified.

Maybe I can take a close up macro picture and post it.

Without being labeled the only thing that can be done is to read them. Basically need a PROM burner to read the contents. Then compare each to a stock calibration.

Note the changes between the stock cal and the PROMs you have.

This can be tedious, depends upon how many changes and what type of changes have been made to them.

OTOH, it may be that the changes are minor and the differences may be seen quickly and easily.

Thanks for the reply, I guess that's the only way.

Nothing is easy!
