Hi 914 club, I am a new member to the club but a long time owner (since 1989),
Any how, I am looking to identify the make of my ECU, I know it is as simple as looking at the sticker on top of the ECU, however at some point the ECU I am currently using was spray painted and then the paint was scratched away to reveal the sticker (not by me) and when the paint was scratched away the numbers from the sticker were also removed, and I can not make out the last few critical numbers.

So my big question is how in the world can I tell what ECU I have? Is there any internal markings that may lead me to my answer?

What I do know, is that it is D-jet, it has a idle mixture knob and I am running it on a 2.0. My throttle body is a '74, but my head temp is a '73 w/o a ballast (and yes I am having some issues).

Thanks in advance,
-Rob

Some (not all) ECU's have a sticker inside. See the second ECU pic here for an example:

I did all my inductance characterizations using an LCR55. Because of variations in the inductance measurement methods of various meters, I cannot guarantee that the calibrations will be valid if you use a different LCR meter (e.g. different small-signal drive current, detection circuit, etc.).

Best way to set up your 2.0 is as a '74, as far as the FI components go. Get rid of the ballast resistor, get a 012 or a 003 CHT, a 043 MPS, and a 043 or 044 ECU. You can also get Jeff Bowlsby to recalibrate a good MPS to 043 specs. In a pinch, you can use a 037 ECU on a 2.0L '74 setup without problem.
