My '83 Brat GL EA81 doesn't have an ECM. My '83 GL EA81 wagon doesn't have one either. My '80 EA71 wagon (gen 2) of course doesn't have one. Hatchy's '87 standard EA81 Hatch doesn't have one, nor anything else(very standard). Both '83's have DCP306-21 Hitachi carbs. Are the '83's supposed to have an ECM?

I think the '81 DL EA81 2wd wagon I used to have had one.

The only control module i have seen on stock carbed models is the revolution sensor....this stops the fuel pump from going unless the engine is turning..then it allows the pump to function..it is usually mounted beside the fuse box on the pillar tower behind /above the drivers kick panel..cheers

there is a computer with the feedback carb versions of the EA81s but I dunno what all it intales...

I think the fuel injected model had one also.

Feedback carb's - ah yes.

 

Feedback's (carb with ECU, temp sensor, O2 sensor, vacuum modulated enrichment controls, etc, etc) came on all 82 and up 2WD's, and ALL California models. This includes EA81 and EA82's through 87. They came with either the Carter/Weber single barrel (early EA81), and the Hitachi. They actually get very good mileage, and in the case of the EA81 Hitachi version, are decently easy to repair and troubleshoot. The EA82 version is a total mess, and I never did get the one I had to stop throwing codes. It wanted a part replaced that I was unable to locate a good used replacement for, and the dealer wanted my first born for it. I deemed it disposable, and threw on a Weber.
