Re: EGR Queation...
Because I'm considering eliminating the ECM, but I still want to retain the basic emission controls (cat, air injection, EGR, vapor recovery)...

Re: EGR Queation...
EGR showed up on GM cars around 1973; computer controls around 1980. So you should be able to run the EGR system without the ECM.
Finding the hardware to do a retrofit might be a challenge.

How did the EGR on the Canadian cars function? With just vacuum and a TVS?
I think I answered my own question...
