Or do a search for 1993 Camry V6 ECUs which are still working OK... I can verify a 1995 Camry 3VZ-FE ECM works in a 92 Lexus ES300, but the gear changes are ever so slightly lazier.
It's been a while. And I finally got some good news and some bad news too...
So I was able to solve my problem - picked up an ECM from a 93 3VZFE from a local junkyard, and upgraded it with Japanese capacitors.
It looks like previously I had bad luck finding an ECM that would still be salvageable and that's why I was having a hard time figuring out the problem.
Then I was only able to enjoy my car for less than a week and on my way back from work I noticed white smoke coming out of exhaust.
Checked oil and coolant and it was obvious that I had a blown head gasket on bank 1.
Anyway, this concludes that.
By the way, if anyone's interested in practicing their soldering skills - DM me here, I can send you my ECM and/or AFM for the cost of shipping if you're located in Canada/US. Or we can meet in person in Vancouver, BC / Seattle, WA.
There's a good chance this AFM can be saved - I was gentle when I pulled out the harness.
Plus I will include capacitors from Digikey with an ECM.
Just don't want to throw all of this in the trash.

Ain't that splendid..
What's the plan for the car if you don't mind me asking, it's a pretty well known problem for those, should be relatively easy to fix if a bit expensive, seems like there's still life left in that car after all..

Depending on your plans for the car, the ECU may still be salvageable, and may be worth getting shipped out to a place like Tanin Auto for a for a rebuild as a spare unit, said place runs diagnostics on the ECU and tests it on an actual car before shipping them back, assuming they have this generation ES.
Well that's a bummer, sad to see another ES succumbed to a head gasket. Either way, thanks for getting back, at least one of the issues got resolved..
(Edit - Just realized the IACV question is now moot with the blown head gasket. Bummer. Never mind).
FWIW, I just CLEANED (rather than replace) my likely original IACV in my `98 3ES. It had been gunked up and stuck in an open position (a fixed orifice?) for years. Once cleaned, my car's ECU got confused and things got really rough around idle speeds.
Unplugging the battery long enough to reset the ECU got things right again.
What does this mean for your '92? I don't know. But unless your ECU is functional, an OEM IACV (Aisin is likely the closest you'll find new - they're a key Japanese OEM supplier to Toyota) will never be put to proper use.

I did my math and the best course of action would be to eat the cost and sell it to a mechanically inclined person who could fix it and use it.
At the end of the day, I'm paying for the head gasket problem either way - by selling it with a huge discount or by fixing it myself.
And since I got two other cars that are special to me, I just don't want to spread my resources too thin.
