soldering up a Supra AFM
#22
Har har, you know I meant 22R-E AFM.
Anyways, I had some spare time today, so I plugged the 82 Supra AFM onto the RTE. The temp sensor is shot on it, and threw a code, but the vehicle ran and boosted otherwise fine (although really rich. Needs a tension adjustment). The Supra AFM is a 2.5"x2" opening, making it 20% larger than the 22R-E's 2"x2" opening. It also has a 3" pipe inlet, and outlet.
874Runnersr5: I talked to him today, he's looking around for it. If not, I can mod you up a later gen one, or possibly sell you mine when I replace the temp sensor. I have a megasquirt unit ready to install in this truck, so I won't be using the AFM for much longer anyways.
The whole swapping 22R-E electronics into later 5M AFMs is actually pretty common in the Celica world. It's pretty easy if you're handy with small parts, and a soldering iron, it's pretty easy.

Cool, I'm still interested in this swap. I figure if I can't get a hold of the plug-n-play one atleast I can swap guts. I'm pretty good with delicate/small electronics, so I'm not worried.

Great information on testing the wiring harness on a 22RE.

Mentions the reason why the 1982 Toyota Celica Supra Mark2 5GME AFM is different than the other years. It used a 9-to-0 volt output instead of the 0-5 used from ’83 until ‘85.5. If using from 83-85.5 the circuit board will have to be swapped and re-soldered.

Hey Logan! The push bar is almost ready for a full install. Got a new winch and lights wired clean. Just waiting for the bottom brackets, which are getting fabbed to accommodate a future body lift. Pics soon.

So if I read that right, I might not have since electronics confuse me easily, it's saying that the 82 Toyota Celica Supra AFM is a direct swap for the 22re AFM but years other than 82 will have to be modified?

’82 Supra 5MGE AFM #22250-43110
Here's a great thread with comparison pictures, part numbers, and a installed picture with a 180 degree bend, something I want to do to make room for dual batteries.

http://pirate4x4.com/forum/showthread.php?t=594281
I've noticed on many sites the part number listed as #22250-43110 & #197100-3020 (both are printed on top). #22250-43110 is the commonly used number.

Junker, I just noticed you've already done a swap with an '82 from your post on the LC air intake thread. It looks great. Did you get lucky with the year or did you already know '82 was the magical year?
The filter, AFM, and piping look clean, keep it coming.

Thanks for the compliment! I'll be doing the same conversion on my 4runner when it gets here.

I need to know whether its just the connection from the plug to the circuitboard that needs soldering or is there more to the swap?
Good link, this is what i want to do, and install dual batteries as well.

Matt finding one is hard enough, deciding if paying what the seller wants for it for the gains is even worse. I got unlucky in that the first one I found (wrong part number) was only 16$ but consider myself very lucky to have found one that was right for just under 70$. If you can wait for a few days I'll be able to go back to the yard and see if they have any more. Although I can't send you one for free I'll only charge you what they did (I'll send a copy of the vendors reciept along) plus whatever shipping will be.
That is if I can find more than one since I need one for the 4runner.
I'll keep you posted.
edit: I forgot to add that a new one from NAPA is almost 700$ so 150$ might not be too bad if it's all you can come up with and I can't find any down here.

Matt, where in BC are you?
I just stopped into Lordco for something else and asked about the part. They wanted $450 new.
A guy wants $150 used? For that I'd just grab a '83-85.5 and do the mod. I'm gonna do this mod myself soon, so I'd lend a hand if your in the GVRD.
Hey Logan, check out one of my latest threads. I posted a few preview pics for you before I post the whole build.
