AFM Options

[team_omega]

I have a 3s swap and was wondering if i needed the AFM for the motor to run? The AFM and the plug that goes into the AFM doesn't match up.

[WannabeGT4]

If it's a second gen swap you will.

You probably have an RC AFM and a regular wiring harness or vice versa.

Post some pics and I'll tell you what you need.

your afm could be from a 4agZe

Ive got a afm someone here sold me and it plugs in, but runs terrible. Its obviously NOT for the 3sgte even though they said it was. The inlet is was Smaller than the 3sgte one. The part # is scratched off. So watch out for this and make sure you have a legible part # on the afm you buy

[team_omega]

here the pix of the AFM plug, the both slot on the side of the plug are the same size but i need the plug that has one big and one small slot on the sides. Please identify these plugs



and these are some plug that i need identified

thats the plug for your igniter.

I dont think thats an RC wiring harness. My colors are totally different.
You might have an RC AFM with gen 2 harness, take a dail caliper and measure the exit side of the AFM.

[WannabeGT4]

That's an igniter plug... It can be modified to fit the RC AFM. You should have two plugs on your harness that look similar to that one. Make sure to plug the AFM into the one that is going to VC, E2, and VS on the ECU. Do not plug it into the one going to +B, IGT and IGF, that one is for the igniter.

What are the part numbers for the Igniter, ECU, and AFM?

[team_omega]

Ok i have two plugs that looks like this but this plug fits my ignitor. The other one that looks like this doest have 1.(circled on pix) and my AFM needs 2. the be slightly bigger. or is it the other side(forgot)?

Post your part numbers!

What are the wire colors coming from the plug in the picture you just posted? What are the wire colors on the plug you have going to your ignitor?

The AFM part number 22250-74250
The ECU part number 89661-2B310
The harness part number 82121-2G770-C
The Igniter part number 89621-12050

but running the ECU part number 89661-2B280

i'll need to go to the shop and take more pix but the connector that was posted has these wires.


the other connector that looks the same also has the same colors but different connector. Just the connectors are different.

[WannabeGT4]

Do not run ECU P/N 89661-2B280 with AFM P/N 22250-74250. That ECU is NOT meant to be used with RC AFM!

Install ECU P/N 89661-2B310 immediately!

The good news is that all the other part numbers you listed are for the GT4RC. You'll need to figure out which one of the plugs has a wire going to VS on the ECU. That is the plug you need to use. Some where in the harness that plug will have been spliced into wires which end up at E2, VC, VS, and THA.

[team_omega]

how could i bypass this without using it the AFM? Any ideas?

[WannabeGT4]

You could buy buy a stand alone or the MAP ECU.

[team_omega]

im not too familiar with piggybacks. will this plug and play or would i need different pigtail to connect to the ECU?

[WannabeGT4]

The MAPECU needs to be hard wired but it comes with the wires and instructions for the install.

Why have you given up on the RC AFM and ECU?

because i can't find the connector that runs from the main harness to the AFM..i really need the car to be running now...its been in the shop for 1 year already...the pinout on the jdm ecu and the RC ecu is the same(i opened both) but different mapping and dont know if the wiring is the same though...so i figured if i get a piggyback or standalone.


unless someone can find me the connector for the AFM...

its in your engine bay.

[team_omega]

its in your engine bay.

the motor? yes it is dropped in already.

[lagos]

i meant the connector for the afm. the pic of the one you posted is for your igniter.

[team_omega]

i meant the connector for the afm. the pic of the one you posted is for your igniter.

yeah, i have that one and there is one that looks like that but without the bottom slot(previous pix's red circle#1)

[WannabeGT4]

Post a pic of the other plug and wire colors. I can almost guarantee that's for your AFM. If you would just get the multimeter out and check which plug has wires going to E2, VC, VS, and THA at the ECU you'll know which plug is for the AFM.

the other one could be the one that goes to your coil. i have a feeling that you are looking at the wrong plugs.
did your motor at least come with a W/A intercooler?

yeah the motor did come with W/A IC. I sold the W/A IC to alltracman78 from celicatech. I'll go check this weekend and take more pics.

[team_omega]

here some pix i took and i need to know where that go or connects to.

[WannabeGT4]

Plug one is for the AFM. If it doesn't fit bust out the hot knife and cut it up. I'd still get out the multimeter and do a continuity test between it and the ECU plug and make sure it's ending up at E2, VC, VS, and THA like I said two weeks ago.

Plug two is for the igniter. No question about it. The wire colors I can see are correct.

Plug three is for the speed sensor on the top of the transmission.

Plug four is A/C.
