Lexus AFM Vs. Stock Turbo AFM? Need Some Help Fellas.

[Winger]

I have two AFM's here. I bought my supra from a guy that said he put in the new lexus AFM. He has RC 550's in the car already, but I wanted to make sure that it is a Lexus AFM.

Here is the part number I pulled:
On the metal case: 22250-42020
Off the electronics: 22204-42011

Here are the part numbers for my other AFM:
On metal casing: 22250-50010
off the electronics: 22204-42011

My question is whether these are both Lexus AFM's? If so what is the difference? Also which would be better for my car?

Thanks.

the 42011 is lexus electronics i believe.. you'd notice a difference in the metal casing, one is WAY bigger...

The bigger would be better for your car, since you have 550's, that's a 25% fuel increase, and the lexus afm is a 25% increase in air.

I got two or 3 laying around none fixed my problem i was having, but the fourth which is a lex from sc400 has the same exact numbers as one off an sc300? the sc300 afm did not work but came off a running car?

 

[dusthead]

well no one knows of this problem...you asked about the AFMs being lexus or not...whats the issue?

The issue is that I have RC 550 injectors in my supra right now. The guy I bought my car from said he put on the lexus afm. I now know that he did not put that on. Everytime I hit the power band i get a ton of backfire and it won't keep accelerating. It makes sense now, being that the original afm is still on the car.

The reason I didn't notice the difference in their diameters is because I have the origianl afm on my car, I got the other one from a buddy of mine who's supra broke down.

I am installing the new lexus AFM on tomorrow, hopefully I can finally get the power out of my baby that I know it has!!

Thanks for all your help by the way!

don't forget to reset the ecu....

 

[Winger]

don't forget to reset the ecu....

Yeah, how do I go about resetting the ECU?

 

[gaboonviper85]

Pull the efi fuse for 30 seconds....or undo the battery for a few seconds.

 

[Poodles]

EFI fuse is better as it doesn't reset your radio stations

 

[azerty]

Easiest is to disconect your battery for 30 seconds or so.

Yeah, how do I go about resetting the ECU?

 

[guido]

but why reset ecu after installing a LEX afm?

 

[89supra7mgte]

to clear codes and easiest is actually pulling efi fuse, not battery disconnect

 

[isnms]

Easiest is to disconect your battery for 30 seconds or so.

Wrong. It requires NO tools to pull a fuse out for 30 seconds.
And what Poodles said

 

[Poodles]

If you have a stock radio, the antitheft is real fun to play with after the battery has been disconnected too...
