Need injectors for Lexus AFM, I don't know which ones.
- Thread starter aaronmancilla
- Start date
It's all in the tuning, 440's work, search on that, there are more guys on here than you may think using that combo with sucess. Again, the key is a good tune.
MKIV injectors are side feed.... they will not work
why would you stay with 440's and go lex? i guess it would still raise fuel cut, but it just seems pointless and half assed. I like to start rich and take away fuel not start hella lean and have to add a bunch.
Go with some 550's or 680's.... Lucas and PTE are the same and i think RC's are as well, they just have different stickers.

ya know i hear this from time to time and have not yet seen a single dyno sheet w/ a/r while ive done the 440s/lex afm on my bros car and it was scary lean. care to see a sheet? not calling you out but i really havent seen any proof on this. im wondering if its the old NA vs turbo cams arguement

Don't hold me to this one, but I believe MK4 NA and TT injectors are different, one is side feed, one is top feed.
Cant remember which though.

No I really don't care to see a sheet, but you can ask around here and see if some members will post there's up since it is working for some people. I personally wouldn't run 440's and a lex combo, it's prehistoric.

Form or function?? The lex afm and SAFC is 100% functional. Sure it does not have the most up to date features but it does the job and will support big numbers.... numbers that most people will ever reach like the 600+ mark.
Calling it prehistoric ......hhmmmm your point is? Look at the MKIII and the 7m people tell me every day that it is prehistoric but my car 100% functional and when i smoke em their eyes get really big, jaws open wide and they feel real dumb and say really dumb shit. I am not sure why but they do i guess they think that whatever they say is going to erase the beating they just got :evil2:
Use a different reason to bash the lex afm and SAFC combo please

You do know that the stock ECU and fuel system with ZERO modifications what-so-ever and a Lex AFM will still run at ~10.8:1 at WOT with just over stock fuel cut worth of boost... right?boostadikt said:

I don't care, nor did I mention anything about SAFC, I was talking about the lex. Does it work, hell yes it works! No reason to think why not as lots of people on her use it with sucess. Is it the easiest to tune with? No, but for the money it's a decent power adder if you know what you're doing with it. Please don't jump to rash conclusions

mrbaboon: they are side feed..... go check if you really don't believe me.
You are increasing the amount of air without increasing the fuel.... the ecu is programmed to add a certain amount of fuel at a given reading from the afm, when you increase the size you are letting a lot more air in with a higher reading without any more fuel.
i guess the ecu will try and compensate and add the fuel it can..... but the point of the mod is that the 550's compensate for the extra air and with both being added the computer doesn't know a difference so it runs at almost stock afr's... again i just don't see much reason to push the 440's
