Lex AFM Results

I was asking about your current mods and fuel cut ...... your response was that you started to lean out at 18psi or so i am going to dig it up. I am sure I saved that convo

I don't remember exactly, but I'm at the end of them. The previous owner tried to dyno tune it for 18PSI but it ran too lean. I'm bouncing off 12:1 in full boost. It's been tuned damn well, I'm getting 20-25 MPG with light boosting. If you're thinking of attempting this setup, I'd recommend a Holset HY35 or HX40 instead of the 62-1, as it's supposed to be unreliable, and 550s, as running a Lexus AFM without 550s raises fuel cut past where your fuel system will actually go.

...were able to run the lex afm without any changes with the tune....

AFPR
J-tube bypass
SAFC (original, not I or II)

Equals changes with the tune

Obviously Quin and Suprafanatic are the ones you need help from. I'll bow out.

Turns out my 62-1 is a 60-1 btw

I never said or implied I was running untuned with a Lex and stock injectors. My car runs like shit for about 500 miles after you reset the ECU, and seeing as Nate's acted exactly like mine when we put my Lex on his car I'm fairly certain the TCCS adjusts to it

EDIT: Edited previous post, Nate is still on stock AFM, I'm an idiot

isnms but i am not asking for help i am just stating my results I understand lol but man there was a thread a while back where the guy was stating that he pulled the efi fuse and the ECU relearned its self back to a good tune ....... I said i was going to make a thread about it and post my results and I agree/co sign/affirm that the lex afm and the stock 440's dont work on without tunning!!!!!!!!!!!!

I dont see the ecu relearning its self with the lex afm and this is after i tested it myself.

Your TCCS will adjust, in closed loop. Not open loop which is start up, WOT, or heavy load.

Everything I have read on here .. putting just the LS400 maf on and keeping the 440 injectors = engine blown up.......no place on the INTERNET is anyone running a the lexus maf and stock fuel and having it work right.. Id put your old maf on till you can do the upgrade the way its supose to be done.. maf injectors and fuel pump....
Id hate to see what the tops of your pistons are starting to look like..

Now understand this is just my 2 cent and just my opinun....

Barts daddy go have seat or play with some more pipes lol j/k man keep doing what you are doing ......No harm meant but seriously many people have it working right with a car that has been tuned.... again my point of this thread is that the lex afm and stock 440's need to be tuned!!! My a/f are perfect and i am sure the top of the pistons are just fine. A friend of mine has been on the stock 440's and lex afm for a long time but he has a walbro and AFPR and I dont
