Seriously?
How do you think it comes up with the correct pulse width and timing? By guessing? It is calculated with look up tables based on airflow and engine speed/position data.

Yea
So what's the questions here?
How it raises fuel cut? the housing is bigger and allows unmetered air...so it sends the same signal (voltage I think) to the ECU as it would if it were the stock housing...so the ECU says same pulse width and timing, but since the injectors are bigger you get more fuel per pulse...

Alright I have another question, since im running 500cc inj with the lex mod iis it possible that im runing rich on idle but lean under boost? I cheked my plugs again moments ago and the rim is black but contcts are alittle lighter with some I guess u can say white. wish I had a wideband righy now
the car seems to fall on its face after 4k rpms then comes back, doesnt happen in 1st gear, 2nd gear jyst alittle and 3rd&4th is were its felt the most. I checked for codes but it just flashes rapidly so no codes
Any ideas?

I would think you would be pretty lean all the time with 500s since the lex afm is usually paired with 550s...you will be getting the same amount of air normally paired with 550s but you will be getting less fuel with the 500s. Im not really sure though, I have heard the 550s run rich under boost so mabye 500s would run lean...
Did you ever check for the 12V mod?

all this can be corrected with a safc right? If i didn’t have 500s id definitely by 550s but i don’t see the point in the extra money assuming that it can be all corrected with a tune. And for the screw i should try putting it more in so it can be less lean? will it mae much of a difference?And did these screws come with a screw driver insert, cause mine didn’t have one so its hard to twist in and out. I bought it off a member on here
Yea, you can tune it with a SAFC.
Usually people use a dremel to create a slot for a flat head screw driver...
In would make it less lean, but if you are going to tune with a SAFC, then just set it and leave it.
I think all the way out will allow more boost since that will allow the maximum amount of unmetered air to pass

yeah tomorrow is my day off so I’m going to work on all the little nick nacks that bother me on the car and try to put that screw more in for the meenwhile. So for I’m enjoying my car and hard work except for the mpgs lol hopefully it gets better with a tune
well I’m back pretty pissed off sad angry and everything else.
code 52 really really doesn’t want to leave me alone. even after i installed new knock sensors and a harness from shaeff. took the efi fuse of for more then a minute but still that stupid pos code comes back! i don’t get it guys what am i missing?
