Bigger MAF= run lean
Bigger injectors= run rich
Bigger MAF+Bigger injectors=just right, or so his theory goes.

I dont think it will work, but thats basically what he is saying.

I think he meant he's going to get a pipe that runs air around the maf from another filter... which still doesn't make it work. He didn't say anything about bigger MAF or bigger injector. if you add in more unaccountable air then it will run lean no matter what size the MAF... you have to start dumping in fuel and it'd be very hard to balance out even with bigger injectors.

Read the very first post, thats where he said he will run bigger injectors.

James · Jan 27th, 2003, 12:39 PM

what the hell does the first post have to do with it? of course you have to run bigger injectors when you boost? I'm talking about his MAF idea...

mpg9999 · Jan 27th, 2003, 12:42 PM

Alright buddy, your still not getting it. Please read his first post again.

mpg9999 · Jan 27th, 2003, 12:44 PM

Here, lemme help you.
"i was thinking if this might work, and i kinda borrowed the idea off of one of my genious friends, but if i dont upgrade my ecu, and run a bigger MAF (such as a 95 or 96 240sx) and bigger injectors (such as 370cc 300zx injectors)"

He said he wants to run both a bigger maf, and bigger injectors.
now, let me say this again:
Bigger MAF= run lean
Bigger injectors= run rich
Bigger MAF+Bigger injectors=just right, or so his theory goes.

Ok what is YOUR point? I see in his first post he is adding in bigger injectors and bigger MAF... ok he can do that? so what that's obvious! without the ecu he still would run like crap and with that stupid air bypass he'd run like crap so unless you're suggesting something else that I must be OBVIOUSLY missing, please speak up.

It will still run like shit. Need ECU upgrade to handle the "Bigger MAF+Bigger injectors"...............Or else I see a blown engine.
Period.

still doesn't work, sorry, you can't just add two big things together and not change the ecu that controls them and expect them to balance out.

mpg9999 · Jan 27th, 2003, 02:02 PM

Yes, I know it probably wont work. I doubt very much that they will be able to balance each other out. My point was that you guys werent understanding exactly what he was saying.

James · Jan 27th, 2003, 02:03 PM

no i understand exactly what he's saying, I don't understand what you're saying.

mpg9999 · Jan 27th, 2003, 02:08 PM

All I was saying is that you guys didnt understand what he was saying.

James · Jan 27th, 2003, 02:11 PM

damnit this is stupid... wtf do you mean I'm not understanding? can somebody explain to me what I'm missing here?

mpg9999 · Jan 27th, 2003, 02:12 PM

didnt. past tense. I see that you understand what he was saying now. And theoretically his idea works, although I dont see how he is going to be able to match up the injectors and MAF.
