maf or map stock

quebboy · Post by **quebboy** » Fri Jun 17, 2011 9:26 am

if some1 can tell me if i can run mmy turbo with my stock maf and map
sensor

understan me iam not max boosting it or race with abusive lunch max rpm reach ,,,,,,,,,, barely use turbo for the greats bov sound !!just use around 4-8 psi just for a little punch this is my everyday car so i dont want to blow it up in a mount or use it to race and punch at every corner .....

iam sure iam not the only 1 to have that simillar project ,,,every project i found everyone seem to have turbo to reach maximun horse power .... with some high pressure ......

if you have linck or anything of somesle is runing low boost with stock map maf and other part

We don't have a MAF and our MAP sensor doesn't read much above 1 BAR, so unless you want to pop the motor, you have to do something drastic to fix that problem.

map clamp (hides boost from the map sensor)

quebboy · Post by **quebboy** » Fri Jun 17, 2011 10:17 am

tanks so if i understand 1 bar=14 psi so if run at 8 psi its around o.5bar so it would work ??? without problem and no need for clamp map ??

take note i have small turbo my turbo is td05 16 g not the big 16g
i know the size turbo influance on cfm and psi so mine is not going to push that much

I don't think 1 bar is quite that high. Could be wrong though.

I know I had to switch to 3 bar on my car to accurately run over like 23 psi.

can i just use a srt4 map or,,,,, that map clamp need to be tune afther setup ??
like fuel air ratio???

quebboy · Post by **quebboy** » Fri Jun 17, 2011 1:59 pm

any have some thing to say about that clamp or any mods to map
or some1 have running stock map on turbo setup

take in mind i will not past over 8 psi

what neon do you have?

quebboy · Post by **quebboy** » Fri Jun 17, 2011 2:33 pm

2004 2l 130km on it always good maintenance my brother is the original owner and i know everithing get repair and i do some of repair in great condition ! i dont have any mods
but i have all turbo part ecept wide band and fuel system ...i wait to install... for some info i ask here

r/tguy02 · Post by **r/tguy02** » Fri Jun 17, 2011 2:35 pm

you can use an srt map if you're swapping to an srt pcm. take a look at nitehawks project log.

esteinmaier · Post by **esteinmaier** » Fri Jun 17, 2011 2:40 pm

BAR is measured as absolute pressure, so 1 BAR is the air you breathe at sea level (+/- barometric pressure adjustments)

So a 1 BAR MAP will read 0 boost at all. Our MAP sensors actually read slightly over 1 BAR to account for higher than normal barometric pressure at sea level. But that's less than 2psi of boost for most of us.

kpa is the equivalent of 1/100 of 1 BAR. So 14.7psi of boost is equal to 200 kpa, which is equivalent to 2 BAR.

So you have 3 options in most of neons:

1. Run a rising rate fuel pressure regulator with a MAP clamp. This hides the boost from the stock MAP sensor, and increases fuel pressure at a variable or tunable rate at that threshold. That solves the fuel problems, however, leaves ignition timing stock, so that limits how much boost you can run. Note that a neon 03+ uses a different computer that this tuning method will not work on.

2. Run a piggyback ECU with a MAP sensor included. This modifies the signals going to and from the stock ECU, but still relies on the stock ECU to make all the decisions. The AEM FIC is a popular choice for this, as it does have fuel and timing control. An AFC or any variation of it will NOT work since it doesn't have a MAP sensor of it's own.

3. Run a standalone engine management computer. This gives you the most control, as it completely replaces the stock ECU as the computer in charge of running the engine. It does, however, piss off the stock ECU resulting in check engine lights.

So in short, there is no easy way to turbo a neon. If you are going to do it at all, you are adding a fuel system that is capable of reaching 10psi at least.

god damm good help here guys !! so my car 2004 the first option is die
but for the other wich is te mo reliable or the more easy way to take
the srt option include !

i cant find that project log ...???

i canot use that map clamp on 2gn ??
that seem to be the easy way to go... i thinck i read some guys its work ??

some1 ever buy that clamp on ibay from dashizna .. look pretty clean

It doesn't work, but feel free to waste the money on the parts only to find out that I'm right.

quebboy · Post by **quebboy** » Mon Jun 20, 2011 9:29 am

okay ! so what about missing link and ffpr could work or it same as map cam and dont work on 2gn

P.S i listen you bro you seem to be a great tunner here and thanks to give help in that projet ....

there is few thing i didnt check before go forward with that project plz dont kill me for that !! i know ....

right i hear you !!!!

dont bo cheap ass go buy a aem f/ic !

just in case if some1 have 1 to sell !!

and probaly buy that used ... can i plug it without car just make sure is working or....

can i consider E management if i get a good price on it ???

esteinmaier · Post by **esteinmaier** » Mon Jun 20, 2011 11:23 am

The Greddy doesn't have a built-in MAP from my understanding. There's a guy on there that bought one, and battled with it for a long time. Now he's abandoning it to go MS since it didn't work.

if i use aem fic with srt4 harness that is going to be plug and play on my 04 sohc engine,,,??
can i use any car brand harness ??

sorry but iam not sure what exact eam fic i need !

if you need an easier solution, your options are:

1. Megasquirt

2. SRT computer retuned to run a 2L

anything else is going to give you constant headaches.

the headeaches is now !!!lol

so i chek for MS but its looke pretty harder to set than a piggyback ...
for srt4 comp i will be limited in my setup option

no1 ever use piggy on 2gn sohc or a wirind diagram about it ...

NiteHawk · Post by **NiteHawk** » Tue Jun 21, 2011 11:06 am

MS isnt that hard to wire up and can be used as a standalone or a piggy back.

srt computer isn't limited when you can reprogram it with a diablosport predator and a custom tune from a CMR Tuner like myself or anyone else with the Mopar CMR software...

i installed my MS in like 6 hours. that EVERYTHING installed that's needed to run it. now i did have issues tuning it at first, but those issues got solved fairly quick

I run the aem fic on my 04 r/t. I wanna switch to ms or srt computer so I have alittle better streetability. I had to unhook my o2's to have control at wot. A wideband and scangauge are not a bad idea. since he has an 04 he can check for knock with the scangauge.

lets go make the swicht i wiil buy youre !!! check ur pm !

what fic are u using ?? srt4 fic or universall fic

DingoR/T04 · Post by **DingoR/T04** » Tue Jun 21, 2011 1:25 pm

Using the srt fic.

quebboy · Post by **quebboy** » Wed Jun 22, 2011 9:42 am

there any ways to inspect the eam fic before buy it ??

DingoR/T04 · Post by **DingoR/T04** » Wed Jun 22, 2011 12:13 pm

Well I can take pics of the unit and I can take a video of the car running with it.

quebboy · Post by **quebboy** » Wed Jun 22, 2011 12:39 pm

is it possible to save fic setting of youre and use it as start point to tune mine

DingoR/T04 · Post by **DingoR/T04** » Wed Jun 22, 2011 12:50 pm

I can send it with a tune on the fic already. when you get it you pull it from the fic to your computer and save it. The fic also has a auto tune feature that can help you get in the ballpark for your first time tuning. This feature keeps it really rich and safe. I will also need to know what size injectors you have to set that up. Mine are like 620cc csrt4 injectors.
