LS-1 MAF translator vs ARC-2/ VPC

[lxlaw]

I was going to say i was told that i could run 660's on my big16g and that would be enough to upgrade to a 20g later on with no other changes.

Why the hell are you running 44psi of fuel pressure on a ####ing 14b? It should be 38.

 

[nine5raptor]

injectors are usually rated at 43. if you want 550's to flow like 550's, then you need to have your fp at 43. at 38, they will flow less.

 

[Formz]

Thats quite obvious. He's maxing out his 550s because he's running insanely rich. He should turn his fuel pressure down to to a more reasonably level and I bet you $100 he'd be in better shape. Not to mention he's running 15psi on a 14b with oversized injectors, he should be at really low (like -30) on his AFC because of it.

No I am not running insanely rich. And just to double cheak i just came in from running over 20+ pulls tunning the thing. I droped FP back down to 38 with Base setting at 4 and idling nice at position4 mids at 4 and WOT at 5. Thats right i have to richen up all settings. This is were i will start cause i will not bore you with the 5 previouse passes of masive lean knock were i started with the base @ 4 and all others at zero. anyway with the above settigs the best i can get is 14psi. It pulls great 1-2 and in 3rd i get about 3 counts and 4 theres about 10 and tapers off slowly. No i dont have any boost creep. and my injectors start to max out in the middle of 3rd @ 21MS. I even tried throwing some 7es plugs in gaped at .28 to see if it helped or changed anything and it didnt. BTW i have no SAFC just the MAFT with a 3" Mas. So how about givin up that $100.

Ok what i said right here is a ball face lie. I stand corrected. I just went out again starting from scratch. Base setting at 4. mids and WOT @ 0. FP @ 42. the thing runs balls to the wall now. With 3 counts of knock. this is only @ 15psi. Iwill tune somore tommorrow and post results. Thanks Forms for calling me on this one I needed the kick in the head. Now can a Mod delete my crackhead post about needing masive injectors?

O yea BTW my inj PW is now no more than 15MS. so yea its was just a hair rich.

Told ya!

hey guys, i havent been positng for a long time and the reason is simple, the traffic at this site is huge!!! thats not a bad thign, but i prefer a more slwoer moving site, one that i can keep up with the posts, cuz i am usually a post whore kinda person. i dont have time ot read though all thsoe posts (21 pages worht on my forums) so i wanna ask a quick question, does this ramcharger translater work? should i get one considering i only have a k&n, hacked mas and three inch turbo back exhaust with no cat? i have been wanting a vpc for the longest time, but if i can get the same functions without the high price tag i will do it. also, if i wanted to, could i add extra wire and mount the translator in my car instead of under the hood? please email me the answers at [email protected]
i greatly appreciate the knowledge shown here at this site, but like i said, its hard to try to post and keep up with topics in the conditions this site has (again i am not complaining, i think its great that this site has a huge amount of memebrs reading and sharing their knowledge with others.) thanks so much.

 

[RedlinedTSi]

OK, I was with Motohead in thinking I was maxing out my 450s with my 14b. I am getting 22ms Inj. P/W at 17 psi with the Base at 3 and everything else at 0. The reason I think I'm maxing out is cuz I can't get my O2s over .84. My next step was going to be to richen up the MID and WOT settings, but ya'll say there's no way I'm running lean. I know an overly rich condition can cause knock, but can it cause messed up O2 readings too??

If I may, I'd like to say something about fuel pressure and injector sizes. When I had my 450s with a stock pump, I was running lean due to my intake and exhaust mods. More air was coming through but the fuel wasn't getting added. I didn't have a logger at that time and was gauging lean vs. rich by checking my spark plugs for color. But I did have an only up AFPR.

In a case like this, I had to increase the FP to add more fuel. Which is in effect like installing larger injectors. A band-aid solution, but it worked. Band-aid because I didn't have the right tools to monitor what was going on.

Someone debated that injectors are rated at 43-44 psi and if they lowered their FP to stock pressure the injectors would in effect be something like 580s or something like that. There's nothing wrong with under utilizing their potential. If you actually do need to add fuel, have 450s, 550s or whatever, you could then increase the FP or adjust your MAFT or AFC.

I guess what I'm getting at is that with an AFPR and a MAFT and/or AFC = more tuning possibilities. Perhaps finer tuning possibilities.

Okay here's an analogy. Your car can go 130mph. Do you always drive at that speed just because the car is rated to go that fast? Same thing here.

Sorry for the long reply.
Thanks

I really don´t understand this part.
If you lower the FP they would work as if they were smaller, not bigger.

 

[JJNovo]

Holy sh*t. I just went back trying to find the post I was talking about, all of this stuff has already been beaten up quite nicely.

Anyway they were 660s and as far as I remember, the poster was wanting to run a higher FP (44) because that's what the injectors were rated for.

I'll just shut up. But there is tons of good info just in this thread. To bad there isn't a way to organize it.

Ok me shuts up.

does anyone know if a vendor sells the blow through upper intercooler set up for a 2G like DejonTool has for 1Gs?

 

[16g-95gsx]

Please dont jump on me for not reading, as I have read about 10 pages of this thread, but its just too long to do a full out search. My question is, the honeycomb is fully removable right? If it's removed is anything effected?

Isn´t the one that Dejontool sells for a 2G too?

not from what I see

 

[pilotleston]

Check this out: Dejontool

you will flow more air and it will throw the calibration off therefore causing you to need to tune richer than with the honeycomb in.

here is an update on the 2G blow thru upper IC pipe:

I talked to Dave Johnson of Dejontool and he said and I quote:

"2g is too difficult, Dave"

I know they do make a blow thru set up now ......weird.

Why do they announce it on their web page? (the link I gave you above).
I really don´t understand. Did you see the UIP on that link? It says 2G! : )

I did see the link you posted , but I saw it after i had sent the email. If you look closely you can tell that pipe is also in a 1g.

 

[pilotleston]

Sorry but didn´t mean to bother you so much.
I don´t recognize a 1G from a 2G really, so I just believed what the page says.

Regards

 

[talonted_one]

well here is some help for you...

look at the strut towers, they are too vertical to be a 2g.

the fuse box is not the same as a 2G.

the engine could be in a 2G as we all know but it is a 1g motor and intake manifold and CAS.

the cruise control box is from a 1G.

I hope this helps you out.

 

[P8ntBalla]

that is a 1g.

 

[Kevin Jewer]

There is no difference between what is in that picture, and what I would need to bolt this up to my 2g/FMIC. But I will make my own pipes either way. Look at how ridiculously thin that TB flange is. It may not have to be as beefy as the 1/2" steel flange on my VP elbow, but I dont like that one.
