LS-1 MAF translator vs ARC-2/ VPC

[set3422]

You have to strong arm it in. Grease it a little, it should slide right on.

I ordered the ones with the part number you gave out, and I have a 3inch mas from the v6 gm cars. When you put yours on did they slide right on? Or did you have to work on it to get them to fit? I could not get them on I tried for an hour.

 

[smokehouse_83]

I greased the shit out of it and had two people (me and my girlfreind) trying to get it on, I was so mad she thought I was going to hit her! Later that day she told me she was scared when I got like that which is funny cause she could probally kick my ass. The only other time she told me that was when me and her put a tranny in my car I was livid mad cause I couldnt get it on, but I couldnt have done it without her. After we got it done I tried to tell her she should feel good about what she had just done and she said why. I said YOU JUST PUT A TRANNY IN A DSM!!!.

silicone reducers

i use this silicone. the best stuff i've found, and cheap compared to some others. 18 for a 3-2.5 reducer.

I tried to order some from them a few weeks ago and they told me they were dropping them from their catalog. Said they had problems recieving stock

Has anyone tried dejon tools blow thru UIP in their 1g dsm?

I just bought that along with the translator, a dejon tool intake meant for use with the vpc, and a brand new 3 inch gm mas last week. Im just wondering if anyone else has tried this kind of setup on their car and how well it is performing. I will definetly post up my results, I just cant wait to get rid of that shitty stock aircan and hacked mas. And hearing that bov vent to the atm will certainly be a plus! Now I just have to hurry up and wait for ramchargers, on back order...

BTW Im also having a ported Big 16G, ported 2g exhaust manifold, and a hallman pro series evolution boost controller. The car will be a whole new beast when its all put in!

got my Dayco connectors on today. what a pain!

Okay, I tried to find this, so if it was already asked..dont flame me, Im still fairly new.
Can I use an aftermarket GM MAF??, like a Garnatelli, or JET???, because I actually have an aftermarket Garnatelli available, its a replacement for the 3" LT1 I believe..flows better then stock, no restrictions. Or is it onlu usable with a factory GM MAF?

Also, what other advantages are there from mounting it push through, besides being able to vent yout BOV?

 

[Bohrn]

Hey fellow Canadian

I believe you can use aftermarket(Granatelli et all) mafs as they have to be identical electric signal wise to interface with the factory computer.

As for blow thru advantages, the big one is a big assed straight thru pipe to the turbo, with just a filter on it, putting it wherever you want(cold air) that you can find room for.

best of luck, and post it up on DSM.CA when you get it sorted so we can all see it.

Ramchargers has repeatedly discouraged people from using the aftermarket MAF's. Email Mike directly if you're still interested and want to try it.

aftermarket maf = not good idea

 

[jazzyjay]

Granatelli makes two sensors. One of them is 50 states legal and the other is not. The MAF are pre calibrated. I don't see why there is a problem the same signal is being sent from MAF. The MAF is calibrated to make a lean situation, but you have the translator to compensate for that. Ramchargers biggest following for the Translator is the GM crowd and beleive me one of the first mods they make is an aftermarket MAF.

There are tons of benefits from using the Granatelli MAf over the factory MAf. These are the biggest two:

*Dyno proven to add 10-23 rear wheel horsepower(on the GM test car)

*Flow bench tested to provide 47% more air than stock mass airflow sensors


Yes I own a F body with the translator and the Granatelli MAF for over 8K miles.

100% is ideal on all trims. WOT is different, it ignores the O2 sensor. Try here:

But when do you know where the limit is when you are leaning out your low trims? I have noticed a huge decrease in fuel economy now that I've riched it up down low. I have it at -2%, and had it at -5%, but where is the limit that I should look for?

I honestly don't worry about low trims a lot. Mine run 120-139 at idle 3 and it really is grossly over fueled. If I richen any more it to make the low trim look good, it stumbles and backfires badly. As it is, at parking lot speed it's constantly rumbling from unburned fuel in the exhaust. These numbers are influenced by underhood temps and fanwash. The only driving effect I get is slight throttle surge before the car is fully warm. Are you tuning with a SAFC on top of the MAFT? I don't otherwise uderstand the 2% reference. Listen to your car in this case. Does it run right even though it says it's lean on the logger? Is it crappy when you richen it up? Scott

Okay, I re-read some of the previous posts, decided to go with a stock MAF. I traded the Garnatelli for a stock LT-1 MAF, and $$$ to a gm guy.

I have another problem, as of now I dont have a datalogger, just an A/F guage and boost....is this enough to tune the translator??

My car is basically stock with the exception of free mods, and Im getting a 3" exhaust very soon. I dont really need a datalogger now since I have a 14b and stock injectors, so I never bought one.

thanks for any help.

 

[Bohrn]

to tune with anything you need a datalogger.

They are cheap now, cables can be had for $60, the software is free, and a used palm is like $75.

Check it out on the canadian boards, you will get the same answer.

Not to be an a$$, but you should hve gotten alot more other mods before you got a GM Maf system. You won't over run your stock maf until you are into the mid 13's at least, and you can tweak it to make it go even faster than that.

 

[CrazyCanuck_awd]

I dont consider someone giving me advice to be an "a$$", Ive been into cars for a while, just this is my first DSM, so thanks for any help.

Its just that with all the N/A cars Ive owned, the first few mods were directly related to improving intake and exhaust flow....e.g add headers and full dual exhaust, change intake/carb/air cleaner for a better flowing one...then do other things like heads and cams.
On the upgrade path it shows the air intake as being a first mod, so I figured the DSM might respond the same to freeing up all restrictions on intake side as domestic V8's ....

Thanks for the advice, I guess Ill hold on to the MAF for a while untill I upgrade intercooler, turbo etc...

 

[set3422]

what tuning on MAFT???? Remember good old days for VPC 4 buttons tuneability and the only button that works is the GAIN button. What???? GCC suppose to double the # of buttons and improve my panel lightings. If it's all too familiar with you, welcome to MAFT 3 buttons tuning. Idle button doesn't do anything FOR ME. MID and WOT buttons seem like only increase fuel, but can't decrease pulse width. Better off playing with AFPR.

The MAF is an airflow improvement over the 1G MAS but I would hang onto the MAS until I got confirmed missed counts. The tuning improvement on stock injectors is probably not worth the effort. The breaking point on my setup was when I upgraded uicp, licp and upgraded smic while running 12psi. When you get a logger and find the mods causing over run then go to the MAF, but expect to need an injector upgrade as well. I found that at that point the MAF improved airflow enough to jump DC to well over 100%.

I've been kind of dormant in this thread for a while, but I have to speak up.

My car was the test-car for the 1g translator, and had a big16g @ 12psi, 2.5" turboback, and the rest stock (including 450cc injectors). The MAF-T and a 3" mas made a HUGE difference over a stock 1g mas. At that boost level, I was just starting to run out of injector, but this was on a b16g. If you're overrunning the MAS, you'll probably need injectors soon enough, but I honestly recommend exhaust and a translator as the first two mods to any DSM.

The MAFT is not a basic mod. It's a support mod. It certainly started as an alternative to 2g MAS upgrades and blow through systems. It's beyond his needs as his mods list only says freebies. The computer does a better job on a stock car in my book. The first upgrades I would recommend are tune up, mbc and exhaust on a 14b. Don't you work for Ramchargers now? Scott

True, but he can install the MAF and not touch any of the switches. That would give stock values to the ECU. And he would still benefit from the increased flow and decreased spool time. I think what you're trying to get at is that the MAF will make a bigger difference with a bigger turbo, which is absolutely right. But that doesn't mean smaller turbos still won't benefit from it.

 

[Tallen]

my car w/ t25 made up .5 on the track with just a lil fuel tuning. cant beat that!

 

[bearman]

Tallen, please expound. Are you saying you went half a second faster in the 1/4 mile with just the translator and gm maf? (and some tuning)

 

[Tallen]

yup....i went to the track 2x and ran 15.0 flat. with the maft i was able to tune the car and actually got some good topend. i expected better than a 15.4, but my exhaust broke on the second launch (it was rusted and i got wheelhop). so that ended my day.

track times in 2-3 weeks with the ext dumo, FMIC, and sm16g
