LS-1 MAF translator vs ARC-2/ VPC

That will burst under repeated boosting. I used those couplers for my 2.5" UIC to SMIC connection. They will split at the seam where the coupler actually "reduces".

Not if he uses a draw though setup. Then they will see no boost.

ill just go to home depot and see whatelse there is. or ill just wrap these in duct tape or something. (i could careless what it looks like under my hood, as long as it works.)

anyone know if i can cut the screen out of the new mas. im slightly confused on doing that or not.

Mike,
I read on another board that there is a switch on the translator to change from the 1G MAF calibration, to the 2G MAF calibration? Is this correct?
Also, how did you arrive at your 1G and 2G MAF calibrations? Was it on a flowbench? Do you have any test results for how closely it matches up?
Is there any problem in running this without the RPM wire hooked up? I am asking because I have a 2G, and have no desire to use the translator to tune, I already have something to tune with. I don't need the airflow clamp, RPM or airflow based fuel settings. I just want it to plug in using the 2G connector, no additional wiring, and have it work just like stock, only less restrictive.

Thanks,
Brad

The 1G translator has a 1G connector; 1G and 2G calibrations inside
The 2G/3S translator has a 2G connector; 2G and 3S calibrations inside

The calibrations were obtained on a flowbench, they match darn close.
(We've been doing this for a while)

You can leave the RPM wire disconnected, the unit will run absolutely fine.
(Cut it, coil it up, whatever)

Bob

so the purpose of the rpm cable was...

 

[BobTurbo]

The RPM is used to determine when to use the MID adjustment dial and when to use the WOT adjustment dial. Brad is going to leave the dials alone and (presumably) tune with DSMLink.

The RPM signal is also used to calculate the fueling factors when running "Contoured" WOT fueling (to compensate for NOS, Propane, or Alky)

Heh sorry guys I only dedicated 1megabit of bandwith to that file
My connection is at 100% utilization still. My log of users connected is huge . So yea I wouldnt doubt the 2k per sec download speed. Sorry. I tried.

I will leave it up though for everyone still downloading.

 

[dsmturboawd]

the purple wire MUST be used, correct? im lost in the instructions as to where this wire goes.

 

[Bohrn]

Raver, it looks like you used the stock intake pipe (Mas - turbo). Is this so? Or just looks like it.

 

[DSMraver]

Stock intake pipe, stock intercooler piping except the MAF translator stuff.

 

[draculia]

dsmturboawd, as stated many times before, yes you can take the screen out. also don't use rubber you cheap bastard! j/k for quick shipment and good prices on thermalflex silicone hoses go to extreme motorsports. for purosil silicone hoses and prices that are a little cheaper but shipping can take a very long time, go to baker precision. extreme is now my only source for silicone hoses. the quality is perfect, and i waited a month before cancelling my order from baker. atp has the worst silicone i've ever seen.

also, my order has been placed, i will use blow through, but that's because i have a tial bov on the way too. i'm redoing a ton of stuff, and a fmic is one of those. i'm making the piping myself and wanted to run the tial bov for a long time, it seems like the perfect marriage of parts. my car won't be running for a while though.

Hey i want to thank you for the pics and the info. As soon as i get mine running i am going to buy this instead of the SAFC first and may get that later. But this is huge. I am going to buy a big 16G and a new EVOVII manifold. So this will work awesome for now. Again thanx for all the speedy info on this product and helping us out. I hope these people have a big supply of these because they are going to go like hotcakes. Laters and good luck all!!!

 

[j.d.roost]

The 1G translator has a 1G connector; 1G and 2G calibrations inside The 2G/3S translator has a 2G connector; 2G and 3S calibrations inside

So if I have a 1g with a 2g maf. Would I be better off using a 2g translator ( same or close to the same safc settings) ?

Or should I use the 1g trans. and retune? ( no big deal)
I have both connections (1 or 2g) wired into the factory harness right now.

Thanks
jd

Just installed the translator pull threw with 3" GM mas with 550s. This thing is great. Tho i may have one of the first trouble shooting question tho. I pulled the battery loose to reset the computer and didnt notice it befoer but the green led was on steady after starting it up. acording to the sheet it said "Mid". Does this mean the mid was not reseaving a signal or was this becase i reset the computer? It did go away later after i did a shake down run then i just brought it back and parked it. I did a few log runs and its so much smoother its running a little rich and actually had to richen the idle a little but havent messed with the mid and WOT settings. I just installed it in 15 minutes but tomorrow I am gonna extend the wires and run it into the cockpit. anyway i will have a better reveiw tomorrow. i am gonna hurry get some sleep so i can wake up in a few hours and set it up right.

I need to know if 3.5” Maf sensor of 98-02 Comaro will work with the TRANSLATOR or not? I got one free.

 

[TheObiJuan]

for the 100th time, yes.
it will work.

 

[TOTalon]

I am wondering if a less expensive version of the translator with no tuning capability will ever be offered for those of us who already have fuel management systems.

 

[TsiArt01]

Just showing interes to the subject

 

[DrZiplok]

You're basically asking for a completely new device at that point; I don't see how it'd be much cheaper unless they were selling them in very substantial quantities.

 

[brads]

4 or 5? rotary switches removed, minus the RPM sensing wire and circuit, and maybe even remove the dip switches. If they wanted to do it, it would cut their production costs. They might be able to knock $20 or so off the retail cost by doing those minor removals. Thats just a guess though, I am surprised its selling as inexpensively as it is right now, with the components it has on it.

[HighPSI TSi Guy]

any news on an Upper IC pipe made for this by dejon or comparable for a blow through setup with this?

 

[4wd-Eclipse]

good question

Dejon is making an INTAKE for it, not an upper IC pipe.

This is from Cam's post on DSMTalk:

"...BTW everybody, i was at dave's house this weekend (dejon tool) and I saw the first experimental blow through pipes...damn they are gona be sweet. it will just replace the long throttle body tube that he makes for the fmic kits, it expands smoothly and shrinks back smoothly before the "bend" to the tb. The gm maf will be inbetween the head and the battery if that gives you a better idea of its placement. Dave said the draw through pipes will be exactly like the vpc pipes, only with larger or smaller openings depending on your turbo and maf size. ...

 

[Formz]

Ah ok, I didn't read the thread on DSMTalk. I only saw them talking about the draw through in this thread.

 

[DCJ98GST]

I would not want a translator without adjustments and here is why:

It seems to me that the fuel adjustments on the translator are superior to the SAFC. The bad thing about the SAFC is that it has throttle based adjustments that is not always very acurate. Here is an example:

Say you have just an S-AFC and let's pretend that you have a laggy turbo, where boost begins at 3400 rpm in 4th gear. So what happens, if you are driving around in traffic at around 2800rpm and mash the throttle? The SAFC sees that you are at WOT and kicks over to the high fuel map (since it's basing its map on TPS) and begins dumping fuel despite the fact that the car hasn't begun making boost yet. So, the car now runs shitty for 600 rpms because it is rich, and bogs from the overrich condition until the car hits boost. This over rich condition will make the turbo lag seem even greater.

The translator fuel adjustments are based on actual air flow not Throttle postion and should eliminate this problem.

The more responsive spool time may not just be because of the increased flow but also proper fuel mixture at the lower rpms!

The translator should be used in conjunction with the S-AFC for fine tuning, but the bulk of the tuning should be done with the translator.

I have tried to read/skim all of the posts in this and the other threads, and if I am wrong please tell me.
