LS-1 MAF translator vs ARC-2/ VPC

I'm interested in running a blow through setup with the translator, but I'm concerned with the fuel adjustments that will be made when intake temperatures go up due to intercooler heatsoak.

Say everything is working fine and tuned correctly on a blow through setup, then the intercooler heat soaks. When the intake temps go up, the translator will tell the ECU to give less fuel, right? Wouldn't the car need more fuel at the same boost level at increased temperature to prevent knock?

This has been asked (and aswered) before. The GM MAF's behaviour is temperature-independant and the translator reports a constant temperature to the ECU.

Since the temperature and pressure are normally used by the ECU to compute air mass (given the volume signal from the Karmann sensor) it's only necessary for the translator to vary one of the three parameters to convey the correct airmass data to the ECU.

Temperature only becomes an issue when something starts melting.

Yea my Mac played it without a hitch!

I have read through nearly this whole thread and I find it really interesting. Even though I just purchased a 2g MAS for my 1g, I'm strongly considering this new option. I have a couple of questions that hopefully you can help me with and I hope they aren't repetative which I don't believe they are. First off, what are people using for the intake piping for the draw through system besides the stock accordian? I know Dejon doesn't have one up yet but I was thinking of getting the 'long' 3" intake and then putting a 90* elbow on it to go through the old UICP location and then mounting the MAS on the end of that with a K&N where the smic once existed. I figure then it's out of the way and staying cooler than in the engine bay, what do you guys think? Secondly, How hard is tuning this? I haven't played around with the VPC at all, so I'm not familiar with what each knob adjusts. Thanks for any help.

Any help guys??

Just curious, but eventually when I get this I'll be making some runs at the track hoping to run 24psi or more with race gas. Now would it be correct of me to say that having this as a blow through would be more beneficial than draw though if I am still using my stock 1g bov which starts to leak at around 22psi? I currently plan to run this as a blow through and vent to atmosphere then (later upgrading my bov), but I was just thinking that maybe a few of us (those that aren't running low 11's) could use this the same way for the same reason and have it being helpful.

Doesn't the 1g BOV leak at idle? Unless you have sealed it correctly I thought it did? I will be ordering this setup as soon as I can get some money. I will probably run it draw-through until I can afford to re-route my piping on a new FMIC and then run it blow-through and have a nice BOV for shits a giggles...

And you can modify the 1g BOV like i did today and it will hold 30 psi no problem. Also kinda makes it chatter like a rally car a little. I installed mine as a pull threw and probly plan to leave it that way unless test show a big difrence. And on a ported 14b i doubt it. But if your running a big laggy turbo there may be some benifit.

I'm only going to say this one more time.

The codec used was the one off of www.divx.com, off of the www.divx.com/divx page. It is well-supported, and downloadable for free. Divx is not non-standard, it plays on both computers here at my house. What program and codec are you using to play it?

oh boy. back on topic please.

Not mine, its Hal's off #dsm irc channel.. looks cool eh
Hopefully he will post the results

 

[KRAZYKOREAN]

Nice..

 

[Kevin Jewer]

I Cant let this slide any longer... Its draw THROUGH, not threw. Threw is past tense for throw. As in to have thrown something. I know its a minor infraction, but its been repeated at least 5078935435 times in this long thread. Carry on.

 

[Tallen]

its just a shorter way of saying the same word. its the net not grammar class. by the way you have a few incomplete sentences in your post.

i will be installing my translator in the same spot today! YAY

wheres the cheapest place to get those reducers? extreme is best at $16 so far! i will check out some diesel shops today.

 

[P8ntBalla]

ooh ooh, go to performance diesel, those are the people welding on my ex. gate! i wanna see!

This post pretty much sums up the whole thread. For those of you that already have a 2g MAS and fuel management, have you asked yourself if it's really worth it?

I also would find it VERY hard to believe that you would see ANY spool gains at all over a standard 2g MAS. The spool restriction is on the turbine side, not the compressor side!

I applaud Ramchargers for their innovative product, and I do think it is an excellent alternative to anyone that wants a cheap blow-through sensor or has a 1g MAF without an AFC already. Kudos to you gentlemen.

But, I bet that 80% of the people in this thread would be much better off spending the money elsewhere.

I would really like to see some testing done by a neutral 3rd party source. Martin at AMS sounds like an excellent man for the job.

 

[Ramchargers]

First of all no matter how fast you go with a 2G sensor you will go faster with a GM sensor installed. Been there, done that, too many times. The spool restriction is on both sides and everyone who has installed one so far has seen a measurable improvment in spool up. If you always do what you have always done, you will always get what you always got. Time and customer feedback will tell the worth of this product, not speculation by someone who has no idea about how it works or that has never even used one. Martin already has one in his hands. He stepped up and voluntered his time to test it out. I was told he would be fair and was up to the job by a guy I respect very much. He has a unit and we are waiting on his results.

A person can run 11's on a 16g, but you can't deny the fact that a car running that fast on that turbo will run faster with a bigger turbo. Just because some one lays down 400whp on a 2g mas doesn't mean he wont pick up more hp by doing something different.

 

[ttawd3s]

I'm sure its possible to run 10's on a stock air box, but would you wanna do it, if you didn't have too ?

Very true, that is undeniable. But everyone has to admit that there is a point of diminishing returns. When does it stop giving you gains? A 4" MAF? 5" ? 6" ? 7" ? I think you see my point.

Anyone who isn't already flowing at least 2000+ Hz will probably gain nothing by increasing the size of the MAF.

Hey, don't get me wrong, I would love to see this product revolutionize DSM intake setups. Who doesn't want a better selection of parts? But let's be realistic too.

 

[RedlinedTSi]

I totally believe that new products are always great. I don't say that to mean that anything you can think of will work, but you gotta give it a try. Like Mike said "If you always do what you have always done, you will always get what you always got." This product has been proven by the GN guys, and it's just gonna take time to do the same for us DSM guys. Only track time and dyno runs will tell the truth. Can't wait to see em when they start coming out.

Umm let me just say being a third party if you will. That this Mas setup is by far better than any SAFC and 2 gmas setup. I can say this cause i have run both and tuned cars with both. I am fimiliar with the translator cause I have installed them on a few t-types. The plain fact that the SAFC dosent directly take into effect actual air mass (uses TPS and RPM mostly) at part throttle is the sole resone for doing this. Yes both a SAFC and the traslator will perform similar at WOT but from part throttle there is no comparison. There two totaly difrent animals. As for spoolup. I have noticed a 100-200 RPM increase in quicker spool (ported 14b) and this is because the translator measures actual air for the fuel input. With a SAFC and 2g setup ya get that momentary lag of fuel. Say your in 3rd at 2100 rpm. and floor it. The SAFC sees the the TPS just went WOT so foe that split second your actally going pig rich and spool suffers just a little. This is multiplyed on a real laggy turbo. This is were the quicker spool comes from. But your correct on 3rd party testing. I am sure it will come. As for me I am happy with the results.

I understand your skepticism, but let me (me being a person that currently has a 3" GM MAS translator setup installed on my car) assure you that it does make a difference. My turbo spools up much faster than when I had my Blaha or my 2G MAS on there giving more integral power throughout the RPM band. Now to be honest, with a small 16g ,I don't feel much difference up top, but I imagine anyone running a larger turbo will feel gains higher in the RPM band because the larger 3" MAS eliminates any intake restriction that a 2G MAS still creates (for a larger turbo). Plus, the tuning capabilities are very straightforward and functional.

 

[Formz]

Just think about it this way: A 2.5" exhaust is good for 11's, but that doesn't mean there isn't more power to be had with a 3". At ANY level. It's not that big of a deal just order it if ya want it and don't if ya don't!

Totally agree!!!

 

[Tallen]

i want to keep my fuel cut...
so...
"3 - OFF for NO Fuel Cut Limiter, ON to PREVENT FUEL CUT"

sounds like both say they get rid of fuel cut.
OFF has no fuel cut limiter and ON prevents fuel cut? clear this up please.

 

[Tallen]

oh yea, to extend the translator into the car...do i extend the wires to the MAF and MAS plug...or ...extend the switches??
