LS-1 MAF translator vs ARC-2/ VPC

[xinfiniter]

So for the 2G guys.....do we order the 3000GT translator or the Eclipse translator??

 

[dsmsleeper]

It has been said that the 2g uses the same plug as the 3kgt, but we'll see what the official word is.

 

[dsmsleeper]

DSMraver - what size injectors did you have on your test car with the 16g?

I assume that you couldn't use stock injectors with this setup(GM sensor and translator). Since 550s are 'suggested' to use with the 2g MAS upgrade, unless you use an AFPR. -Just making sure.

 

[DSMraver]

Stock as stock my friend... Like I said, I was glad we used my car, since it was so close to stock, save the b16g. In other words, yes, 450's. Now, granted I was only on like 10ish lbs of boost. That MAS flows a LOT more air than the stocker, and I would recommend 550's or an AFPR to run higher boost on pumpgas. Not to mention fuelcut avoidance.

The Translator (IIRC) has the capability to adjust for 660's, or other larger injectors.

 

[BobTurbo]

The translator can be used to tune for stock thru huge. The base setting selects the full-range air correction for your chosen injector. it can be adjusted in 5% steps to cover the full range of available injector sizes.

You should order the translator for a DSM if you have a DSM. The Translator for a 3000GT is set up for 6 cylinders and would run a little funky on a DSM.

will it plug in though, seeing as the 1G and 2g's have different mas plugs?

 

[1 fast POS]

Pardon if this has already been discussed. What about fuel cut? Will the readings the ECU sees delay fuel cut, will it ever cut? Can you tune fuel cut to wherever you want it with the translator adjustments?

How is Mike? I hope that it wasn't serious. Let us know, he's a hero now. Well, he will be soon.

 

[4wd-Eclipse]

nine5raptor the mas translator as shown in ramcharger.com has two plugs. One will be connected to the GM mas & other to the original mas plug.

So no need to wary about 1G & 2G mas plugs.

 

[GVR-4]

As far as I know, the 1g and 2g use different MAS plugs.

They do.

Yes GVR4 you are correct the 1 and 2G MAS have different style MAS plugs. When putting the 2G mas on a 1G splicing or changing the pigtail is necassary. In this case it look like that is DEFINATELY a 1G harness pictured. But the pictured translator on the ramchargers site for the Stealth also shows the 1G plug it seems. This leads me to believe that the ramchargers puctures are not necessarily application specific. I think that Bobturbo needs to specify weather they are 1G and 2G specific units or not.

Fuel cut is a function of Karman hz exceeding the maximum limit at WOT, set by the ECU. This limit is normally pushed further off, by compensating with larger injectors and tuning the airflow signal subsequently leaner with a correction device (enter the translator box).

So no, not by itself will it eliminate fuelcut, but it does provide a means to stave it off (ala hacked mas), assuming that you have larger injectors, and why wouldn't you?

just wanted to add: assuming the stock fuel system. The ecu is seeing the max air that the 450's at stock fuel pressure can support.

edit: I said this to provide the reason why the maximum limit is set as it is. If you have other injectors, fuel cut becomes meaningless.

[DSMraver]

Not to nit-pick, but fuelcut as determined by the ECU, based on several inputs, but it has no way of knowing what fuelsystem you have, nor does it matter to the ECU.

My point was and still is: exceed the limits in the ecu, and you get fuelcut, 450's or 1000cc's - no matter.

[edit: let's get back on topic...]

 

[BobTurbo]

The translator has a fuel cut defense built in.

For this reason:

Assume stock injectors
Assume a BIG turbo.

Add extra fuel under boost using:
Aux injector system
Propane
Alky

The extra airflow will cause fuel cut.
The Translator has an output frequency limiter
to prevent fuel cut. The limiter can be turned off
for those guys running modded chips.

[DSMraver]

I stand corrected... Things that didn't come up when we were testing, must have been that whole "standing out in the cold" factor.

so what are you saying? how much boost can we run before fuel cut? is it like with an afc where we can make trick the maf with larger injectors or is this something that will limit those with no modded "chip"? (i assume your talking about an eprom ecu). basically if we put bigger injectors in and tune the translator for, say, 15% less, will we still see fuel cut at the same airflow? or will the ecu be "fooled"? thanks for your time with the questions.

 

[BobTurbo]

The AFC 'trick' of underreporting airflow to compensate for large injectors is the same principle as the BASE setting in the translator.
It will push the fuel cut point up in the same manner.

Leave the fuel cut limiter on anyway so in case the boost overshoots a couple pounds on a good run the fuel won't be cut.

The only time to turn the fuel cut limiter off is if you have a modded EPROM ECU with fuel cut removed and/or the injector size changed.

(John, where are those pic's and flic's? Gotta get them posted/hosted somewhere.)

 

[FastRthenU]

So let me get this straight. The same unit can be used like the stock maf (Pull through) and as a blow thorugh(Mounted between the bOV, and TB)? It can handle High psi when used as a blow though(30psi).


by the way this is a great product. Thanks

Yes.

Bob, I'm tryin' buddy! My roommate keeps telling me "yeah, I'll get those ripped off the camera tonight". Well, I'm getting a little impatient myself, since everyone on here wants to see the setup! It makes such a difference, especially those comparison shots between the 3.5"-3"-1gmas.

I'll just ask him for the software and cable, and rip them myself tonight.

 

[Tallen]

what size MAS would we need to put in the UICP to vent to the atmosphere?

 

[TheObiJuan]

use the LT1 3" MAF and some silicone reducers after the MAF ends.
that is unless someone like dejon wants to create some 3" to 2.5 inch smooth tapered maf ends with a lip that bolt onto the MAF.
now that would be awesome.

 

[RedlinedTSi]

YES!!! I agree!!! Tapered MAF ends would be great.
