Can I say Screw MAFT and tune with SAFC?

[Sayajin]

Hey guys. I have read a bunch of the tunning with MAFT and SAFC posts but my question does not seem to be in there anywhere.

I am about to purchase a GM MAS and MAFT and of course all the other stuff needed for the setup. I was wondering if it is possible to not tune with the translator and just do all of my tunning on my SAFC? btw, I dont mean to not use the MAFT, I know they are NECESSARY to run a GM MAS. I mean like just install the translator, leave everything at zero and make all the changes via the SAFC. Thanks a lot guys.

Yes you can do that. You can hook up the translator, and leave all the dials at "0", and it will pass through an unaltered signal that then can be changed by the safc tuning. I am going back to the safc on my car; just not happy how my car is currently tuned with the maft dials.

But you may still experience some slight problems with the new maf. It all depends on your setup, where your maf is, if it's screened or not. And I've heard 1g's are a little more picky with the translator. Either way, give it a shot...

IMO the best use of the maf is not to hook up the rpm wire and just set it to the injector compensation for your setup, leave the rest of the dial to 0 and do the fine tuning with the afc.

Another question... Will the 2G MAFT and 2G Harness really work on a 1G? I know this sounds dumb, but I have a friend trying to sell me the one he was using for a VERY good price (he blew up his engine). He has/had a 90 GST and was using this setup. Will that really work?

Sorry but im asking about the 2G MAF Translator. Not will a 2G MAS fit in a 1G. I know they can. I am asking will the 2g Translator work in the 1G properly as my friend says he is running. Thanks a lot.

Yes it's possible, but then why even buy a translator? I say use the translator to get new, but good base settings. From there you can use the SAFC to fine tune it-well, as good as possible without a logger that is.

 

[kpt4321]

If you're going to tune with the SAFC, why would you buy a translator in the first place?

If you're going to buy a MAFT, use it to tune instead of the SAFC, and sell the AFC. If you're stuck on using the SAFC, then don't bother with the translator.

Yes, and the wiring information he just sent you will tell you how to wire the 2g translator into a 1g.

 

[Sayajin]

Oh sorry about that man. I didint even consider that is what the link was for! Thanks a lot.


Oh, I thought that you HAD to buy a translator in order to use a GM MAF. If I had known that I can just use my SAFC and not get a translator at all, I would have gotten a GM MAF long ago... Or is the MAFT really THAT much better to tune with that I should get it and sell my SAFC? If not, is the install the same using an SAFC as using a MAFT? Thanks a lot guys.

[Squackdiddy]

what about using the GM Trans. just to compensate for bigger injectors and use a dsmlink to tune? or alll you need is the dsmlink? because i kind of want to get the blow throuhg setup .

i agree. this has been the most efficient and easiest way to do it on all the one's i have installed.

You can't use the GM MAF without a translator.

The point is, the MAFT will do everything the SAFC will do, except have a blingin' blue screen to impress the hoochies.

As such, there is no point in having both of them. Stick with the stock MAF and get a SAFC, or get a MAFT and don't bother with the SAFC.

Why spend 200 dollars on the translator, and another 100 dollars on the MAF, if you're just going to end up using a SAFC to do the job the MAFT was designed to do?

If you're going to tune with the SAFC, then don't bother buying a MAFT, that's just redundant. The only two choices as I see them are stock MAF + SAFC, or GM MAF + MAFT. Not both.

not this crap again..

THEY DO DIFFERENT THINGS


MAFT translates the hotwire to karmen

SAFC tunes.

simple concept.

SAFC does much more precise tuning than the MAFT. another simple concept.

 

[mitch83]

so do you or do you not need a tranlator to run the GM maf. I've read and researched yes you do. My deal is I want to tune with the SAFC but I want to vent to the atmostphere later as well as get rid of the big ass ugly stock MAF that just gets in the damn way of everything.

I'm going to have to agree with HighPSI TSi Guys here. I have not been pleased with my tuning the gm maft (1.37 version) has done on my 2g. So I am going to zero out my maf and go back to using my safc; we'll see if that feels any different.

But I'm keeping the maf-t in there because I like to vent...

The MAFT tunes just as well as the SAFC does, so long as you are using V 2.0+, which is what every new translator comes with.

The MAFT converts and tunes. The SAFC only tunes. They have about the same tuning ability. You make the choice.

The stock ECU can't understand the signal that is coming out of a GM hotwire MAF. The translator converts that signal to something the ECU can understand.

You opinion isn't worth shit if you're using an outdated version of the MAFT software.

V 1.37 doesn't have a high enough resolution to give you a precise tune, if you are a good tuner. Therefore, you need a change. Your options are a 200+ dollar SAFC, or a 30 dollar upgrade to V2.0+. I know which choice makes more sense, do you?

Yes you need a translator to run a GM maf on the car. if you want to vent, make sure get a blow thru setup in you UICP, not your intake. To get a good idea, look at my gallery, I have a new engine bay setup without that annoying ass stock maf.

Obviously you didn't read my post moron. I already HAVE the safc installed from before the maf-t days. So I can either (A) go back to using the safc which I never had problems with. or (B) Pay an extra 30 dollars for the new 2.01 version, of which when I signed up for it was a 3 month wait. Now apparently their is no wait. So now I ask you, which one is more cost effective?

Maybe eventually I'll get the latest maft-t chip, but I haven't had a good experience with my maft-t or with Mike from fullthrottlespeed. Clipping resistors for baro fixes, really bad idle which a lot of other 2g's experienced on the old yahoo board, orginally 3 month wait for the new chip. Maybe I'll wait until all the bugs in 2.01 are ironed out, so that when 2.5 or 3.0 versions come out, I don't have to pay another 30 dollars to upgrade yet again.

so the MAFT can do 1% incriments now? until it can, it's inferior by far to SAFC

Buying the upgrade and selling the SAFC.

Thanks for kind words though.

You claimed that the SAFC was neede to tune the MAFT, which may be true in your case because you are running the older version. However, it's not true with the newer version.

experience with my maft-t or with Mike from fullthrottlespeed. Clipping resistors for baro fixes, really bad idle which a lot of other 2g's experienced on the old yahoo board, orginally 3 month wait for the new chip.

The resistor thing was a problem with the individual cars, which is why a bunch of MAFTs that were the exact same thing only did it on some cars. Think about it.

Really bad idle is your tuning problem, and nothing else.

Sorry there is a wait for a good product. I know that most of the other good DSM vendors will get you stuff right away (obvious sarcasm).

Maybe I'll wait until all the bugs in 2.01 are ironed out, so that when 2.5 or 3.0 versions come out, I don't have to pay another 30 dollars to upgrade yet again.

What bugs?

 

[kpt4321]

1. Since when is the correction increment the only thing a tuning device is judged by?

2. You can adjust it in 1% increments, with soem creative use of the knobs.

3. Show me a situation where a 1% airflow change is really that much better than a 2% change. I guarantee you that 99% of the people using these products, and 99.9% of the roads and tracks these cars are driven on, will not notice the difference 1% of fuel makes.

With the other changes that occur (heat soaking, injector dead time, VE changes, etc), a 1% increment in tuning is not something to be concerned with.

Your glorious VPC tunes the whole damned curve with one knob. Now THAT is precision.
