SAFC-II and Maf Translator, why both?

[Gravy]

Last summer in installed a Maf translator, and also have an SAFC, now i know the SAFC gives you more control but i could live with just the GM Maf translator for now. Can anyone give me a good reason to keep both? Otherwise i can pull the SAFC and sell it off.

Most of the time i just keep it up for when i pull my car apart to read the TPS signal when i take it apart, but with a data logger i could do the same thing. Just take a second longer to look up.

The reason i'm not getting rid of the maf translator is because of this:

So i'd like to make it worth wile.

Getting rid of is because of why?

[Gravy]

I have two things doing the same thing basically, I can just run one or the other but both is kind of overkill. It's like running two MBC's, sure it works, but only as high as the highest setting.

I was just asking cause you said, "The reason i'm not getting rid of the maf translator is because of this:" and show a pic of the translator. And I don't see anything wrong with it

[twack]

he is asking if he can do without the safc and the answer is yes. Some people like the safc on top of the maft just so that they can do a little better fine tunning. You can get by with just the maft and ive done it myself with no problems. its up to you about how anal you are on your super fine tunning

I was on just the translator but only adjusted the base settings to run 560's. I have yet to do any fine tuning with just the translator however you can and it does discribe it in the manual.

Basically you "0" out the SAFC and use the MAF translator to compinsate for whatever injectors you are using.. Then you can use the SAFC to tune from idle to WOT.

I would keep both, It will help with fine tuning and keep a steady AFR throughout the whole rpm range.

If that doesent make sense i can explain a little more, But you can only do so much with the MAF translator, I had the same combo on my last car and i had 1000cc injectors. The SAFC alone can't control that big of injectors, But if you have both you can make it work..

Hope this helps

When I started EPROM tuning, I kept my SAFC2 in for quite a while just for how nice the display is, but did end up selling it cause I figured I'd rather have a couple hundred bucks to use on other stuff. If you can get the car tuned as good without it, I'd say get rid of it if you could use the money elsewhere or need the money.

You should sell the MAF-T because I want one.

But seriously, it really comes down to how perfect of a tune you want. If you're okay with stock maps and scaling, why bother with a more sensitive setup?

[Shane@DBPerformance]

You should switch to the MAFT Pro with ignition harness, so that you can remove some ignition timing under boost. You can do a lot more with that system compared to an SAFC and regular. The stock 3S ignition timing tables are usually too aggressive for too much more boost over stock or much bigger injectors(makes it run even more timing). Or switch it to E85...
