MAF Translater used by itself for tuning...

[nitrofed7]

Is it possible to use the maf t alone without any driveablity problems.
I know several people who have VPC which is similar to how the MAF T works and the car runs great when at WOT but runs really crappy bottom end at low rpms. Since the MAF can only set one fuel setting throughout the entire curve it would only run good either up top or down low depending on how you set it. It would run good up top but be to rich bottom end, or to lean up top and good bottom end. ALSO what happens when you change boost then you have to retune all over again becuase its not boost senstive. I DONT know much about this so any help at all on understanging how this works would be great. I know you could add a afc but then your just complicating things and spending more money and it would be better then to just get a stand alone because its the same amount of money anyway once you start adding things. thanks someone plz enlighten me on how this is a cheap and affordable without any drivablity problems. thanks.

First of all, you do not have to re-tune when youy change the boost. The hotwire-style maf, the kind used by the MAFT, is the most accurate way to read air that I know of, and doesn't have any problem coping with changes like boost.

You should be able to get a car running fairly well with a MAFT and decent sized injectors (660 cc/min and under).

Also, I know people who have run fine with just a VPC. The VPC has an idle adjustment knob, and an adjustment knob for WOT, so I don't see the huge probledm there either.....

I don't know how you think a standalone costs as much as a SAFC and a MAFT. A MAFT and a SAFC together are like 500 bucks, that's like half the price of a standalone.

I'm running with just the MAFT at the moment (had to strip the SAFC so I can park the car on the street), no real problems.

when you were running the MAFT and the SAFC together (i'm assuming you were) how did you set it up? Were you just using the MAFT to set a baseline fuel map, and fine-tuning with the SAFC?

One of my friends has a mirage hatch with a 4g63 and has only VPC.
dont get me wrong the car runs great up top but down low its horrible way to rich. And it was tuned with a wideband.. I know you can lean it out a little and make it run better bottom end but then you are losing fuel up top. So i dont know how safe that is.

And Kpt4321. maft and afc are about $600. You could easily get a decent E6k for like 850 or so. and for $200 more i would much rather have a standalone.

then go for the standalone, wut more are u asking? a standalone is better than a piggyback so go for it

 

[DrZiplok]

I was using a 5-knob SAFC so that I could tune while driving, then I'd move the changes that I made across to the MAFT and re-zero the SAFC.

For light to moderately modded cars, the MAFT seems to do a very good job.

I thought the MAFT did do more than one fuel setting. Doesn't it do idle, low, med and high??

I believe they are indeed Base (global setting) Idle, Cruise (low), Medium, High

Nitrofed, you're smoking last week's bannana peels.

If you think that tuning a Haltech setup has any resemblance to tuning a piggyback like the MAFT, you need to go stand in line for that new movie again.

You can do a proper MAFT install (translator, MAF, filter, intake pipe) for under $400, and tune it in an evening.

Conversely, setting up with a Haltech will cost you a lot more than your claimed $850, and you'll be lucky to get the car idling by the end of the weekend (unless you're already intimately familiar with it).

Not a suitable response to be bringing to this thread.

Yup, you are exactly right. All I use is the MAF translator and a pocketlogger. No knock at all and the car runs pretty good anywhere in the rpm range.

drziplok. First off I never stated that there even was a resemblance between MAFT and HALTECH... MY agrument was why even spend 400 on a MAFT when it only has BASE settings which means the car really isnt being tuned at all, If you want it to run good in one area you have to sacriface it running good in another area.
And I see used e6k's from 700-900 all the time on forums and partstrader. so what are you talking about, new is 1150.

and btw DRZIPLOK, i Have owned a FD3S for 4 years now that runs 11.79 on stock twins with an E6K so i think i would be a little fimilar with it. especially getting it to idle since any base map would get it to run.

I have a 90 gsx as my daily driver, my question is how good does it feel with the Maft or would you even call that tuning.. Am I just wasting my 400 which would be much more worth spending toward a stand alone. Iam not to fimilar with the translator, i just want to know how the car feels with just the MAFT.

Also to even get anywhere remotely close to fine tuning the car you would have to datalogg and add a AFC which would total spending over 700 for everything. SO $700 to get all of those things which only complicates things anway and is nowhere near the quality of a standalone why not just by a haltech. they say this stuff is much cheaper to tune then buying a standalone but in the end its the same and the tuning capabilities is garbage.

Nitrofed, again, it does more than base settings. See above.
