Diablo MAFia Correcting more misinformation, Let me post the MISINFORMATION first and then i will cover some facts

Its stuff like this that hurts new Focus products you would think that people IF they didnt know what they were talking about would at least say nothing

" BUR_ZX3 [FJ] Sorry no. Do NOT go with the MAFia. All it is, effectively, is a variable resistor that changes how much voltage is allowed through. Your metering will be all off. You don't want to change the voltage, you want to increase the range of measurement.
[:)][:)][:)][:)][:)][:)]*Lets start here I have tested about 30 of these now and NEVER seen one off the first order i got was 5 and i tested all 5 of them on the same car and everyone was EXACTLY the same as to where and how the voltage was in line with the other 4 MAFia not even a 1% Diff
Please people dont listed to people like this , this guy has never tuned a car in his life and ill bet he has never bought a MAFia let alone done any testing with one

Now to FACTS the MAF can only work in a 0 to 5 volt range any meter OBDII that you use will be the same on that fact BUR_ZX3 sais "You don't want to change the voltage" with the MAFia used you DO NOT change the voltage it is still a o to 5 volt. Then he sais " you want to increase the range of measurement." Thats correct and it is EXACTLY what the MAFia does


"BUR_ZX3 [FJ] Any tuning option worthwhile should be plug and play with any Ford OBDII MAFS. For boost, I really think the best options are the Mustang GT, the Lighning 80mm and 90mm if you need it that wide. Those cars make far more horsepower and move far more air than a focus will... so you'll be perfectly safe in one."
[:)][:)][:)][:)][:)][:)]*The MAFia is exactly that a "plug and play" makes your Focus MAF do EXACTLY the same results as using a GT MAF . But with the option of using a smaller MAF tube for ease of install and looks as well as better idle , tip in response the 80mm and 90mm is a little big for a 2.0 engine and the readings at idle are a little low, they can be used but that is a choise for each to make

Then we get a shop that people actually listen to say
FocusSportVP The MAFia is a waste of time and money. If you're going to do it, do it right and step up to a MAF that can handle the power output of the given application

The MAFia is as right as it gets, it is affordable , it works , its plug and play , it adjusts to where your not using a LARGE MAF and only using 40% of it because it has to much range ,its easy to set , it looks good , you will never need to change meters again , it makes your stock MAF electronics more powerfull because of all the options in range and never having to recal or look for another MAF later , it works with ANY software, no dealing with bulky 4 bolt flanges and adaptors because you can make or buy your own tubes , its accurate

I just wish all the misinformation about stuff from Co that should know what there talking about would stop. If you dont like the product at least say why, I dont like SC but i say what the down falls are to them and why

I welcome from both the reasoning behind not using them and from randy how many he has tested and what was the problem with the ones he tested

The Diablo MAFia is a very good tool and it works well, I have tested it and have not found any issues or problems why there not safe or accurate to be used to over 700HP

Tom

And that sir is while I will be using one in the near future.

Well, I got to hand it to you Tom. I definately learned about this product, and should I ever need it, I wouldn't hesitate to benefit from its' purchase. As such,
it does us all a good service to clarify erroneous statements. Your stepping up on this issue is commendable. Thanks!

You hit that nail on the head Tom. We use these and they work very well. I have done several Mustangs and Cobras with over 500+ whp and they work fine.

So how does it work?

Also, I can buy a brand new Mustang GT MAF sensor for about $120 shipped. How much is the MAFia?

OK, maybe I'm confused. You state that they use 0-5 volts but then Diablosport states that it extends the voltage limits.

The MAF.ia. (not MAFia - it stands for MAF Interface Adapter) is a device that works with the factory Ford MAF sensor to extend voltage limits using multiple settings, for 400 to 825+ RWHP, supercharged or high horsepower naturally aspirated Ford applications.

This has me believe that they go beyond 5 volts since they say extend.

Yes, No ?

Also, what about the IAT sensor on the stock MAF connector.
Is that signal passed through the MAFia cable ?

dunno about the IAT, but i'm pretty sure the range is still 0-5V (just corresponds to different air flow values) since your ecu wouldn't like that signal to go higher...

petik as i said the GT MAF will work the MAFia is 149.00 and will mean as you go up in boost you wont be changing MAF electronics and as you have lower boost you MAF signal will be better because you using the proper range for what your doing

I dont like 80 and 90MM MAF housings you dont get as good a signal with the larger units as you would with a 3 inch tube or a 70MM. I also dont like the 4 bolt flanges there bulky and the hoses to adapt them are also costly where as making your self or buying a 3inch tube is much easier to use

The MAFia is as good as your stock electronics are it still has a 0 to 5 volt range but gives you more range for boost within that 0 to 5 volt limit

Yes the IAT carries through the MAF wiring

Tom

The misinformation just keeps coming. Here is more wisdon from BUR_ZX3

"But the problem is, when people return to the adaptive learning.
So the rule of thumb: If you're OK without adaptive... then MAFia is OK for you. If you want your PCM to still have adaptive... then you might look elsewhere
[:)][:)][:)][:)][:)][:)]*Where did this rule come from, who said this or has proven this to be true,I can prove it to be more misinformation

And it is NOT an external means of changing the transfer function. Its a external manipulation of the voltage that the MAFS is sending.
[:)][:)][:)][:)][:)][:)]*Guys please how can it NOT be changing the MTF if it is changing the voltage the ECU is seeing , Do you guys see how full of BS this guy is more misinformation from some one that has never even installed one or tuned with one


I fail to see how this is any different thank those ebay resistor mods that we see all the time.
[:)][:)][:)][:)][:)][:)]*Beleive me i can see how you cannot see the difference. With all your vast knowledge of how the MAF works this shocks me

Acutally I do see how it could possibly work... turning off the adaptive learning in the PCM. Because I think the PCM would realize that its not getting its full range of voltage, and start to compensate.
[:)][:)][:)][:)][:)][:)]*Not getting its full range of voltage. First the MAFia`s 7 settings can get its full range of voltage as well or better than sticking a 90mm MAF on and it never seening 4 volts and only working in the lower range all the time 2nd) there is NOTHING in the adaptive learning to make up for or change "getting its full range of voltage, and start to compensate."

It amazes me people listen to guys like these listed with all the misinformation that allways comes out of there mouths and people flock for tuning and information and they dont even know or understand how things work

Tom

WooWoo good job

"the maf.ia does seem to work linearly. it has 8 settings, 0-7, which allow various levels of manipulation, translating to various peak maf counts/voltages or various peak power levels. this is good in that you can set the maf.ia for lowest peak power levels that you dont expect to exceed and not have to sacrifice as much low flow resolution."

This is exactly what it does and how it works ,The "7" setting is just a slight 5% and does not do much for range you have 5 working settings that do adjust the range of the meter

Tom

Tom, thanks for the explanation, can you plz elaborate more on the different settings available?

Wow thanks Tom.... Could this help fix my not so nice idle?

It turns out that with the Focus stock MAF electronics that the numbers go like this

Setting 1 is +/- %5 fuel Dont remember for sure + or -
Setting 2 is for 20lb +/- Injectors
Setting 3 is for 30lb +/- Injectors
Setting 4 is for 40lb +/- Injectors
Setting 5 is for 50lb +/- Injectors
Setting 6 is for 60lb +/- Injectors
Setting 7 is +/- 5% Fuel it is the oposit of setting 1

The +/- meaning 4=42`s , 5=55`s 6 i have had work very well with 72`s and moderate boost

The MAFia has a built in light to let you know that is is on and working as well as to ket you know when you hit max voltage at that setting. I know most doing there tuning would already know this by the scan tool but still a good feature

If your going to do it and do it right a 80mm or 90mm you give up soooooo much resolution at idle and low part throttle. I have found that a 3 inch tube DIY or bought the Focus MAF electronics and the Diablo MAFia is the best overall combination for the Focus to date that is why i started making my own MAF housings and stopped buying Recal electronics

Any good tuner would know this already tho and wouldnt be so quick to make foolish statements that he cant back up

Tom

How much hp will the mafia support with stock svtf meter?

I have seen the MAFia do 340 HP to the wheels with it in the 5 setting and the SVT Electronics and still have some room left so im guessing a good 450 to 500HP on the 6 setting

Doesn't the MAFia still do linear translation from the full range back down to 0-5V range (V=I*R)? That would mean you still sacrifice the low rpm/idle resolution, wouldn't it?

No not if you use something like a 3 inch tube and say setting 3 or 4 for 42lb injectors this willl then depend on boost and how much air you move low boost setting 3 may work best mid to high boost setting 4, this is what makes the MAFia so nice

Poor resolution will come from to large a tube not the MAFia and anything over a 70MM or 3 inch tube is to big and if you not shooting for 280 to 300 i would do even a smaller hole

It would still be interesting why FS randy does not like about the Diablo MAF ia

Tom

Tom, how does the maf'ia relate to load values? do you have to compensate for the maf'ia in the load tables when tuning? or does it translate load normaly? if my goal is 200hp could i use the maf'ia with my stock mafs and housing?

You will have no issues with the load values. To make 200 yes the stock MAF and electronics with the MAFia will work ok but anything more needs a bigger tube to a 3 inch

Tom

So I have an SVTF MAFS w/ a IAT relocation and a (kinda crappy, imho) tune. It I'd buy the MAFia and take it with me when I get a retune, would I need to change anything?

Thats a hard question to answer with out knowing more

If your asking if you take a MAFia with you to the tuner plug it in and set it to a (?) setting would anything more have to be added or changed the answer is no and very little if anything in the tune would have to be changed either

Thats what makes this unit so sweet to use

Tom

Yes, that's what I was getting at. Basically, if I get a retune, THEN get this unit, is it still considered "plug and play," or does this need to be tuned into the complete setup.

Also, does it matter that the IAT is relocated? Do I need to undo the relocation?

I would do it before you get it tuned this unit does need to be tuned

No it does not matter that the IAT is relocated you will be fine there

Tom

QUOTE "FocusSportVP Re: MAFS - which one to go with? "

"I stated my professional opinion on a product. "

YOU DID ! where i must not be able to read that in there or missed it all i saw was this BS comment " The MAFia is a waste of time and money"

I would kind of like to know your "professional opinion " of why you say that
