Have any of you replaced the original MAF sensor with a replacement from Granatelli, Summit, Jet or similar?

They all state improvement of airflow, power and torque.

Do they work as stated?
Any lights/codes?
Any noticeable improvements?
Value for money?
Any problems?

Besides from running dual fuel, LPG and gas, and a Volant cold air intake, my engine is stock. Original exhaust, no chip or programmer.

Appreciate any information you might have.

Greetings to you all from Norway.

 

Over the years of replacing electric parts and sensors I have come to the conclusion that I won't buy anything but OEM when it comes to these items. I buy a fair amount of aftermarket parts but have been soured on most of the electrical parts that I have bought from aftermarket companies.

I also wouldn't plan on seeing any HP or TQ increase buy just changing out MAF Sensor. You can check around but guys have spent thousands of dollars changing exhasusts, intakes, chips, ect ect ect and for the most part other than a custom tuned chip (like an SCT) you won't find much for adding any power. You can change the sound and modify all of these parts but in the end your gains will be so minimal it certainly isn't worth the bones you'll have spent to buy and install them. If you really want more power the best bang for a the buck is a gear change and the ol SC systems are pretty decent, unfortunatly, all of the SC companies that were making them for the V10 ahve ceased production.

 

Not to mention, you probably need a re-tune for any aftermarket MAF.

 

Hello Lars Petter

How did you solve the battery drain problem?

There is no way a after market MAF can do the things they claim all by itself

They electronic gizmo is identical electrically as the factory part...so much so that there is no recalibration necessary...the computer can compensate for a wide range of these after market sensors...the area on a Ford motor that senses the intake volume and temp is larger then necessary for the max flow of the motor at WOT... there are NO parts that can be added in this area that will increase power or torque

It is a fact that a MAF can get weaker over time from corrosion and dirt, and not be as responsive...installing a new one can increase motor effeciency...older MAF sensors can be electrically cleaned and have dramatic effect in their response time and accuracy

If the aftermarket product is cheaper then the factory unit go that way...

 

Fred and Lars ,As you may know the game being played with aftermarket Mafs is
a change in the resistance of the IAT(intake air temp) sensor.
Because this is built into the maf on our trucks as one piece.
By them changing the resistance they change timing advance overall.
a person can do the same thing with a resistor inline with the IAT feedback to the PCM.
Don't waste your $

As stated before reliabilty and cost should out way any benifits gained.

Just my 2 cents
Rich

 

I couldn't agree more.

The only difference certain things will make is the pedal "feel" will change. You might get more power at slightly less throttle, but overall MAX power will not change.

The exhaust crossover is another story.

 

Hey Art...a few years back one of those Fancy aluminum pipes they sell to replace the factory molded plastic/Rubber one was being advertised by the picture of the pipe on a Flow bench and they claiming the the special mandrel bent 4.5" diameter pipe would flow over 2760CFM...too funny...you ever see the secondary bores of a carb that flows 1250 CFM??? http://www.holley.com/0-80532-1.asp the 4.5" inches will flow enough to fill two of these dominator's and the 415 Cubic inch motor will never get any fuel sucked through them for lack of any venturi vacuum

 

Anyone have a picture of the location for the MAF on a 99 F-250 V-10? I want to clean mine and just need a picture to help with it,, Thanks, Tim

 

No picture but it is the very first electrical gadget in the intake pipe after your air filter

I do not recommend any mechanical cleaning method... get a can of electrical contact cleaner... there are folks who do use a "Q" tip and if you are VERY VERY gentle you can get away with this...but that teeny tiny heated wire is very delicate and once it is broken you get to buy a new MAF

 

Hi guys,

Thanks for your reply. The reason I am asking, is because I am about to clean my MAF. If I happen do destroy it while cleaning, I would have to replace it. Nice to know if the replacement is worth the money. From what I have understood, I better do my cleaning carefully, and stick with the original MAF.

The instructions I have read here in the forums says:
Disconnect electrical connector, remove MAF from intake assembly, spray MAF with alcohol based electronic cleaner, let to dry, reassemble.

Fred: I solved the battery problem. It was a relay in my LPG system that was connected incorrectly, causing a constant 2 amp drain. During the summer, using the car every day, this caused a dead battery once a month or so, but when the winther arrived, this happened almost twice a week. Very frustrating. So before I found the reason for the drain, I had to hook up a charger every night, just to keep my EX running until I arrived home again in the evening. So now I am ready for all the winther there is.

Thanks again for responding. Hope you all have had a nice christmas, and I wish you all a happy new year.

Drive safely. I have been told that if you see your own taillights in front of you, it´s time to slow down.

 

The earlier MAFs like in GM's and Fords back in the late 80's/early-90's were pretty delicate.

The "new" style we have in the SD's (and in my 96/97 4.6's) is a very thick piece of wire, with a glass cylinder with the "fine wire" wrapped around it. And then coated in something else, looks like glass.

Still delicate, but not all that bad to clean. In some ways, I'd think the blast from a can of electrical cleaner would be rougher than a slight touch with a Q-tip.

Lars, keep in touch!

 

Oh, and Lars, if you ever need a part that's not TOO heavy, and you can find it cheap enough here in the states, I or someone else (maybe) would be willing to ship one over for you just for the shipping charges. I know how hard it is to get US companies to ship stuff out of the country.

Like a MAF...

 

Krewat, thanks for your offer. That is really generous. I will keep that in mind.

As you surely understand, shipping charges is the big issue for me when I order parts from US. I have purchased quite a few items on ebay, like 1-piece headlights and taillights. Sometimes the shipping charges is twice as much as the item price.

At the moment I am looking for 2 specific items.

First, I would like to buy a Street Scene speed grille insert in stainless steel. All the places I have searched states that this item is no longer produced by the factory. But I belive that some warehouse somewhere must have a leftover item. But I have no luck in my search.

Second, I am looking for a pair of gray leather armrests for my front seats. The previous owner of my Ex installed a seat in the middle of the front row, but I want to change it back to separate seats again. I have the senter console, but the the armrests are missing. The previous owner do not know where to find them. So that leaves me searching for complete armrests. Buying a set of new ones from my local dealer will cost me nearly USD 900. So I am basicly looking for a pair of used armrests for a reasonable price.

I know that this is not small items, but I would really appreciate any help in just finding the items. When it comes to shipping charges, I am used to high quotes, but it surely would be nice to keep it down.

Appreciate any help, and information to get me further.

Thanks again.

 

Shipping by USPS usually keeps the cost down - the "broker's fee" for customs is outrageous with UPS or others.

If you can find the part, and get it to me, I'll be glad to ship it to you. I do this sort of stuff all the time with what I sell on eBay.

The grill insert would be absolutely impossible for me to ship. Well, not impossible, but certainly over-the-top. The armrests sound feasible

If you can find them...
