MAF tuning

[aldive]

Has anyone who uses the Pro M MAF used the MAF Tuner?

Thoughts and opinions sought ....

Thanks ....

Haven't tried it. I wonder if this is an updated version of the old "tuner" that had controls on top of the MAF?

 

[blk mk8]

that is not a good way to tune your car. messing with the maff the wrong way affects a lot of other stuff on your truck and cause problems.

Ultra Tuning

aldive, I agree with blk mk8.

Are you looking for final fine tuning? I assume so, and may I suggest look at finding the highest quality MAF, O2 sensors, fuel injectors, and dyno tuning of the PCM(chip).

Those parts can be as much as double for the best available, and may gain you a slight amount in efficiency. Good luck,

Sorry, you assume wrong; I was simply asking about the product. But thanks for your suggestions anyway.

Okay, I based that on your many posts which lead to higher efficiency. LOL,

But how can do you better than the alleged 30 mpg? I think he needs to start considering fabbing parts from Balsa wood and titanium to do better than he already has.

I don't care for any Products from Pro-M. One for their poor quality and two for the way they " Con-artistested" us last year at the V6 Ford Challenge in Milan.

Another reason is just as BlkMr8 said any product that messes with the mass air readings in any other way then adjusting them in the PCM programming is nothing but a bad patch. This isn't a good way to do things as your mass air readings adjust your load readings and this can in turn affect the entire spark and fuel curve.

Doug, thanks for your input, it is always welcomed.

Doesn't the ebay $2 chip do almost the same thing? In essence fooling your computer/MAF?

From what I read, it looks like this fools the computer by increasing voltage from the MAF to supply more/less fuel at a given reading from the MAF. I dunno about this one. But then again, I'm no engine tuner.

 

[tweakedlogic]

no that's just a resistor that makes the computer think the air in your intake is colder than it is.
On my RX7 I cracked open the MAF and re-calibrated it so it would advance the timing and throw a bit more fuel. I could feel a juge difference in how hard it pulled. But that is a rotary engine and already hopped up and modded. I don't know what it would do to the X

So aftermarket MAFs in general shouldn't be used? Pro-M is the same thing as Granatelli.

The assumption behind products like this is that Ford's engineers missed something that we won't. Not a good bet.

E.g., one can always richen the fuel/air mix a bit for more horses. But fuel economy drops and the car may not pass emissions inspection.

IMO, the improvements we tinkerers can make are generally the kind that Ford rules out for cost reasons. We might think nothing of polishing an intake for better throttle response. Ford wouldn't do it because they couldn't recoup the expense in the sale price.

 

[CDW6212R]

Sorry msmith65, but no!

Ford leans toward settings which help the engine survive longer, run cooler, start better(whatever it takes to sell it, and last through warrantee).

A lot of the improvements that we can make are about optimizing A/F ratio for more power, etc. Ford builds in settings that will survive in various climates, and abuses by owners. These are general terms, but they apply to many aspects of a Ford vehicle.

Sorry, but you are mistaken.

 

[spindlecone]

Sorry, but you are mistaken.

Even PRO-M states that the OEM mas is one of the finest made, with that being said, the main point of an aftermarket MAS such as the Pro-m is more airflow do to it's larger size ( my case about 30% more).
On a flow bench the Pro-M is calibrated to your injector size, I belive at 7 differant points.
The only way to actually see if your MAS is properly calibrated is to get Dynoed and have your A/F ratios measured, in my case the A/F ratio is 12.8 on average.
for my mods and the HP and TQ that I am getting, 12.8 is about right, my MPG has not been effected.
I think the calibrator would be a great tool for an actual tuner, with a Dyno, for the garage mechanic it may be a waste of money.
Once the Mas is set for the mods you have , your done.

MAF

 

[huskyfan23]

MAF = Mass Air Flow
MAS = Mass Air or Airflow Sensor

MAS does make more sense.

I had a Pro-M MAF and I noticed a slight increase in performance, but it was all in my head. I pulled it off, reset the ECM and put my stock unit in. Same power. I say if you're supercharged get a new MAF, other than that it's not worth it.

 

[CDW6212R]

Yes, it is a MAF sensor. I use "MAF" because everybody that I have dealt with at Ford, or elsewhere, does also. No biggie, later.

How about MAFS, sort of hard to say
