MAF removel question
Does Anyone Know If You Can Take Off The Maf With Out A Computer If Yes Please Let Me Know

MAF sensor?
|
Ignoring the incorrect terminology, the answer is no. What exactly do you think it's there for?

considering out AFM's don't measure air mass directly, I could hardly call them a "mass air flow" sensor.

The EFI system is technically a MAF system, so the term used is correct in generic terms...

Yes you can, but you need the now discontinued HKS VPC (or similar unit) to remove it. If you can find a VPC it will set you back around $300 US dollars. Not to far off a megasquirt are ya? :)

thanks heard it could be done

They measure air velocity and temp and the ECU calculates mass airflow from those inputs. But I know you know all this... Yes you can, but you need the now discontinued HKS VPC (or similar unit) to remove it |
I've NEVER had to use a computer to remove a afm. So the correct answer is that, yes, you can remove the afm without a computer. Just use you fingers to remove the plug and a socket to remove the bolts. .......Not humor.
It's the question that was the joke. Any other tough questions? |

I really hate Wikipedia, but it actually does have a somwhat correct definition in this case: http://en.wikipedia.org/wiki/Mass_airflow_sensor Feel free to look it up in your favorite engineering book. You may learn something. ;)

Ah, but we're not talking about a "system", only the airflow meter. In common industry terminology, MAF (mass airflow) sensor refers to a hot-wire type airflow meter, not a moving-vane type like FC's have. Moving vane AFM's are not MAF sensors because they don't directly measure mass airflow. They measure air velocity and temp and the ECU calculates mass airflow from those inputs. But I know you know all this... ;)

Wouldn't mass density effect the "cooling" of the hot wire too? In which case it doesn't only measure airflow velocity.

Ironically, the word "terminology" is the wrong word in the sentence. "Terminology" is the study of terms. You would be stating that he would be ignoring the incorrect study of terms. The correct word is simply, "term". |
Actually, a couple of dictionary definitions of terminology are "the body of terms used with a particular technical application in a subject of study, theory, profession, etc." and "the system of terms belonging or peculiar to a science, art, or specialized subject; nomenclature". Your meaning is also correct but rarely used.

Funny then how the term "MAF" wasn't used until the hot-wire AFM came along. Who really cares if you can make an argument that it's a "type of MAF senseor", that's not what they've ever actually been called.

My point with this, as well as my original point with the MAF term, is that some things are not necessarily incorrect just because they seem foreign to one's lexicon. |

Funny how the thermal anemometer (aka hot-wire anemometer or HWA) wasn't called a "MAF" until the automotive companies and internet crowd got wind of it.

NZ, yes I did misread your post, sorry. I seem to be doing that a lot lately.
Evil, why argue over this? The sensors measure exactly what they are called. Air Flow meter, measures airflow velocity where as Mass Air Flow sensors will measure the mass density or air. Im sure you could call the "thing" known as a AFM, a potentiometer right?

Vane meter sensor - The vane measures air volume, not mass, however by measuring the air temperature and pressure to determine air density. I also suppose putting both into a category of MAF sensors is incorrect as well since they don't measure Mass Air Flow directly, its up to the ECU to determin that. So why not just stick with airflow meter and Mass air sensor or something of the sort :) Gez, and this talk about what word to use, SHUT UP you cry babies :crying: :crying: |

FYI the three most common EFI system types are: 1. Mass Air Flow 2. Speed Density 3. Alpha-N I think you would agree that the AFM and MAF hot-wire sensors both apply to #1. (If those three terms are not familiar to you, feel free to research them, and you will see what I am talking about.)

You guys would argue about dogshit, no?
