EEE 101 The Skeleton Of The EFI

[Jersey Big Mike]

And a slight correction.
The MAP will read max at 0inHg and voltage will drop as vacuum increase. I hadn;t looked and was speaking theorically but the usage to the microcontroller is the same, math just is different if those levels are inverted.

You know, I am standing right beside you with a switch being a VOES as designed.
I am standing beside you and agree MAP is against 14.7.
I am standing next to you and agree, let's take the next sensor and throw a heat strip across it and the mass of flow over that glowing wire is being cooled by the flow of the air and the differential is shown.

I agree there is no VOES in EFI.
I agree there is more telemetry as it evolves.
I agree the specific device can be designed as a switch, can be Vac, or a glow ribbon.

I'd be a fool if I did not see each as a different function of that device.
I am just wondering why there is an agreement that an analog signal goes up each wire, as many different devices can do the same thing.

Can I get you to agree on that? Because that is not an argument per say, I want to understand that no matter the device, it is to send analog, yes or no?

Well we aren't slicing into billions

Correct. I used the increments meaning as a blue, but a different blue is all of .001. The next color is .002... all playing with an analog signal in the abstract of so many analogies being almost as endless thinking of the next non-real working device. But it does have to follow natures law of the handcuff of 'it only works one way' and off I go.

we are slicing the range typically on a microcontroller to 1024 levels

Again, I in the abstract will get myself up that wire any switch way without a number said, and how I see analog in micro movements. Even though we know it's math'd in binary is the signal made, is collect the slices you get one number. That's just idle.

I'm saying the slice is so linear in the moves, you can't feel it like you said it's so linear smooth is the action.

But that doesn't mean it isn't happening internally.

I'm am seeing exactly what you are saying. You sat down, shown formula, have the head for numbers, and understand it well. I am not at that level. Were you around 15 years ago when I went into culture shock and left the industry in '99, and never caught that shop manual to un-shock me some?

So no matter how you slice it, the concept of any switch or sensor, it is the "many out" of that device and "up the wire" to the processor.

Can we agree on that at least?

 

[Sven]

The MAP will read max at 0inHg and voltage will drop as vacuum increase.

The abstract means, there is an opposite that is equal and this action is the same as an 02 does is that opposite switching on the magnetic sniff of a chemical. But the theory is for every action... yada-yada in the electronic handcuffing is back to nature to see it all work w/out a number.

I hadn;t looked and was speaking theorically but.. those levels are inverted.

Got ya exercising your walk?

 

[Sven]

So you bought a new set of wheels. No. I bought chrome rims.
So you bought new rubber for the car. No, I bought tires.
So you analog for exercise. No. I walk in a circle.
So you digit'da wall switch. No. I turned off the light fandango.

Yes we are on the same page for all of this.

Again my arguement was and is the incorrect use of the term VOES.

 

[Sven]

And my argument is that they all do one specific function that you have to agree more or less. It's a ford, but still a car.

MAF = Multi Analog Feeder
MAS =Manifold Analog Sender
VOES = Variable Oscillating Electronic Signals

And you can't deny they do exactly as designed for one specific function. The Skeleton = Analog.

Yes they are related to Vacuum/Air intake into engine.
But the Correct acronyms are

MAF = Mass Air Flow
MAP = Manifold Absolute Pressure
VOES = Vacuum Operated Electronic Switch

VOES has 2 settings below x pressure and above x pressure (and is not used for EFI)

MAP reads pressure - reads and produces variable readings across range

MAF reads pressure and temperature and calculates air density -- reads and produces variable reading across range.
