Hub i was watching your youtube vid's and all i can say is WTF.

Cooter, get used to it. Hubs signal-to-noise ratio is extremely poor.

Mmmm. I love me some BBQ'ed ribs, baby! Gotta get my smoker cleaned up fo the season. Love the How-to HUB. Genius as always!

Yeah, COOT, I like to waste your minutes LOL... Then hear you cry you want your money back.

We need a Forum called HubTube.

MFHY you crack me up. Too bad they killed ole' Bill over there in Zombieland... loved that f'in guy! I think he was my distant uncle!?

Hubtube it is.

Here is how you follow along. I've learned a few tricks from a few guys around here. Ivan especially. This is more Ivan's working me thru a meat grinder for a number of bikes and a number of years of study. I more or less formulated a few steps that when from reading the abstract, 'timing retard eliminator' and then sent me on a quest.

If you see a gauge that swings from 0 to 15 or almost lands there? Isn't that 101 no matter how you look at it?
If you see a gauge that remains sort of steady, but gets a pounding in the beginning> Ram Effect mean anything there?
If you see a motorhome, a white van near a guard rail, a set of headlights flashing from a pass, or a set of taillights trying to show me they were going to be in my face with the bike I was on?
If you see a guy with an H in his ear? Yeah, him.
If you see a guy with his dipstick too scared to case the oil plug fandango? New York Blackout?

Let say if I am chasing this stuff as I was at one time, it has a lot to do with tuning, diagnostics, and having a basic understanding of the computer bike in general; so you are not frightened by it.

So here are a few fundamental ideas to think about. Who knows where to start? There is just too much to figure out. If I make it more of a puzzle, maybe you can put the pieces together. So lets understand 3 basic moves we can visually see and do.

Analog is your keyboard. Analog means many. It also means a step you can do, meaning, it is your input. So think of that as a sensor. Think of it as an analog signal entering the computer tower. When you keep typing out a sentence or whatever you can do with the keyboard, it sends in a lot of data. As if you were off and on at the throttle: that is an analog signal entering the computer tower.

Digital is your laptop/iphone/computer tower. Digital means single. Take the 220 ohm resistor. Take a 100 ohm resistor and build a computer, meaning, see how digital could mean single? So as the computer is receiving this analog of many sensors entering their data at that throttle angle and rpm speed, the computer knows where that key you typed was and now it is send back out as...

... Analog. So if you look at this concept, the abstract reads: the keyboard is a sensor [of many numbers of input]. The computer tower is the digital for [DFI means digital for the fuel injection speak] or how kawi simply explains their ECU is obviously digital in build, so they wank the abstract their way, me and my way. The last step is back out to analog and this is looking at the monitor. So in a way you can say your input to complete a sentence or even strike the letter you want, is your [input equals the output], right? It is like saying, 'for every action, there is an equal and opposite keystroke you be looking at the monitor.

I will now have hag take the floor and debug the hub. Hagrid is fluid in hubbish. If he grabs the abstract about how easy is it now; if you apply the simple computer concept moves I present. Hag has a knack to make it short and sweet this one down to a sentence or two. It says he's grasping the concept I pee scent I go pissing all over bg's place once again. You ass for it me being one of them.

If we recap, we can visually see our walks begin to appear. Take our analog example. If you remember me saying the tail sensor, it meant its location and was recognized as the atmospheric sensor? So imagine the tail sensor, the 760mmHg number and the position of the altitude. Lets start at zero or sea level and begin to see how the computer gathers input from various sensors.

So at sea level, this is the number that is being sent into the ECU. If we climbed a 1000 feet, the tail sensor is sending in 733mmHg, because this is now the pressure at this altitude. Again, notice how analog sends in many numbers. Look at how complex the math is and all that [to the 10th power] calculating now needed. So too is to catch the numbers game as a whole. There is that linear number change at 500ft. See how the calc has someplace to pick an assigned number burned in memory? Call this: read only memory [ROM] for it only chooses these numbers only. The lookup tables.

See how if we look at the chips made and what they can do? It has to filter out other input signals is one component in the ECU. It has to check and balance itself before the ECU sends it out kind of hardware and so on. In a way, you have the fuel piggies running their own lookup tables, and those cells that were changed are the new fuel numbers.

If you now catch the walk of the input/output rule:

Analog = Sends out a square wave the ECU recognizes.
Digital = ECU is the guy that has to match input so it sends out an output signal equal in demand.
Analog = Is the wire headed to the injector.
Digital = Captures watt? An analog signal now the piggy you hooked up to this wire.
Analog = The piggy has now sent out the analog to the new injector duty cycle.

Are we catching the 101010 process also? Are we also catching how at sea level, we are spitting out the same single number until something happens otherwise? The other various [sensors] are sending in their preset numbers so their lookup tables are math'd linear perfect, right? Or as perfect as the math gets, as in a handcuffed absolute?

Anything make sense so far? We are almost half way there to knowhere. Cross out she. Replace with Ivan

What?! I'm late for the complimentary danish!!

@Hub: you're laying it down straight and true... don't see the need for me to sum-up. But I'll give a little back history.

You guys remember the Hubcycle? All those wires? And I said he's either very smart or very dumb?

He was trying to influence, to his advantage, what the sensors were telling the ECU. He told me what he found but I'm not saying it here because he worked for it. If he wants to tell you, and in a way he did, then its his to share. He did the work.

What he and I want is for Ivan to swing by and answer some questions we have. You see, we've been knocking on a door.
