Computers Today

Could you tune your car’s Electronic Ignition? The girls in Elgin Library could.

Warning: I say below that I could tune a car engine now, but remember I spent twelve years learning the mechanics, and even more using computers. You probably have not learned both, and therefore you should not make changes you do not understand. Go to a qualified tuner. (Have they ever used a computer, and put two and two together? Probably not. In fact almost definitely not)

I spoke to a mechanic a few days ago, who has just retired, after nearly fifty years in the trade, and he told me he still didn’t know a thing about electronic ignition. Neither did I until yesterday. Now I find I not only know it all, but I could build it. Any competent computer user could. He says he “knows nothing about computers.” He’ll kick himself if he decides to learn them in his retirement.

An ‘Electronically Controlled Unit’ (E.C.U.) is what runs your modern vehicle. The term is very misleading. In fact it is not. It is a program on a memory chip in the E.C.U., just like a U.S.B. pen, which the unit accesses, and uses to run the system. This misconception has held back western industry for decades. The Chinese understand the difference, and utilise the computer for all their industry. It is very, very simple to use. It requires a laptop, a software program, and a unit to read and translate the information into robotic, or electronic performance. It is also the same technology used to make music with a sequencer, drive spot welders to build cars, sew dresses or trousers, drive lathes and a million other uses. There is no limit to what it can do. It is literally infinite. It will someday be thought controlled, as in heaven. The software only needs two elements. Sensors to gather information, and output to mechanical parts to make the changes. A program only needs numbers. Plus or minus. If it applies to left or right, for example and zero is centre. Plus is right. Minus is left. I was reading on the internet yesterday that a car can have a setting for every position of the accelerator, but if you use an excel sheet, and new ignition E.C.U.’s do, you can simply write the increment or decrement into a cell, and let the program use that. Changing with every revolution change. Let the throttle off = zero, and full throttle = 100, and give all numbers between a separate program value, you could change the fuel mixture for every setting, with care and within reason. Race cars are set up this way. I’d not recommend it for road vehicles. Two settings. Idle and cruising are all you’ll ever need.

In 1971 the Chrysler company created the first E.C.U., (According to the internet) and until recently it has needed a dedicated computer to tune one. Now you can plug in a laptop with a U.S.B. lead, open the program, make the changes, save them, close it out and the changes will take effect. The same as any software, because that is all it is. (Knowing this now, I find that this unit is in fact greatly underused. It could make your tea on the road at the touch of a button, and do a million other things as well) It would be brilliant for Willie Sinclair, because he could keep a list of all the pubs in the U.K. on it connected to his SAT NAV. He navigates by pubs. Left at the Bonnie Earl. Down by the Golden Pheasant and it’s near The Ionic ,,,,,,,,.

Some links below to help you understand how simple it is. Beginning with the U.S.B. use, and working backwards to the older computers before windows was invented. You could write software for a laptop for older systems as well, but I believe it is easier to fit a modern chip they say. Don’t go thinking they can’t do what the older ones could. They can, and much, much more. It’s interesting also that if you make changes to improve your old engine. Such as using Redex, you will have to retune. Same as if parts wear. It works both ways. I met a guy who had that problem.

U.S.B. see programmable ECUs. The same page and place for the ‘spreadsheet’ program explanation. If you don’t understand that then you can’t use a computer. See also History on the same page for older systems that required dedicated computers. Monstrous things that take up half a garage workshop, but can’t do half what a laptop can do.

E.C.U. These units vary in size according to manufacturer. A laptop would do exactly the same job, but would take up too much room under the bonnet, and be a bit of an overkill. A Waste of a laptop. You’d use laptops for industry though. Much more versatile.

TECH1 TECH2 are older examples still in use. These are exactly the same, but came before Microsoft, or even before computers as you know them. Is this where Bill Gates got the idea for his ‘Microsoft  Windows?’ I suspect it is. Remember the Chinese have been using this very simple technology for decades. It does not cost jobs. It creates them. I’d bypass manufacture, (They do it all) and go for leisure, but that’s just me? And I’d hang Elton John and Co’ for hiding this technology and it’s use.

Right teenagers I have to tell you, because your parents are thick. (I don’t think there is even one overpaid person with Moray Council, for example, who could do this. They could do one or the other, but couldn’t put it together. Neither could the Moray College, and they teach CAD without any understanding of it)

Who uses computer CAD properly? Everyone except the British. How simple is it? Very. I shall explain.

This is an Australian based boat builder which uses CAD properly. The first boat is built, probably using Lofting, but maybe using computing. Lofting is considered the better way. Every plate when it is finalized becomes a computer file, which can be recut by computer as many times as required. TorchMate.* For ten boats. Fifty. Whatever. (*Or see it on the Bruce Roberts site)

Cars are built exactly the same way. Every part has a part number. Every part becomes a computer file with number. Every part can be recut at will. Like a jigsaw puzzle it can be made over and over again, but let the computer do it, for it does it with no effort. Fridges, freezers, cookers, anything. They all start as flat sheets of steel. What making in a fridge / freezer? Very little. Or even a TV or Computer.

How many of your dads could build a car or boat this way? Blacksmiths with spanners could make one now and again the hard way, like the Buckie boat yards scraped together a mish mash boat at a push. But mass produce? Not a hope. They thought the computers did it all without skills. Missed the point. How many of your dad’s have these skills or could even understand this? If you want to work, this is what you must learn and improve on. Wood, or metal, or any material.
