It has nothing to do with the CPU. The reason ECMs are specific to cars is that different cars have different sensors and actuators that require different control hardware and signals. How many fuel injector lines should there be? What kind of drivers do they need? Turbo boost controls? How many knock sensors? Even open source ECMs are built to suit certain applications. One size fits all doesn't work unless everything goes on a network. I don't think fuel injectors and temperature sensors need network addresses and I certainly wouldn't want to pay the dealer to configure them for me.
You're pissed off that you had to pay $700 for something that should have been under $200. Toyota screwed you. What makes you think they won't charge $500 to program an ECM you get from someone else? The ECM for my 1987 GM is specific to the particular model, but I can get a replacement for $100 and transfer the data by plugging in a couple PROMs.
I agree that many modules in automobiles could and should be standardized for plug compatibility but the ECM is not one of them.
The ECM has to interface with the rest of the car. They have over 100 pins on their connectors. It would be unreasonable to expect that every car be built according to that pinout. $15 is a bogus number anyway. I'd put retail value at about 10x.
The $700 ECM Toyota doesn't surprise me. You could probably call AutoZone and get a certified one for a 93 chevy for about 1/3 the price. The Chevy is proprietary also.
GM/Toyota can't stop 3rd parties from selling refurbed/repurposed hardware but they are doing their best to prevent it from being usable without paying big money to the dealer. e.g. some new ECMs won't run unless the dealer codes them to another module in the dashboard. It's a theft prevention measure but it's also a way for them to take money from unfortunate owners.
And bugs get splattered by windshields except at MS where they get sold as features. Bill Gates got to be the richest man in the world by selling poison.
Fuck him, fuck everyone who works for him and fuck everyone who defends him.
I used to love their products and by extension the company that made them.
My hatred for them started about twenty years ago when I learned a couple facts about them. For one, it's absurdly expensive to repair their stuff. It shouldn't be but it is. You bought their crap, now you'll pay. They, along with Matsushita and others destroyed the US consumer electronics industry by illegally dumping their goods in our country.
Throw in their willingness to ignore their own CDDA standards and make bogus music disks. And there's a rootkit? Are you kidding me? Contribute heavily to the RIAA and then go steal IP like this? Nice guys, huh? Yeah, I'll do business with them... when hell freezes over.
I recognize the Chairman of iQor as a past president of First USA Bank.
Those bastards were unrelenting in giving my info to telemarketers selling Field and Stream magazine and other stuff I didn't want.
I remember the name because I tracked down his office phone number and called him personally every time I got an unsolicited message. The calls went on for over a year because they had spread my info so far and wide.
Fuck you Randy Christofferson, fuck First USA Bank, and fuck iQor.
I suspect the OP understands that aero drag isn't linearly related to speed. Aerodynamics haven't stopped IC cars from improving by more than 13 MPH. This record is notable mostly because the old record is so very old.
BTW, it says 225 km/h which does convert to 140 U.S.
Congratulations to the U.K. on another cool land-speed record.
Turbine versus reciprocating parts has to be a huge factor. A 1906 Stanley was ran like those old steam locomotives. This new one is arguably closer in design to a modern turboshaft.
Steam is simply a lost art in automobiles. What's old becomes new again, though. An old steam car saved energy as hot water. Insulation around the boiler facilitated that heat storage. I recently read that the latest Toyota Prius saves its heated engine coolant in a vacuum flask when you shut it off.
Which leads to the question "What would be the best way to make a modern steam-powered land speed record contender?"
I reckon it would be based on a turbine instead of pistons, cranks and rods. Maybe the turbines should be in the wheel hubs. Is a two-stage necessary?
What are the best modern materials? Metal? Ceramic? Best Fuel? Is there a fundamental limit to how fast a wheel-driven steam car can run on a given course?
I wonder what the total boiler volume was in this one. i.e. did they leave the starting line with more or less heat than the Stanley? How do the cars' weights compare?
Did the Stanley brothers ever have electrical problems?

Not for a restoration project.
I fucking wish I had a mod point. Damn it.

He already won.
Why shouldn't a person be allowed to self-insure? Mandatory health insurance is robbery on the part of government and the health insurance lobby.

Is that a San Francisco duck or an Oakland duck?
sometime in the distant future?
oops, sorry.

Maybe they just couldn't figure out where to load the ammo.

"I was wondering. What does acceleration has to do with top speed?"
It's how you get there.
Imagine a nuclear/steam-powered penny-farthing!
Try sitting on the smokestack. It'll make an impression.
Being able to hold high-temp steam at high-pressure should be one major factor. Materials have improved hugely since 1908.
Lowering friction should be another. The piston in a Stanley was crude compared to a modern turbine shaft.
I think 10% was the right goal. 20% would have been harder to capture and made it even harder to reclaim the record next year.
All that being said, the old record is more impressive. Long live the Stanley Steamer!

Would a flux capacitor make it faster?
Inquiring minds need to know this shit.
I, also, assume that a word has the same meaning as its synonyms.
