You can open the box, pull the ROM, read it into your computer and decompile it with Ida, just like I did. Nothing keeping you from doing that. But, I think you are referring to going the greasemonkey route and trying to tap into the consult port. Yeah, there's lots of problems with that. But the ROM code, which houses the program and reference maps, is not locked in any which way. The original article is talking about going into the ECU itself, not piggybacking through the consult port.
Both OBD1 and OBD2 present interesting issues trying to go through the consult port, but that's not the scope of the original document. The code itself can be read and disassembled without any special program/hardware. There are no locks.
In the grand scheme of things is anything important? The sun will eventually burn out, probably long after the human race is extinct. You wont be around either. We're just passing time here.
engines. Your 240sx can make a good bit more power with proper tuning too. Check out http://ashleypowers.com/Zemulator/Index.htm
This is the one for my 300ZX twinturbo, but the ECU's are essentially the same and I will be coming out with a model for the KA engine.
ITs more a matter of "how many people will possibly hack the ECU and do we really care of they do?" The potential to blow your engine up is very much a concern to the owner, but to the manufacturer, they'd love to see you break things and pay for parts. There was already a case pertaining to exactly this topic - it had to do with ECU error codes. Car manufacturers were trying to lock it all down so only a limited number of places could perform diagnostics. This would have created a closed market for auto repair where you had limited options as to where you could get the car fixed - this would have killed the small-business auto-repair industry. The courts said hell no to that one. Since then, the ECU's for all practical purpose are open source - or at least to anyone who has the skill to open it up and read the code.
Congrats. Its not about 'racing' per se. Its about a hobby, an interest, a way to spend time doing something challenging. Some people get their nuts off building computers, some writing code, some hacking corporate networks, whatever it is - but they enjoy doing it. I dont know if you are a happy man in your life, but to say people are 'mildly retarded' for doing something not only that they like and something challenging to them, but something that would send most people off with a headache because of the complexity of what it is they are doing is simply a ill-guised and idiotic statement.
TUning an engine requires that you have knowledge of mechanics, thermodynamics, physics, and chemistry. You dont just get in there and start guessing on what to change. Building your own EFI tuning system in the world of electrons, and then applying that to the mechanical world and actually get the results you want (or have the ability to predict the outcome of your next change) takes skill and experience I think very few people possess. Have you ever hacked an ECU and built your own engine? Could you even do it?
supposed to exist?? I recall researching this subject only a short while back and it was theorized that gravity traveled much much faster than light, somewhere like 10^8 * C! One of the ideas here was that if it took gravity that long to work, orbits of objects like planets and whatnot would be destabilized. They would not maintain a smooth orbit like we see.

Check out my site, Windoze can do a TON of other things you'd rather not do yourself, but I'd personally rather drive the car myself - 450HP twinturbo 300ZX and let a computer drive? Uh, No thanks, I'm in the driver's seat on this one.
Look at my website to see: http://ashleypowers.com
I'll never let a computer drive for me, I have too much fun doing that myself, but I'll let it do everything else and Oh-My, can it do a lot.
Depends on what you classify as the "universe". IF you classify the expanse of space, then I'd agree with it being "unbounded". But if you classify the "universe" as the matter contained within it, there is a finite "volume" to the universe, of which is constantly changing, but not infinite. Ad nauseum, really..:)

An EPROM emulator will allow you to change ANY part of the code in the ECU. It turns the stock ECU into a fully manageable EFI system.
Someone has to set the bell curve. :) You sure about that torque figure though? Seems a bit high for a V6 pushing only 550HP.
http://ashleypowers.com/Zemulator/Index.htm A little something I'v been building for market. :)

ahead of us it is sickening.

But forget letting it drive, I'd personally rather pilot my 450HP twinturbo 300ZX myself and let the computer do everything else.
