Everyone that works on cars knows this as common knowledge. I will be the first to admit that the majority of today's engine control systems are too complex for anyone this side of a very specific hardware level electrical engineer's degree to understand. I am not here to pretend that I have such knowledge.. but if you think I will be out of a job you are not as intelligent as I thought earlier... If I don't understand it I will find someone that does, hire them, pay them and make money off of their work... that is the basis of any shop or business for that matter.
See that is how people like you, that think they are smarter than the system end up working for the man or people like me.
I am not impressed with your ability to spell.. I am not impressed with your knowledge of how motors or dynamics of motors work because talk is cheap... I would be impressed if you would put your money where your mouth is and stop being a troll on here.
I honestly am very ambivelent about your rhetoric.... you said it best when you wrote...

"You'll still have business because not everyone wants to fuck with the insides of their motor for various reasons."

So please if you want to set people straight, save your typing for someone that gives two fucks.


Cheers,
Martin
