The learning curve has become a bit too steep with today's modern SoC systems. You can't just wire a transistor to a parallel port and call PRINT LPT(0),128 or whatever the hell the call was. You need to write a program to call a userspace driver, or modify your kernel, or whatever else you need to enable in the platform.c file to enable the port to raise the GPIO to blah blah blah I quit.
So now his brother, if he wants to tweak a setting on his ECM, needs to understand how to hack into the module without bricking it. Then he needs the correct tools to create the new engine profile and burn it in. There's probably a hardware dongle or two involved. Does that make sense?
