As such, all ECU, doesn't matter if its a power FC, AEM, haltech, megasquirt, big stuff, etc... ALL work the same. They ALL have a fuel map, a spark map, and configurable inputs/outputs that operate on the same basic principles of voltage, pulsewidth, wavelengths, triggers/switches, etc...

So for instance if I had never touched an AEM... I should still be able to figure it out within a few minutes just by looking through the software. the best tuners can write your fuel map and ignition map before you even start the car, by doing some basic algebra and using instinctive knowledge about engines, regardless of what kind of computer is installed. Any "tuner" that says "I only tune X computer" isn't actually a tuner.

Your theory is right but some people just feel comfortable with what they know its just the way the world is. They might be able to do it but its going to take time and time is money when the car is sitting on the dyno.
