Fooling the computer by butchering a signal with Radio Shack resistors... versus reprogramming the engine management computer. Hmmmmm. Maybe there's a reason why the gas mileage goes to $hit?

Almost all engine sensors work by altering a signal to the computer. This alters the signal too, so why would you single this out as "butchering the signal"?

I can't comment on whether the price he charges is fair, because I've never made one. But I often find that by the time I source components for a project, buy them and get them here, do a little experimenting, and spend the time to assemble them into a working product (and my time is never "free"), it would have been much cheaper just to buy the darned thing in the first place. And that's if everything has gone smoothly, without any major glitches.

The engine sensors send the signal to the computer without altering them. The computer then adjusts the engine processes accordingly. The XIED is the only one that alters them. Tuners adjust what the engine processes will be but still don't alter what the sensors are sending to the computer

Because it makes a fixed resistive change, adding a permanent bias to a signal that is designed to operated over a broader range.

If the signals coming from the sensors didn't change, the computer wouldn't have the information it needs to take corrective action. It wouldn't even have any idea when to fire the plugs, because it wouldn't know how fast the engine is turning, or when the piston is nearing the top of the compression stroke.
(There are rare exceptions, such as functions which are based on things like how much time has elapsed since startup).

I had a similar experience with their ViED's...
