The man who says something is impossible, is usually interrupted by the man doing it.
ahhhh just generate the signal
i betcha you could just record the signal from the vss with the soundcard input, loop it, and play it on output
just dick around with the gain (volume) till it actually accepts the signal and moves the speedo
mechanical solution to electrical problem bad
Yep, that's definitely possible, though I would use a function generator if it were me. Sometimes the simple solution to some people is the mechanical solution. ;)

simulating a hall-effect sensor? a 555 can do that without any issue.

I am not the most computer savy person out there. Simulating the signal? How in the world would I even be able to do that. Would I need some type of special program? What would I hook to my computer to hook to the speedo? Would it be usb powered/operated? I would need some very detailed and very easy to follow instructions.

i have just done this im using a free signal generater to input rpm to my flowbench ecu so it will read maf soundcard is all you need 12kb download LOL i can set rpm to up over 9000rpm square wave

i never see suggested schematics for any of those which makes me somewhat nervous about potentially overloading the sound card.... i know most/all are okay with 64 ohm loads, but i don't know how much lower you can go with impedance.
i've got an otherwise unused soundblaster laying around, but that would need to go into the desktop and i tend to need my testing stuff on my laptop.
