Speed kills, but beauty lives forever
Recently there's been a slew of motor vehicle hacking. Well, here I am talking about even more.
In Europe around 2000/2001 it was decided that 200 mph is too fast for a motorcycle so they said any motorcycle that could excede 187 mph would be banned. Well, what if we were to buy a speed capped motorcycle and...modify it?
So the ZX1200-A2 is capped. The ZX1200-A1 isn't. When comparing the two we find 1 extra wire in the ECU, engine control unit, and obviously this is the thing limiting it. Right? The new wire is #9 yellow which connects to a sensor. This seems to be the thing that limits the speed. Cutting this wire seems logical. Break the connection and it'll work perfect...Right?....wrong, this causes it to go into a fault mode. This causes the exact opposite reaction. The bike is now limited to much slower of a speed. The normal voltage on a signal is 5v and it works out to be 3357Hz while going 186 mph. If we could replace the signal being sent with a signal that never goes past 3000hz then the motorcycle will never stop it's advance of speed until physically impossible.
Good stuff. Here's a link to a guy who ended up putting Unix on his bike, among other things.
If you have any good motorcycle hacking tips post a comment on here. I kinda got onto the whole motorcycle thing cause my friend just got a new bmw motorcycle.
