Yeah, as long as you know someone who is familiar with ECMSpy.
Really, you can use your internet connection at home. This is the easiest way to do it:
1) Download and install a "Remote Desktop" program (I use TightVNC, it's free)
2) Set up a "guest" account in the software, so the other person can log in to your computer remotely.
3) Make sure your computer is online, and get the IP address. Send the IP, username, and password to the remote person.
4) Hook your bike up, and start ECMSpy. The other person can log into your computer from any web browser, anywhere in the world.
At this point, it will be like he's sitting right there with your bike. You can even watch on your screen while he works with your bike.
It's best to be on the phone with each other, in case you need to start/stop your bike during the tuning process.
