I did it using a USB extender and 100 ft of cable. It was tough getting my bike up the stairs and through the kitchen door! Just google usb extenders, and you will find the best price.

3 meters should not be a problem. I don't know how fast the communications rate is between the ECU & the PC. It probably is not all that fast but 100 feet still seems like a stretch. But if it worked, who am I to argue. I still would not use an extension any longer than necessary.

The extender I bought say's it's good for 150 feet. It works fine.
That must be some kind of powered extender. Plain cables will not work that far. From USB.org:

USB Info: Frequently Asked Questions

USB Cables, Connectors, and Networking with USB

Q1: How long of a cable can I use to connect my device?
A1: In practice, the USB specification limits the length of a cable between full speed devices to 5 meters (a little under 16 feet 5 inches). For a low speed device the limit is 3 meters (9 feet 10 inches).

Q2: Why can't I use a cable longer than 3 or 5m?
A2: USB's electrical design doesn't allow it. When USB was designed, a decision was made to handle the propagation of electromagnetic fields on USB data lines in a way that limited the maximum length of a USB cable to something in the range of 4m. This method has a number of advantages and, since USB is intended for a desktop environment, the range limitations were deemed acceptable. If you're familiar with transmission line theory and want more detail on this topic, take a look at the USB signals section of the developers FAQ.

Q3: How far away from a PC can I put a USB device?
A3: With the maximum of 5 hubs connected with 5m cables and a 5m cable going to your full speed device, this will give you 30m of cable (see section 7.1.19 for details). With a low speed device, you will be able to get a range up to 27m, depending on how long the device's cable is. With a straightforward cable route, you will probably be able to reach out 25m or so from the PC.
