What Others Have said:

Your kit worked perfectly. I changed  #13 rolling radius in inches from 104 to 113.
My speed went from 32 mph to about 37 mph.
My computer has windows XP professional version 2002 service pack 3.
I used Belkin USB/Serial adapter: P73737/F5U409-CU.
I was happy with all your instructions.
The Auto Select port did not work. My son said the program was selecting a
 modem that was using Comm 3 instead of the USB/Serial adapter plugged into Comm 5.
We manually selected Comm 5 and then the card downloaded perfectly.

Hey Bob I got my programmer today, I tried it and it works great.
I did just like the other guy and changed #13 to the same settings as he did and I get
20mph on the SPEEDO, so that is really 40mph since I have the 7.5HP motor and the 4 pole magnet
to fool the controller and I turned the regen off so it free wheels better and saves battery life, it works like a charm.
I have windows XP Home Edition and a BELKIN USB to SERIAL CONVERTER

The Interface cable connects to your Laptop or PC and to the 23 Pin Main Plug on your T3 Controller.
The Detailed Instructions take you step by step through the Software Setup.

PLEASE NOTE: This cable is a 9 Pin DB9 Serial Port Cable. Make sure your computer you plan to use has a True Serial Port.
The Serial Port on your computer will have 9 Male Pins, do not confuse this with the monitor connector.
I have used USB to Serial Converters, some work some don't, I have had good success with the
Hawking UC232S   Make sure any you try has over 230kbps Data Transfer Rate.
I have also used the Cables Unlimited Model USB-2920, purchased from Tiger Direct for about $15.00
The USB-2920 was  little harder to install.

Some have also used the SYBA PCMCIA Model SD-PCB-1S, with success, but I could not get it to work.
Some of the reviews also mentioned it worked well but very difficult to get operational.
