Awesome thanks for giving all the links, what do you mean by "if my car buckles," do you mean by lagging?The SS AFC comes with R4 software that you hook up to your laptop using a Serial to USB cable.

Here is the driver you will need for the cable. It's the 3rd one down in the USB and Firewire section (DX-UBDB9)

Once you install the software and drivers, you can load any map you'd like. Here is a compilation of some of the more efficient maps created so far. The SS AFC will come with the Supermap loaded, but there are others available.

If your car buckles, get ahold of me and I'll forward you a map that JamesK sent me to fix the hesitation.
