Just wondering if you're interested in a lower-cost hardware option to interface Power FC to a computer PC or Laptop? It supports both fc-edit and fc-pro (power excel official software), has analog inputs, works with old (eg: toyota) and new power FCs, and has USB built in, not RS232. So it supports as much as possible. Check out www.fc-hako.com if you want more details. If you already have datalogit, then don't worry.
