You have to have the Power Commander Software they send you with the PCIII to open the map. :yes:g480628 said:I just ordered the PCIII USB and downloaded the appropriate MAP from the DynoJet website. When I attempted to open the map my computer could not open it because it did not recognize the .map extension. I did a web search and could not find what other program would open a.map program.
I have a Dell XP computer with the latest MS software installed.
Has anyone encountered this problem and how did you deal with it?
Thanks for any help offered.
