There's actually a few versions of PowerFC software (and cable).
Apexi FC Pro - Power Excel Tuners only - Not For sale
Apexi PowerFC Excel Software - Retail version - $460 AUD - Its a cut down version of FC Pro, has limited features. Basically read/write maps and change the same **** the hand controller can do.
FC Datalogit - The 3rd party product by the NZ guys. $500 AUD with cable/dongle and software. Access to all the hidden stuff from the hand controller. One unit does mutliple versions of PowerFC (ie: Skyline, WRX, S15, Silvia, GTR) etc.
FC Tune - Free 3rd party product being developed by a guy in Germany. It's nearing completion and is an alternative to datalogit, offering a better interface, more bug fixes, better features and overall better usage. if you wish to check it out have a look on the rx7 forums http://www.rx7club.com/showthread.ph...5&page=3&pp=15
and look for "FC Tune" thats the program. You can download and use the beta but you'll need a datalogit of apexi cable.
