can somebody explain how to use a pfc .. How do you load maps and stuff like that?? Is it similar to a haltech??

 

It's not similar to a Haltech. You must input each data value by hand. Search for Datalogit on this forum, it allows maps to be dumped in from a laptop.

 

If you get a DATALOGIT then you can load whole maps
easily if someone sends theirs to you. Otherwise you have to key it in with the commander, one cell at a time for all 1200 cells.

The manual tells how to do the later.
