^ Same thing happened when my friend Ron member BLUE STINGER tried to use one of these supplied cables on a 02 wrx to tune a car, tried many things and no worky. He pulled out his 2.0 tactrix cable and bam. Tried the 1.3 cable and it worked fine as well. This bfm cable did work on his gd sti just fine though. He said maybe there is a trick to it to get it to work on the earlier wrx's, maybe its just timing.
