It seems like we're in the same boat. I've had no luck with the 2 different BlaZt USB cable on 3 different laptops and 3 different cars (a 95 TT, a 240sx with RB25DET swap, and a 93NA). I've also had no luck with an R-VIT type 2 on my 95TT. I've been looking around on the net for a solution but have not found any.
