Hypertech Problems!
When I first bought my 98 z28 I was given a power programmer III also. The problem is whenever I plug the PPIII I get an error message that states i have the wrong vin number. I have sent emais to Hypertech, but they do not respond.
What should I do next?
I used one on my old '97 LT1 Trans Am and was mildly happy with the results. Ever-so-slight SOTP improvement...the modified shifting was more noticeable. Other than this, it's also nice because you can change when the fans come on, to take advantage of a lower t-stat. I don't think this is a big deal with LS1s, I think they run better a little hotter than LT1s.
I was in the same boat as you when the hypertech first came out for our cars. I bought a used one for "cheap" off ebay that was supposedly taken back to stock....it wasn't. Hypertech absolutely will not unlock it for you or reprogram it....believe me, I tried. Throw it away and buy yourself HP Tuners or EFI Live.

You said you got the Hypertech for free, I agree with jmm98LS1, cut your losses and smash it.
Ls1 edit or Efi live maybe..but not hypertech
Like others have said, look into Hp tuners or Efi live. Dont even look at ls1 edit, unless you can get it dirt cheap or free. Browse around in the pcm section. Both Hp tuners and Efi live stomp the dog **** out of Ls1edit when it comes to upgrades and customer service, as well as ease of tuning. Hp tuners is year locked, not vin locked and its doesnt cost much to upgrade for different years. Basically you can tune all 1998 model years Camaro/Firebird and for a little extra you can buy the 2002 model year, and it doesnt have to be F-body. So if you have a truck and they support it, you can get that software as well. I dont know to much about the licensing of Efi live, but it's probably what I'm going to go with. They both are hard to chose from.
