Whether the GTech is right or wrong I think the automotive enthusiast should adopt the GTech as a standard that we can all measure against. The GTech's themselves will all read the same and as long as the user properly zero's the unit out we should all get results that we can compare on a level playing field.

So what if they all read .3 seconds too fast or .1 seconds too slow. If we are all using them then we can compare results. If my car hits 0-60 .4 seconds quicker than yours, then it doesn't matter how it is measured...it is just faster.

Sorry for rambling on, but I get a little tired of people criticising the GTech. It is what it is...that is all. The average enthusiast does not have access to the measuring tools the magazines have. All we have is the GTech.

run1: 5.43 N->S (launch @2500)
run2: 5.30 S->N (launch @3000)
run3: 5.43 S->N (launch @2500)
run4: 5.36 N->S (launch @3000)

I have '99M3/2 with NO engine mods (only some brake mods). I am running S-02 (with 6 track days and 12000 miles on them). The temp was about 74 degrees. For those in the bay area, I was on that strip of Mary ave in Sunnyvale, just North of Maude (very empty and wide).

As you can see, I went in both directions on the same road (N->S, S->N). I tried launching with little to no wheelspin (2500RPM), and seemed to get consistently slower results. The 3000RPM launch's had some wheelspin for about 1 second. I did a few practice runs before the recorded ones, and I was consistently get in the 5.3's w/wheelspin.
