I have been lurking on g35driver since i got my car in march 07. About 1 hour ago i got the GTech from a friend and tested out the 1/4 mile. I ran a 14.18 with a 2.143 60' and a trap speed of 99.35mph. The runs were done at a local empty back road. Tires are stock potenzas that have about 30-35% tread left and tire psi was at 32 warm and 28 cold. Temp was 68 and humidity was at 87%. Elevation is roughly 500-700 ft above sea level. Mods include K&N/Chrome Z-tube, MREV2 + 5/16 spacers, Strup TP, HKS hi power ti TD that go along with my Rev-Up motor. My car has been dynoed with the Hks Exhaust, Mrev2+5/16 spacers, and K&N Z-Tube at 260.2hp and 235.tq on a Dyno Dynamics Corrected cant remember if SAE or STD; Temp was 69 and humidity was 70% From my understanding the Gtech is not always 100% correct so i was wondering if someone could give an educated guess on the correction as well as tips on ways to improve my 1/4 mile. Thanks

I tested my other car out once with the newer Gtech pro and then took it to the track, it was within .1 of each other. Good tool to see where your at though.

 

how much does a gtech go for?

 

300 bucks

 

ebay is also a good place to look, I picked mine up for $200

 

cool...thanks!

 

how would i know if i calibrated it correctly? my rpms seem 100-200 off sometimes as well as pitch factor thx
