G-tech accuracy??
 

how accurate are they??

anyone run one and compare the info to actual track times??









reason i ask, closest track is 2.5 hours away, and with my too many home improvement projects going on, don't think i'll be able to get to the track..

On the ET it is pretty accurate +or- a tenth.

The mph is about 3mph high.

It got my ET pretty much dead on, I dont know if the mph is off on all cars but it reads mine about 3 mph high compared to the track.

Actual ET 13.7 @100mph
G-tech ET 13.66@103mph

I am in the same boat as you I just bought a house and it is putting a huge financial strain on me. Somehow I still found the cash for slicks.:D

Just remember to make sure the G-tech is level and find a straight level street.

Good luck
Later,

What Dark_5.0 said seems to be a good rule of thumb. Although, I trapped 111 mph on a G-Tech but usually trap 105-106 at the track. Weird.

Ithinkthereason the g-tech reads higher on the mph is because the g-tech reads the mph the 1/4 mile point but at the track the trap speed is an aver. of the so many feet is more speed/time/dist. figur. more then an on the dot mph

My friends and I all pitched in on a g-tech and it was way off. Before the 1994 gt i had a dodge stealth es not turbo or anything and i ran 13.9. that is completly stock... LOL i thought wow this car is fast but it was really the g-tech being a peice of crap. We later found out that the disc was messed up in the tech and it was sent back because of warrenty. Now it is still a little off but not 2 seconds... but i heard good things from other people though so maybe i just had bad luck:p

I am in the same boat - 2 hrs from a dyno or track!

been looking at tazzo.
check out tazzo.com like the g-tech but suppose to use better guts and the spec's exceed the gtech and vc2000race
