G TECH RESULTS

AAAAAAAAAAAHHHHHHHH ....... now i think i see the problem. you are moving it from car to car. when you do this, you need to make a few passes with it to reset it to that car, it still has the readings in it that you set, but if you move it, the axis is off till you make a few runs for it to recal itself again. an easy way to check this, look at the g meter when you put it in, it should read very close to zero. if you read the manual, it tells you that you need to make a few runs for it to set the axis in the car you are running it in, this has to be done if you move it from car to car, adjust it in a car, even take it out and dl the data to the pc and put it back in the car. if this isnt done everytime that it is moved, it wont be accurate

exactly. that is how i tested mine, i had it in the car for a few months then when i went to the track, i turned off the tree on the g tech, after i prestaged, i hit the "OK" button to start it, then staged,afterwards i compared the time slip with the g tech info. it was within 1/2 mph and .020 secs within eachother. to me, that was very close.

i'm supprised someone hasn't said this yet, you can not say it is inaccurate unless you set it up properly and then run it at the track and compare the timeslip to the unit. for all you know, that'* what your car ran that time

ok, i withdrawl my bid then, i just know that mine works very close and well with in the range of error that they say. also, 99.9% of the time, it is user error that makes the tool not work right. but there is times that electrical problems may arise too.didnt mean to ruffle feathers here, but i know i have tested mine at the track, and it was very close to the time slips.

I don't think all of their units will be as precise as they claim, some may be off, as no one has perfect manufacturing skills in any real world product (ESPECIALLY cars and automotive products 
)
