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

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

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.

We did not move it from car to car, we just don't keep it mounted to the windshield all the time, because we actually drive the car like normal people, and it helps to be able to see out of the whole windshield. I recalibrate it everytime we get it out to use it, and make sure the axis are at ~0 when it is mounted. And for about 2 months we had it mounted to the windshield the whole time, and it was consistantly incorrect as it is now. I know how it works, it just isn't 100% accurate and you can't expect it to be. And as I said, it gives us those incorrect times consistantly. If we get faster the times will also get faster around the same amount. I updated the firmware last night in hopes that the 3.0 is gonna work better than the 2.0 it had, but I will have to see. It just isn't accurate. We may run it the next time we go to the track with the new firmware installed and see how it works.

Yup, the car just happened to get to 105 1.3 seconds quicker with no track prep, with a worse launch, with a passenger in the car, and spare tire in the trunk, and on pump gas, im sure thats exactly what happened. Ummmm... NO!

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 ever remember saying I was unhappy with it. I said it is a very nice tool to see if a mod has made an improvement or not. It is very consistant with itself, so it is very good for that. But what I am saying is, you can't say that your best time is a 14.90 if that is what the G-Tech said, it is a computers and computers make errors, the only way to be 100% sure how fast your car is is to take it to the track and get slips, that is the point I was trying to make. Actually we use ours quite often, and really I like to see the cornering g'* a lot. And maybe there was an error with the software on it, anything is a possibility. I installed the 3.0 version on it from the 2.0 and I will test it out next time we visit the track, that may have been the problem. I will let you know after we go to the track next time.

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 )
