accuracy of Gtech Pro device

Re: accuracy of Gtech Pro device

oh btw shaun,

then its much cheaper to buy a stopwatch ... ??? eh??? since that is apparently all it can do what with the numerous "problems" u mention ...

& i still stand by my earlier comments.

Sorry you haven't given any of this much thought at all.

Here's what you need to do if you think it is physically possible, and if you think it will save time and money over a quality accelerometer...

1) Buy a stopwatch as well as an accurate distance measuring wheel
2) Measure and mark out the eighth and/or quarter mile distance
3) Call up a buddy and get him to meet you.
4) Somehow sync buddy's stopwatch finger to actual movement start - not engine rev, not chassis stance change, but actual movement off the line.
5) Also sync this same buddy's eyes and finger to marks at eighth and quarter mile - not anticipation from exponentially changing scroll speed, but actual crossing of the mark. He also has to sync his vocal cords to let you know to note speed as you cross the marks.

Only after this will you have ElapsedTime@Speed. There is one variable in step 4, and three of them in step 5. In addition to these 4 variables, your speedometer lacks necessary resolution. On top of this heap, the magnitude of most of these variables remains fairly constant no matter what the car - so the quicker the car, the larger the % error.

Besides, even if you perfect above system and remove variance, the figures you end up with are not comparable to those of the Gtech users (large number standardized systems vs your proprietary one).

You're free to stand by whatever comments you wish, regardless of whether they are right or wrong.

it's your opinion that i have not given it "much thought at all".

considering all the "variables" that you have mentioned regarding the inaccuracies that could apparently creep in & the non-existent pre-sales attitude of these people, i might as well include yet another variable with a manual stopwatch and exclude the problems of after sales service which is certain to be non-existent.

and are entitled to take up the cudgel for such individuals ... whether they are right or wrong. but that does not make you right.

i, for one, will never purchase a product from a company that ignores a potential customer. you are free to do so.

and this IS my considered opinion.

Re: accuracy of Gtech Pro device

Shaun, if you offer your honest comments and experience with the device, and somebody chooses still to think it's not worthwhile to get it, then bopian la... For me, getting a buddy to hand-time vs the G-Tech - it's a no-brainer, I'd definitely choose the latter any time.

Which set me thinking... whether I got 7.9s or izzit 7.2s for my Bimmer last time, hhm. :thinking:

Physics and biology don't equal opinion. I've logically listed the challenges you will face trying to get ET@speed from a plain stopwatch like you earlier suggested.

You keep going on about aftersales, when, to begin with, you didn't read their detailed FAQ and then got offended when they didn't reply to questions already answered. Your fear of lack of aftersales is an entirely different issue from the accelerometer vs stopwatch one, and they shouldn't be mixed.

In quantification method comparison, there's always one more accurate, and another less accurate. In this case, one is a lot more accurate than the other - one is a lot more right.

Dear Axl the Rockstar, I believe you got the digits reversed. It was 9.7s and not 7.9s. I remember because of the hysterical call you made to everyone right after the event - giddy with joy at having broken the 10 second century sprint barrier.

No la... can't be mountain-fish! My 328i can't be that slow... even taking into account the CMI driver onboard.

u obviously didn't bother to read my post carefully ... seems like you have a need to mouth off ...

i referred to pre-sales ... NOT after sales ... i did not get one, so after sales is not even in the equation.

secondly, i did NOT get answers to my questions from their so called "detailed FAQ's" or from them.

further, i did mention that the device may be good, but i needed answers before i buy one.

you are the one confusing issues, not me.

in any case, i do not wish to continue this inane discussion with you. believe what you want ...

u r obviously obsessed with the device and cannot understand or appreciate other peoples comments pertaining to the kiddies who make it - as opposed to the device itself.

...yet here you are... doing what? I'm quite glad I have a fellow mouth-er off for company actually.

ok.. pre sale. sales issue.. whatever. This is the tech section, not the long-drawn-whine section.

secondly, i did NOT get answers to my questions from their so called "detailed FAQ's" or from them.

Read the questions you posted earlier on in this thread. You obviously still haven't read the FAQs. Go read it and have most if not all of your questions answered. You don't have to have everything spoon fed to you.

further, i did mention that the device may be good, but i needed answers before i buy one.

So go read the FAQ, then ask a question that isn't covered by the FAQ or that hasn't already been answered in this thread. If they don't reply to emails, call them, and repeat. There are always ways to get answers as long as you truly want them. I could list your exact questions that are already answered on their FAQ, but I don't feel like spending more time on someone who won't even try.

you are the one confusing issues, not me.

Do you or do you not have any problem with the stopwatch vs accelerometer issue you raised? If not, good, because I really don't care about anything other than that. If so, what exactly?

in any case, i do not wish to continue this inane discussion with you. believe what you want ...

Sure no problem.. I'll continue to believe in established basic physics and biology.

u r obviously obsessed with the device and cannot understand or appreciate other peoples comments pertaining to the kiddies who make it - as opposed to the device itself.

This isn't about Gtech. I don't own a Gtech - never have, and have no intention of getting one. An accelerometer is an accelerometer. Doesn't matter if it is by Gtech, Beru, Pi, Marelli, twx.... at even the most basic modern day specs, they will trump stopwatch and human every time.

BTW, Gtech was designed by a man and is manufactured by men, not kiddies.

You have problems separating your emotions and technical issues. Don't take Gtech's silence so personally.

================

Axl, don't be so hard on yourself. I don't think you're that bad a driver. It's just that the high heels you had on, probably got in the way of reaching true WOT. Frankly, the fact that you can even break 3:00 at SIC in stilettos is amazing.

good 4 u ...

keep mouthing off at yourself ...

btw, do u actually understand the difference between a comment on presales and the equipment per se, or r u that intellectually challenged???

You have 0 points made on how the product fails to calculate accurate ET@speed.
You have 0 points made on how stopwatch is superior to product at arriving at ET@speed.

See below all your comments on presales. Not just "a comment", but a flood of comments, all of which have absolutely nothing to do with how the product actually works.

i'm pretty pi**ed off with those kiddies @ gtech ... here's why ...

..... ZERO response from those idiots.

they have their plate full with local orders. they do not give a s**t for international orders.

... the frustration of [not] getting answers prior 2 purchase from those ppl made it an exasperating experience.

here are some of the questions i asked, for which i have received no responses ...

what would u think if u got no answers to these questions?

well, zero response to pre-sale enquiries is worse than poor customer service simply becos it implies arrogance on their part ... a "take it or leave it" attitude.

exclude the problems of after sales service which is certain to be non-existent.

i, for one, will never purchase a product from a company that ignores a potential customer.

Not interested in your whining.

Not interested in your coarse language from the very start.

Not interested in your bad attitude and lack of logic.

Very interested in mouthing off on anything technical.

likewise ... so keep yr BS to yourself. i really do not need yr opinion (which is useless) or your attitude (which is that of a kid with a broken toy) .

go play with your dolls little girl.

Re: accuracy of Gtech Pro device

Guys, lets hold off the personal remarks and stay on track. Will monitor this thread for a while more - if there's no additional contribution to the topic, i.e. regarding the accuracy of the Gtech devices, then I'd deem that the topic is covered sufficiently and will proceed to close the thread if necessary.

Thanks.

Re: accuracy of Gtech Pro device

....kid...

go play with your dolls little girl.

Please MaxiPad, the hurt is too much to bear. First Nick and Jessica break up, and then in recent times double whammy of Britney/K-fed breakup combined with you calling me a girl with dolls... all this within a span of just months. The world just has turned so dark and I'm so lost. I feel horrible and I don't know what to do. The last time I cried this much was when Brad and Jennifer broke up

Looking at the RR as well. Lets see who else is interested. I might be shipping my wheels out soon so i will try to see what arrangement i can make to send this out as well saving on freight, Those interested put down ur name here. Time is of the essence so please put down your name if extremely keen.
