Is this G-tech thing forreal?

[fostytou]

How can they sell this for that much? g-tech pro

It just plugs in to your cig lighter and then gives you "surprisingly accurate" hp and torque readings along with e/t times and a bunch of other information that I'm sure is worth it

Here is the manual, in case you are interested. It seems the whole system is based on 2 things: your RPM of the cig lighter, and some g readings from the unit itself (in addition to settings like car weight etc)

 

[mitsuclipsegsx]

yes it actually does work i have the older type g-tech meter and i can prove it cause we used it on my bro car and he went to track and was w/ in .5 i have used it it, its only good for 0-60 and 1/4 et is way off and dont even bother w/ the hp but i bought it for the 0-60 and 1/4 and works great

 

[Endz0r]

.5 is a big difference. especially when you go from 16.5-16.0 to 11.5-12

.5 is a big difference. especially when you go from 16.5-16.0 to 11.5-12

within .5 is prob a hellofa lot better then your a$$ dyno


HP is prob close also , as long as you know the true weight on the car and 1/4 times are close then its nothing more then a formula.

there is a tad more to it then car weight and the cig lighter

 

[ryanman]

I have an older model G-Tech and the new model G-Tech, both are very accurate on my 1/4, 0-60, 60-0 and the HP reads about 15-20 hp too high. I think they're awesome for getting ballpark figures.

 

[MyEclipse5]

Do you just plug and play? Do you have to set anything up?

 

[ericbev]

I beleive they are plug and play.. correct me if i am wrong

 

[sxevegan]

i had the old style one. They can be had on ebay for like $40 now. For 1/4 mile, 0-60, and 60-0 you don't need tp enter anything. You just need to make sure that it is mounted perfectly on the windshield (you calibrate it by tilting it up and down before each measurement is taken). For hp you need to enter in the exact weight of your car (with you in it) and it will be a pretty accurate representation of what your putting down at the wheels.

 

[fostytou]

obviously I knew it could come close, but I guess I'm surprised its that close. The manual says it has about 10 min setup time (though it seems like just a bit more) but other than that you plug it in to the cig lighter, setup your rpms and other junk and you are good.

then you can download 15-20 runs onto your computer (via serial connection)

it seems like the 1st gen of it is $40 shipped but the newest one is still in the $250 range

 

[pacent]

Its good for say, if you install a mod and see how much hp it increases or how much faster you go 1/4 mile, relatively speaking. Don't expect an exact time though. You also need to use it while driving on an absolutely flat surface.

 

[marcmsj]

according to the website, the new one is accurate in the 1/4 mile to +- .01 seconds which is pretty damn good. they have a video demostration and the g tech and time slip were dead on at 14.29

i might have to pick one of these up and see how i like it.

They are EXTREMELY accurate if you use them correctly and you are testing on a FLAT surface. I have used it on all of my cars and many friends cars which we had also taken to the track for real times. Here are my results:

-------Car---------------------------G-tech Time -------------Track Time

1) 96 Volvo 850R - 13.89 @ 105 - 13.94 @ 102
2) 95 Eclipse GST - 14.54 @ 103 - 14.41 @ 100
3) 92 3000gt VR4 - 12.45 @ 112 - 12.56 @ 110
4) Stock 92 VR4 - 14.1 @ 100 - 14.04 @ 98
5) '04 F250 Diesel - 13.78 @ 99 - 13.90 @ 97

As you can see the times are very close, keep in mind these are the best times out of a couple runs. One thing i noticed about the gtech is that it usually gives you a trap speed about 2-3mph higher than the track, this is your ACTUAL trap speed, however, at the track, trap speeds are always averaged in the last 30 or so feet thats why they are lower at the track then on a gtech.

This was done on an eBay $40 gtech.

I LOVE that the ginormous F-250 was the second fastest one there ahahaha thats good stuff..

anywho, I just bought the newer style G-tech pro off ebay for $120 it was also recently upgraded with the new software. hopefully it works good.

0 - 60 can be calculated pretty easy by logging vehicle speed and using the timestamps on a nice, fast logger .
Want your 1/4 time? $15 gets you into a lot of tracks.

how much would a 'good fast' logger run in costs including all the needed cables? [ i'm curious as i am probably going to look for one in the coming months ]

how many tracks are open in states like mine[ NY ] .... none. not for awhile. Not to mention they are like 45 minutes away [ like 4-5 bucks in gas to get there ]

The Gtech is a good cheap tool to provide a benchmark and to get a rough estimate of what each mod gives you. I know its not the best tool, but your can do it like anywhere[ find a flat strech of deserted road/pavement..take car out..do 2 runs.... done] do some more mods, head out to that flat stretch again

no track fees or waiting in lines at a track [dependant on location] .

it has it's use, and for 40 bucks it doesn't seem like a bad investment.

Also - nice sig

Exactly, i don't want an EXACT TIME that i can post online and brag to all my e-buddies. I want an estimate, and with that i don't have to drive an hour to the nearest track just to make passes all day. Then come home, a month later put on a new mod, go back to the track (another hour) its jsut easier to get a rough estimate.

BTW someday ill have an exact time that I can brag to all my e-buddies..but its winter.

Actually, Autometer is coming out with a 2 1/16 gauge that does everything that the G-Tech does. It's called D-PIC and they will cost around $200. I've actually see one of these work, and I was quite impressed. I plan to purchase one next month.

 

[rowlex]

Neat. You guys can also pick up an HKS turbo timer type-1. It hooks to your ECU rpm/speed wire's and has an automatic 1/4 mile timer, and 60 mph. It's killer, it auto-senses the cars movement and starts the 1/4 mile timer. they run about 120$.

Looks pretty sweet. After some reviews, I'll probably get one.

A little OT but heres what they need to do:

Have a box that you can pput somewhere that has Oil preassure, EGT, Boost, A/F, Knock, etc hookups all comming off of it. so you can run the vacuum lines from that to your source, etc etc. Then it electronically hooks up to one gauge (or more) than you can cycle these things and look at them all. So you would only need one gauge to see your boost, knock, EGT etc.

That's kinda what Autometer is doing with their new Nexus gauges. Everything connects to one box and then each gauge plugs into the box.

They stole my idea!....kinda.

I got my G-tech Pro today I must say it is fairly convincing to be accurate.

I only had my previous 1/8 mile times from the 14b turbo and I now have the t4.

my previous best at the track with 14b @ 20 psi - well tuned

9.4 @ 84mph 2.5 60'

today with the G-tech on t4 @ 15 psi no significant tuning yet.

9.1 @ 90mph 2.5 60' 1/8
13.3 @ 113mph 1/4

289hp @ 6,6xx rpms
243tq @ 5,5xx rpms

weight entered as 3,250

full weight 98 GST Full tank gas I weigh 200 lbs.
only weight reduction is spare tire area emptied out.


this seems fairly correct to me I mean I have not done a seconds worth of tuning have no idea where the timing is or anything because the logger has been messed up.. But given the ASS dyno if before and after and the closeness to 1/8 times + some power. I would have to say it is fairly accurate..

check this out: it plugs into your obd port sirectly with your ecu and tells you in real time all the vital inyour car. looks like they made your idea better.
