i keep hearing people talkin' about it. $125 sounds like a good price, is it worth it?

 

Well I have one, but I don't use it very often, it keeps falling off because the cigarette lighter socket is so far back.

 

Mingster: Is that the new model? Website, gtechpro.com says, "new model, Old price: $139.95." dgl1

 

i have zero idea. i didn't know that there was a new model out...

 

My girlfriend ordered one for my birthday. Should be getting it Tuesday. I'll let you know if I'm impressed.

 

dude, awesome girlfriend you got.

 

I think(not sure tho), the old model was called G-Tec, and the new model is called G-Tec Pro.

 

I've used my friend's g-tech and it is fairly accurate, and fun for first few weeks, as figure all stuff you test, then it's useless unless your upgrading your car.

 

If you want to see wassup with upgrades a G-tech is not very useful. Since it can ONLY measure performance with a heavy dose of driver skill and related variation. So you can't relaibly see if something is working or not unless it's a rather large change. Units that allow programmable speed to speed measurement are much more useful for that purpose. For example I compared various air filters and found 1-2 HP from an ITG over a comparable K&N. Speed to speed tests basically have you floor it in one gear (no high rev launches or shifts, no need for as many repeats to get good info) from say 30 to 50 MPH. Or any other speed and therefore RPM range. With no changes you can easily repeat to tiny fractions of a second. The 'puter can tell when you hit 30 mph and 50 mph and then can spit out things like power torque, time, distance and so forth. All you have to do as a driver is hold the gas pedal to the floor. Tons of hyped up products do nothing, very little, or even hurt performance. Yet the results from the butt dyno can be quite different.

I got a Gtech Pro (and got an extension for the cigarette lighter plug). It's very entertaining for a few weeks. Now it just sits in my secret compartment. I lend it out to friends who want to see what their car will do.

My problem is threefold.

1. After you run your ar a few times, you know what it can do. It's no longer interesting to keep running the same thing over and over.

2. As mentioned in an earlier post, the variations are usually due to your driving. So it doesn't work for testing upgrades really. However, it is fun to learn how to relate measurements to seat of the pants feel. For example, did you realize that at full throttle, the S2K pulls between .27-.50 g's. When you mash the brakes, you can easily get over 1 g. Normal "heavy" braking results in the .7-8 g range.

3. In my daily drive, I rarely find an opportunity to use the Gtech. It's a thing that you have to prepare for. You can't just spontaneously turn it on and use it. So I don't find a lot of time to use it.

At the end of the day, it's a really entertaining device. Gadget freaks (like me) will get off to it's capabilities. However, it's definitely something that you'll use less as time goes on.

Of course, if you are a drag racing junkie like Sev....
