Default Anyone using a G-Tech?

Anyone here been using a GTech Pro or some other system? Trying to figure out if its a worthwhile toy or not. If you've been using one are you happy? Learned anything from it? Feel it's accurate? If they work well it would be 1. an interesting street tuning tool 2. useful learning tool for HPDE 3. Pretty damn cool to see your g's, hp, stopping distances, accelleration, etc.

Opinions from users?

I had one of the original GTechs, it was ok. You had to know your vehicle's exact weight in order for it to calculate HP accurately. IIRC I used it twice and then my little brother ruined the power supply with a screw.

It sucks unless you have it fully gyroscopically mounted. It is very sensitive so it needs to be set up very precisely to get any kind of real numbers i have one and at 8 psi it showed me anywhere between 180-280 whp on my miata. 0-60 was more like 0-73 or so.

Spend the extra cash and get the V-box... it's GPS based and costs a lot more. lol.

Not good reviews so far. Obviously was hoping people liked them. The idea of having #'s on acceleration, cornering g's, etc. as feedback on any changes is really appealing. "how does this tweak work vs. this one" etc.

That's because I didn't get a chance to put in my $.02 yet. I rarely use the g-tech pro because the mounting bracket broke (my fault) and I have datalogging for HP/TQ on my link but I always considered it a pretty neat toy. My 1/8 mile drags with it were pretty close to what I got on the track. I never have trusted the HP readings on it BUT I trust the 0-60, 1/4 mile, etc. The ability to do a 1/8 mile in Charleston, SC in the Miata and then go to Pensacola, FL and simulate a race against a Vette is neat.

my friend uses his for data collection during autoX. Has come in handy actually. He bought the really nice one for less than the prices of the cheap one on flebay

I guess some of the complaints have to do with units having to be mounted properly and precisely. Thats not the units fault. I figured too that the data for autoX and HPDE days has to be interesting and educational. How accurate does the cornering, acceleration and braking G's seem to be? That's the most important feature to me.

I have an original Gtech. I found it useful for comparisons on the same car (0-60 and 1/4 mile). I never tried the HP feature as it has to assume some things. Now that I am in a RWD car though, maybe it will be more accurate.
