GTech Competition Pro results hot off the presses

[rocketspeed]

Got a GTech Competition Pro for X-mas and I must say- these things are AWESOME! It tells you so much about your car, its just plain incredible. When you aren't running 0-60 or 1/4 mile times, it tells you cornering and accelerating G's with an accurate tach and shiftlights, which are most useful.

Got an idea of what the car weighs with me in it today, so I took it out for its first 0-60 run. Didn't have space for a full 1/4 mile and it would be highly risky to try it anywhere around here from a continuing to have a driver's license standpoint.

Test conditions are about 40*, no wind, flat to very slightly uphill straight strip of road. Car is bone stock. Full tank of 93 octane.

Note that the only numbers that are weight related are horsepower & torque. All of the acceleration times are based on the internal accelerometers, which don't need to know what your car weighs to work.

This is supposed to be a highly accurate piece of equipment, so that 0-60 time should be right on. I let off the gas right after passing 60, so the 1/4 mile time is just where I hit the button to turn it off and is not relevant. Again, the weight input for the car is not relevant to this figure. The 0-60 time looks pretty solid and about what I'd expect to get. Launched it at about 2k with a little wheelspin and feathering the clutch, hooked up pretty well and took off nicely. I get less wheel hop and more spin with the narrower snows I have on now and my smaller steel wheels I'm guessing shave a little unsprung weight vs. the Racing Harts.

I've got the weight of the car with a full tank at 2,800 pounds and I'm 195, which results in the total weight of 2,995 pounds.

I'm curious if this number is tiny bit light, as the horsepower & torque numbers are a little higher than expected. Remember that the GTech will register lower numbers than a chassis dyno because of aerodynamic resistance. These are numbers that I'd expect to see on a chassis dyno, although I guess the aerodynamic drag 0-60 isn't super high. Gotta find a scale.

Sweet, where did you mount yours?

Just stuck to the windshield with the suction mount. That thing is kind of a pain, but when you get it mounted right, its pretty good.

And here's a pic of the rig. Crappy resolution due to camera phone.

The wheels are just hubcaps with steelies, tires are Blizzaks.

Where did you get it and how much

Thanks alot Tony

Got it for Xmas from my wife, but I know she got it direct from them for $249.

From their site in regards to accuracy:

How accurate is it?
There are several significant improvements over the original G-TECH/Pro Performance Meter that have been implemented in the new COMPETITION model. First of all, there are 3 accelerometers and they are fully temperature compensated. This in itself is a huge improvement in accuracy. Secondly there is a very sophisticated new calibration algorithm that allows much higher precision. Also the system now has 32 times higher resolution which speaks for itself. New Noise-Correction algorithms have improved overall accuracy as well. With all of these valuable features we are very proud to announce that the accuracy is now within 5/100 second. With the consistency at 5/1000 of a second! Absolute Horsepower and Torque measurements are within 3% and consistency within .5%!

Sweet, I've always wanted one of these.

 

[mazdaspeed75]

That s pretty close

Hey man the 60 time i ran at track was2.255 1/8 was9.781 at 71.84 mph Thats pretty close what mods do you have I have injen unflashed car

 

[StarvingRussian]

sounds like a cool piece of equipment

 

[Pro5OnSpeed]

thats bitchin i need one of those.

 

[rocketspeed]

Here's my mod list:





I don't have any!

Is your car flashed or not

Is it flashed

 

[rocketspeed]

It does a hundred other cool things. All kinds of graphs showing shiftpoints, how fast you were going at different distances, engine speeds and so on. Its a goldmine of info.

Should be quite accurate to what you see at the track, although i wouldn't call it a substitute since you never really know if the ground is truly flat that you're on and so on. Seems like a great tool if you were modding, though, as you could readily see the changes in performance from your mods.

If you're like me, you don't have a dyno handy.

Re: Is your car flashed or not

Is it flashed

Unknown. I bought it after the flash came out, but there is no evidence (the sticker they put in the engine bay) that it was done.

I don't have a hesitation problem, so I never looked into it and I'm not planning on changing boost, so its not really an issue for me unless the hesitation eventually shows up.

I asked when I took delivery of the car and nobody knew.

 

[mazdaspeed75]

ok

They should be able to look it up I have the hesitation so i called them to see if it was done they told me all the ones from a specfic date were done I told them to check they said i wasnt flashed .

 

[SuperSpud]

what about your 1/4?

 

[rocketspeed]

Doesn't really matter to me. If hesistation problem appears or if I ever considered upping boost, I'd look into it.

If I had to guess, however, I'd say its flashed since I have no hesitation problem.

I took acuras and a auto mustang gt waiting on ion fmic should be here mon Hope this gets me in the 14s

 

[rocketspeed]

what about your 1/4?

As I said in my post, there was no room to safely run a quarter.
