Just wondering if any of you have the G-tech Pro and if it is as accurate as they say!

 

Their OK. It is Not very consistent in the HP or 1/4 readings. I take several tests then average. 0-60s works OK .. Its fun to play with , but it's not the track..Keeping it level is critical..

 

Thanks for the info-

 

Yeah, it is decent for what it is... a relatively inexpensive accelerometer. Compared to a Vericom, its a toy.

However, it has some merit. Forget the HP/TQ readings. It makes a lot of assumptions there, and the 1/4 mile trap speed is high. But I've found the 0-60 times and 1/4 mile ET to be pretty consistent.

Keeping it level, and finding a level surface to run on is the biggest problem.

 

I have an extra one you can borrow and try out. If you like it, you can buy it cheap! I have two! :) MJ

New engine in yet? The GTech only works if the engine is in the car! :lol:

The G-tech Pro is okay. I actually got it level once and when I had my customized '80 VW Rabbit, it hit 0.97 lateral G's. Didn't surprise me any, I knew the suspension was tough, but I think that was a little high.

The one replacing the G-T. P. is called the G-Tech Pro Comp. Point your browser over to http://www.gtechpro.com and look at it. They're definitely taking steps in the right direction. It even includes a serial interface to connect to a PC. Sounds like some fun times with a laptop in the passenger seat :D

 

Don't own one, so this is just my $0.02...

G-Tech's argument for the high 1/4 speed is that it takes the ACTUAL speed at the 1/4 mile mark rather than the last 60' average the track records.

Since it's more than a hour away to the closest track, I was thinking on picking one up too, so thanks to all who have commented :thumbs:

Yep. I understand that argument. The Vericom I have does the same thing...but its not as bad. The Vericom is typically 1-2mph higher than what you'd get at the track and on the same car, I've seen a G-tech be 3-4mph high.

One thing neither do is account for "roll out" that you will get at the track if you stage shallow. So, depending upon the accuracy of the unit, your ET may actually be a tick or two slower than what you'd get at the track.

 

I've got the original G-Tech.
Truthfully, I have used it only a couple of times.
Its kinda busy around my neighborhood, so I can't just stop in the middle of a road, zero-out the g-tech, and then run her to 60 or a 1/4 mile. Unless its 3 am, of course.
But who's neighbors will let them tune their carb at 3 am ??

I had problems with the suction cup that came with. You guys SHOULDN'T have that problem with the new unit...
I made a 1.5" x 2" square of plastic, epoxied the g-tech mount to the plastic, and then used this fastening tape my ol' man got from scotch (it resembles heavy duty velcro, but with stiff bristles on both instead of one being soft --the same tape that comes with your I-pass).
I put the tape under the winshield washer switch, by the vents, and mounted the g-tech between the gauges and the wiper switch. It keeps it out of plain view, and shades it from the sun completely, unless the tees are off.
Plus it doesn't fall off the windshield right before the end of a test anymore.

I wish I had waited another couple of weeks to buy my g-tech... I would've bought the newer one when it came out. :boxing

It looks good on paper: You know when you change jets, floor it, go thru the gears, and you can't tell if its faster than before, NOW with a G-tech, you can truly measure the differance in performance.
But you really have to either have a deserted road where you can fiddle with the g-tech, or a passenger to fiddle for you, and write down numbers for you. Of course, the New Model probably has a memory functon that allows you to recall the numbers.

Another thing, I heard a rumor that in some states, if you get caught speeding with a measuring device like a g-tech, they will nail you for drag racing instead of just speeding.
