1Welcome
1.1 Thank you
I would like to take this opportunity to thank you for being who you are. You, and guys like you, are keeping car
enthusiasm alive and well.
This new G-TECH/Pro Performance Meter is based on High-Speed 10Hz GPS technology and it’s better than ever. It’s
everything I always wanted it to be, so please enjoy it.
Jovo Majstorovic
President & CEO, TESLA Electronics Inc.
1.2 About your G-TECH
Your G-TECH is built for severe vibration environment, that’s why all of the components are “floating” inside rubber
material. There is no stress-points and hard mounts anywhere on the device. G-TECH has a built-in High-Frequency GPS
antenna (square bulge in the back) which needs to be exposed to the sky. When the unit is turned on you will see the
amount of satellites currently in the view (12 maximum) in the upper right corner of the display. The more satellites G-
TECH “sees” the higher the accuracy will be. When you turn on the G-TECH it will take a few minutes to lock onto the
satellites. Look for a small plus sign between the satellite icon and the number of satellites. This indicates that SBAS
(Satellite Based Augmentation System) is locked in, this will improve accuracy. For best performance, keep the G-TECH
right on top of the dash in the bottom of the windshield. Small icon on top of the screen indicates if the MicroSD card was
inserted properly (RR model).
There are two models, SS (Super Sport) and RR (Road Racer). To upgrade from SS to RR is as simple as inserting a RR
expansion board in the back of the unit. Available at gtechpro.com
SS is intended for all of the standard straight-line performance measurements including, Horsepower, Torque, 0-60mph,
60ft times, 1/8 mile, 1/4 mile, braking distance and more. It has the capability to replay runs and can be used in all
vehicles including cars, motorcycles, boats, tanks etc.
RR model has all of the functions of the SS plus it has the ability to record lap times on the racetrack. RR is also capable of
displaying lap-segment times as you are driving. This feature will help you improve as a driver and help shave-off seconds
from your lap times.

2Basics
2.1 Front Side
Figure 1: G-TECH front side
•
MENU button – used to get you in and out of main menu and out of submenus
•
ROLLER dial – is the most important in navigating though the user interface. Please note that besides being able
to rotate up and down, it can also be pushed-in to select a given menu item.
•
SELECT button – is the part of the ROLLER dial. You can push-in the ROLLER dial and this action will be referred to
as SELECT button throughout this manual.
•
REC button – this is the record/replay button and it its used to let G-TECH know that you want to start a SS run or
a RR session recording. It’s also used to input Start/Finish line and segment gates in RR mode. Throughout this
manual, this button will be referred to simply as REC button.

2.2 Back Side
Figure 2: G-TECH back side
•12Vdc Power Port – plug in the supplied DC power cable into this connector
•Expansion Port – reserved for future use
•Switch Module Port – connect Switch Module to this port using supplied Ethernet cable
•DB9 Port – no user functions are available trough this port, used in G-TECH production and maintenance only
•MicroSD FLASH Card Slot – It uses “push in & push out” action just like a ball-point pen. Pushing it with a paper-
clip works well
•Square mounting stabilizer – Insert this stabilizer into the square hole in the mounting clip and snap it.
2.3 Accessories
•12V cigarette lighter DC Power Cable – supplies power from vehicle’s accessory (cigarette lighter) plug.
The DC Power Plug has a fuse at the end that plugs into your vehicle. If the cable does not seem to provide
power, the fuse may be blown and need replacing.
To replace the fuse, unscrew the tip and replace the fuse with a standard 1A (one ampere) fuse. Fuses can
normally be purchased at any automotive parts store.
•Mounting System – used to hold your G-TECH steady in you vehicle.
For additional details, please refer to “Mounting System” on page 11.
2.4 Icons and Navigation
The G-TECH’s functionality is accessible trough its user-friendly icon interface.
Pressing the MENU button on the Main Screen brings up the main menu, as shown below:

8G-TECH/Pro SS/RR Fanatic Manual
Figure 3: The G-TECH's Main Menu
The name of the menu appears in the Menu Title Bar at the top of the display (“Main Menu” in this example).
The main menu has 4 icons. The first icon is in “reverse video” because it is the active (selected) icon. Use the ROLL dial to
move amongst the different icons.
For example, moving the ROLL dial down by “one click” in Figure 3 would move the icon selection to the Setup icon, as
shown below:
Figure 4: Main Menu: "Setup" icon selected
The Setup Icon Hint in Figure 4 indicates that the selected icon represents setup items.
Use the SELECT button to make a selection. For example, to customize the G-TECH you would move to Setup icon and
then press SELECT button.
Selecting Exit icon on any menu brings you up one level. If you are on the Main Menu when you select Exit, you will be
returned to the Main Screen.
Figure 5: Main Menu: "Exit" icon selected
Moving one level up on any menu can also be accomplished by pressing MENU button. If you are on the Main Menu
when you press MENUbutton, you will be returned to the Main Screen. Pressing MENU button again while on Main
Screen will bring you back to Main Menu.

3Quick Setup
3.1 Connecting
There are only two cables to connect on the G-TECH unit. The Switch Module is connected to Switch Module Port by
supplied short Ethernet cable. If you want to mount the Switch Module away from G-TECH unit you can use longer
straight-trough Ethernet cable to do that. Power supply is connected trough 12VDC Power Port.
For location of Switch Module Port and 12VDC Power Port, please see the image in section 2.2 on page 7.
3.2 Adjusting Local Time
G-TECH date and time are based on Coordinated Universal Time (UTC) which is extracted from GPS signal. This time code
is closely related to Greenwich Mean Time (GMT) and it has time zones defined the same way as GMT. To obtain correct
date and time you need to adjust difference between UTC and your local time.
To access Adjust local time menu, follow the steps below:
Press MENU
button to enter
Main Menu

time
Note: This setup requires that G-TECH has a valid GPS signal in order to extract UTC date and time. If that is not the case,
you will see a screen as shown below:

Figure 6: Adjust local time - no valid GPS signal
Note: You need to be in open space for G-TECH to acquire valid GPS signal. If you are in garage, under the large bridge
or in a tunnel, please drive your car out into open.
Once G-TECH has a valid GPS signal you will be presented with this screen, where you can use ROLL button to change
displayed time until it mach your local time.
