Introduction
The G-Analyst is an OEM-grade precision vehicle performance testing system designed
exclusively for your Bluetooth Palm handheld.
Installation
Using the included Velcro, install and orient your G-Analyst as shown in Figure 1. The
unit should be placed on a relativelyflat and level surface and firmly anchored. The
battery-door should be down and the power switch should point to the rear of the
vehicle.
Some mounting locations may include: the dash, the floor, the inside of the center
console, etc. It is also important that your G-Analyst unit point straight ahead; otherwise,
accuracy will be reduced.

Entering the Calibration Settings
Before you begin using your g-Analyst, you will need
to enter the calibration information.
1. From the 'Home' menu (See Figure 2), tap 'Calibrate'
2. You will need to enter calibration information for the
1.5G/2.0G/4.0G/6.0G ranges (See Figure 3). The
calibration information was provided with you g-Analyst.
3. Hit ‘Next’ to move to the next page of calibration
information.
4. When you are finished entering the calibration
information on the 6.0G page, hit ‘Next’ to return to the
‘Home’ menu.
Figure 3
Figure 2

14
Entering Your Vehicle Information
1. From the 'Home' menu (See Figure 2), tap 'Vehicle Info.'
2. Enter the text that you would like saved with each vehicle
test. See Figure 4.
3. Enter the vehicle weight.
4. Tap 'OK.'
Note: You can keep track of your testing and tuning changes by
updating this screen between tests. For example, for the first test,
your text could read: "Base line testing. East-bound." For the
next test, your text could read: "Base line testing. West-bound."
Note: An accurate weight is essential to obtain good results from
the estimated ¼ Mile calculations and the horsepower
calculations. Have your vehicle weighed at a public scale if
possible. If not, your vehicle weight can be estimated by using
the certification weight of your vehicle (see Figure 5). This
weight number is usually found in the door jam of either the
driver’s or passenger’s door. Take the certification weight and
subtract (180 lbs. * rated number of passengers), then add in your weight and the weight of any
cargo. This should give a reasonable approximation of your test weight.

Test Options
Speed Testing
The ‘Speed’selection will test the performance of your vehicle to any speed that you
desire (MPH or KPH). If you choose the default (60 MPH), you will also receive an
estimate of your ¼ Mile performance and horsepower. This is done by using the weight
of your vehicle, the acceleration characteristics, and a proprietary algorithm.
To begin testing:
If you haven’t selected your test criteria, then do Step 1)
and Step 2). If you have previously selected your criteria,
then proceed to Step 2).
Step 1)
From the 'Home' menu, select the Palm menu icon, the
‘Settings’, and then ‘General/Time to Speed.’ See Figure6.
You may change any of the selections in Figure7.
However, it is recommended that you not enter a Start_G
value of less than 0.30g unless you are having trouble
getting the test to start on initial acceleration. See
Appendix 1 for a Trouble Shooting guide. See Appendix 2
for a Speed Testing flow chart .
Figure 6
Figure 7

16
The next window you will see is the 'Acceleration' window
(see Figure 8). The reading displayed is the current g-value
that the G-Analyst is reading. If the G-Analyst is mounted
slightly nose-down, then the reading is in negative g's. If
the G-Analyst is mounted slightly nose-up, then the reading
is in positive g's.
When you are ready to test, tap the 'OK' button. TheG-
Analyst will begin a short calibration procedure. When the
unit is finished calibrating, you will hear a beep (make sure
your system sound is turned on!) and GO! will be displayed
on the screen. If you receive a ‘Tilt’ error, then you need to
reposition the unit andtry again.
Start accelerating (theG-Analyst will not start without you!).
The progress bar will fill with the increase in your speed.
A beep will sound when the test is complete. The results
will be displayed (See Figure 9) along with the option of
‘Graph’ or ‘Exit.’
If you choose ‘Exit,’ you will return to the ‘Home’ screen. If
you choose ‘Graph,’ you will have the option of reviewing
your results graphically. Please see the Graphing section
for more details.

17
Distance Testing
The ‘Distance’ selection will test the performance of your vehicle to any distance that
you desire (feet or meters).
To begin testing:
If you haven’t selected your test criteria, then do Step 1) and Step 2). If you have
previously selected your criteria, then proceed toStep 2).
Step 1)
From the 'Home' menu, select the Palm menu icon, the ‘Settings’, and then‘Time To
Distance.’ See Figure 6.
You may change any of the selections in Figure 10.
Note: This test uses the Start_G, Start_Speed,
Start_Distance, and Time_out values shown in Figure 10. It
is recommended that you not enter a Start_G value of less
than 0.30g unless you are having trouble getting the test to
start on initial acceleration. See Appendix 1 for a Trouble
Shooting guide. See Appendix 3 for a Distance Testing
flow chart.

Brake Testing
The ‘Brake’ selection will test the braking performance of your vehicle.
To begin testing:
If you haven’t selected your test criteria, then do Step 1) and Step 2). If you have
previously selected your criteria, then proceed to Step 2).
Step 1)
From the 'Home' menu, select the Palm menu icon, the
‘Settings’, and then ‘Braking.’ See Figure 6.
You may change any of the selections in Figure 12. The
Brake_Speed is the speed that you must reach before you
are prompted to begin braking. The Stop_Speed allows
you to adjust the speed at which the test is stopped.
Note: It is recommended that you not enter a Start_G value
of less than 0.30g unless you are having trouble getting the
test to start on initial acceleration. See Appendix 1 for a
Trouble Shooting guide. See Appendix 4 for a Brake
Testing flow chart.
