59 G-TECH/Pro SS/RR Fanatic Manual
But there are several things you should know about SD cards and file system. There are many devices capable of using
and formatting SD cards, like personal computers, mobile phones, cameras, camcorders, etc. Formatting includes creating
complex structures and setting several parameters which compose file system. Because of that, there are some
differences between formatting on various devices. Some devices will format cards using FAT16 or FAT32 file system.
They can also use different cluster sizes to suit their needs.
To ensure best performance, format your card using G-TECH. This will set appropriate file system and cluster size to
optimize file system operations.

About Vehicle Weight
In order to calculate meaningful horsepower measurements, you must provide an accurate value for your vehicle’s
weight.
In this manual, the term “vehicle weight” refers to all the weight that is supported by the vehicle’s tires (including the
tires themselves). So this includes the driver’s body weight, fuel weight, tools, fast food wrappers, etc.
If you are fortunate enough to have access to an accurate vehicle scale, go ahead and weight the vehicle as it would be
equipped at the track (i.e., with you in it, the correct amount and type of fuel in the tank, etc.).
Some tracks even have scales available for weighting your vehicle. Also, some towns have dumps or refuse collection
areas with large scales that you may be able to use. Moving companies may have vehicle scales as well.
If you can’t weight your vehicle, estimate it. Use the manufacturer’s data to obtain vehicle weight (from the Owner’s
Manual or the internet). Then adjust the weight based on the difference between your car as it was stock, and as it is now
(Have you added heavier stereo? Have you removed the spare tire?). Don’t forget to include your own body weight and
the fuel as well.
You do
NOT
want to use the Gross Vehicle Weight Rating (
GVWR
) value that is provided in the vehicle door jamb as the
actual vehicle weight.
GVWR
is the fully-loaded vehicle weight with passengers. Thus,
GVWR
is always higher than actual vehicle weight, and if
you enter
GVWR
instead of actual vehicle weight, your horsepower numbers will be artificially inflated.
A rough rule of thumb to estimate your vehicle weight from the
GVWR
exists, but don’t rely on it being too accurate.
Again, this is very ROUGH rule of thumb… each manufacturer calculates
GVWR
in its own way…
The rule of thumb is to take the passenger capacity of the vehicle (e.g., 5 for a mid-sized sedan) and subtract from the
GVWR
180lbs for each missing person.
Example: Suppose
GVWR
= 4200 lbs, vehicle capacity is 5 people, but we have only a driver. Thus there are 4 missing
passengers, which means we subtract 4x180 lbs. The value 4200 lbs – 720 lbs = 3480 lbs. Thus you would enter 3480 lbs
into the G-TECH for vehicle weight.
