instant Gforce measure for:
Acceleration/brake (brake is negative)
left/right (left is negative)
Up/Down(up is negative)
Total (always positive)
Test your time from 0 to whatever you chose
(it uses gforce to start the timer)
Max Values (i know it needs work)
Chose what you want to log
Set update speed 50 - 1000ms
Use Km over miles per hour
Use Speed in Acc/Brake over Gforce in Main
You can get the gflog.txt in you main memory and open in excel
To clean the log just delete it.
X is left/right
y is acc/brake
z is up/down
t is total
(all this are obvious)
the GFmax is store in gfmax.txt created in main memory.
How to use it correctly:
the pda must be in portrait whit the screen facing the back of the car. When you open the program it will self calibrate(this don't mean you don't need to have your acc calibrated whit other program).
It should read 0.00 whit the car stop in a level area. You can Turn or incline the PDA a little and calibrate again but it will affect the reading if too much off center.
