I'm using a XGPS150A with racechrono for motorbike trackdays.
The problem is my curves are very smooth compared to my friend's curves.
I feel like this GPS module is interpoling (?) from 1Hz to 5Hz and creating this smoothing (I do not get the right top speeds, and i feel like the speed in curves is not right too. The speed should go down instantly when I cut the gas and grab the brakes but it just shows this smooth edge with wrong max speed.
To picture this, look at this comparison, the guy in blue is going 2 seconds SLOWER than me, but it feels like he's faster than me (red) everywherehttp://reho.st/view/self/04bdfeabbf7befe26aba9390342688c2ee2876fb.png
Top top this up, i cannot seem to do the firmware upgrade (the software freezess when updating) which should get me a 5Hz output (Racechrono says its 5Hz already, so is it firmware updated already ? I have no way to verify :@ )
Anyone having the same issues ?
