BT1 and Data Rates
Posted: Mon Mar 21, 2016 6:31 pm
Hi.
Just purchased the GoPoint BT1 to use with HLT GP Edition (19.0.31). I'm also using a Dual XGPS 160. Everything works fine together, but I'd like to optimize the BT1 update rate to smooth out the tachometer/TPS overlays in video.
When I got the BT1, I did a few test drives near my house to gather some data. When I checked HLT before driving, it said the BT1 update rate was 3Hz. Here's my confusion:
When I exported and reviewed the data, it showed an average of 9.2 data points per second, with a min of 4 and max of 11. Looking at some 1-second long groups of data points where I was at full throttle, each point shows a RPM increase. Thus, unless RPM is extrapolated, it would seem that the BT1 update rate is actually much better than 3Hz.
Three questions:
1. Can someone explain what each data point in HLT actually is? Given the claimed 10Hz from the GPS and actual 9.2Hz average I achieved, it would seem the data points are based on GPS, with accelerometer and OBD data added to each. Is that correct?
2. What does the 3Hz that HLT shows for the BT1 actually mean?
3. How is OBD data applied to data points if the OBD update rate slows down? Does it just apply the same OBD data until it gets new data?
Also, most important question:
4. What settings can I change/what things can I do to increase the BT1 update rate to smooth out the video overlays?
Thanks!
