hmm - i did try a phone reboot between sessions on sunday but it didn't change the behavior...

saturday morning - in between session i did export a couple of laps with overlay.

I've been trying to run down this problem for a long time now, with no success and i'm curious what others have done to fix this. i'm using an iphone 8+, and now with a racebox mini external gps. i'm using the internal camera on the phone only. what i've noticed is through several versions of harry'...

This past weekend at the track - Harry's worked fine Saturday, with a few issues - but, for the moment this is a bigger issue. On Sunday, every time I crossed start/finish on my out lap out of the grid, the video would freeze. laps seemed to be recorded, minus video. it did this every session i drov...

so, after doing some more review of my videos - this might have come into notice when i switched from an older dual gps to badelf...

any settings i should check or tweak in laptimer or elsewhere that might have caused this?

harry - one last question...i know this is going way off topic, and i apologize. but, curious - do you know of any way to get data from a '95 BMW M3 (OBD 1) car into laptimer other than gps, etc?

yes - understood....went through that type of thing recently with my triple screens for simracing.... i may try the calculated next time around and see if that helps. it's definitely enough out of sync that its easily noticed....i would think my setup is simple enough - the phone is only used for th...

harry - yeah, good point. i can tolerate a bit off sync due to doppler as you mentioned. it's just nice if i can get it closer. that's how i ended up at asking about the gps delay in the settings. it's set at .7 (i did not set that) - and was curious if there was a known good range for badelf or if ...

i think its all laps - actually. the video/audio sound fine, everything else looks to be in sync - timing, track location, g-force, etc. it's the displayed speed that is off. i think the speed is right, but the timing is not. i need to try and figure out is the sync ahead or behind - my honest feeli...

i forgot to add:

i'm using an iphone 8+ and its internal camera only, with the lightning connector bad elf gps. so, not a complicated setup. the phone is mounted to my windshield and seems to get good gps coverage.

hi harry! thank you for the quick reply! i think all of my laps are showing the same issue. so after looking at the adjustment steps that's how i got curious about the sensor delay itself. it also seems to perhaps start being a problem on a specific part of the lap, but, i haven't confirmed that yet...
