Video delay, G Level, and Tachometer questions
Posted: Sun Jul 12, 2020 4:23 pm
Hi Harry,
I’ve been enjoying using HLT for several seasons to record video during track days and most of it works great but a few things don’t work so well. I’ve worked thru many settings but still no luck with the issues below, maybe you can help me with the settings that will improve these issues?
I’m using:
HLT version 23.0.11
iPhone XR with 64 GB of memory and iOS 13.5.1
Go Point BT1 OBDII with version 177.0.7 firmware
(1) The main annoyance is that the video lags the overlaid parameter graphics by ~2 seconds all the time. So when the overlaid graphics show the RPM decreasing and the brakes being applied coming into a turn, the video and audio show that I’m still on the throttle accelerating towards the end of the straight. I’ve worked thru the Fixing Video/Data Alignment forum post and got one session to match pretty well. Does every recorded session have to be adjusted like this, or does HLT now remember those settings for future sessions?
(2) The G level indicator always defaults to 1.0 G (at the 9 o’clock position on the outer circle) and just sits there. I have the ACCELERATION Calibration setting set to ‘Cam Preset’ so that it should read zero with the phone mounted horizontally looking forward thru the windshield. I can get it read zero correctly when the phone is in my hand and being held horizontally, but when I record a run it always goes back to 1.0 G. Any suggestions on this?
(3) The RPM digital display appears to be correct, but the green & red ‘tachometer’ display is not scaled right. At idle, the needle is halfway up the green band, and at 5000 RPM the needle is deep into the red zone, even though I have max RPM set at 7300 on the Vehicle #1 page. Is there a way to set the scale properly on the ’tachometer’?
Thanks for your help!
