I've been using HLT for a couple of years now on Android with a Qstarz 818XT gps running at 5 & 10 hz. The last 2 times (December and this weekend) I notice the following issue:

If I run HLT with no external GPS, I get gforces recorded and displayed in the video feedback and on the map

If I...

If I am using a GoPro for example, do I have to start recording by pressing the record button on the GoPro or can the recording be started from the phone itself.

What video device is best to use for best video syncing with data recording? I assume the app the connect to multiple sensors right? One...

Good evening Mr. Harry

I would like a new benchmark

I want to know the update rate of each company OBD 2

1
BAFX Products Veepeak etc. Low cost and popular items
Is the update rate still slow?

2
TONWON BTLE OBDLink Kiwi 3
How much is this BT update rate of this 5 star compared with OBDLink MX?...

I'm running HLT on iPhone 7, Kiwi3 OBD, Hero 5. When I start a session, all is good. Strong WiFI connection, green and blue dots blinking on Camera icon in Timer view, etc. HLT records about 10 minutes of video data (4 or 5 laps), then I assume the WiFi connection drops while I am still driving....

I have Petrolhead with an iPhone 8. Since upgrading to the iPhone 8, my data overlays have been out of sync with the video. Any ideas or things I should troubleshoot? I think it is due to the new phone but I’m not positive. I never had this issue before the new phone.

Thanks

Hi All/Harry,

Have a track day coming up and trying to get the app sorted with my e60 (07) BMW 550i. I purchased the app for iphone as well as the kiwi 3 obd dongle. A couple issues I'm having.
1. There is no Throttle information coming through (as well as temperature, hp etc) however the rpms do...

How do I get the Guide Screen to appear? Whenever I restart HLT, it opens to the Home Screen.

First time user with Petrol Head Edition, see the video on my phone and then did the overlay. After overlay is complete get message that overlaid video can be accessed from Lap Details and and using the Photo App but am not having any luck finding either of these in the app?

Also where can I find...

Does the app Bluetooth support heart rate monitor?

Since all new iPhones have a wobbling lens in the main camera I meanwhile use your phantastic app with the selfie front camera. This selfie camera is of a sufficient quality, but has no wobbling lens. I am happy with that solution.

When watching the video with the overlay, however, the G-Force...

I am trying to get the following setup running and I am having some issues with the multi camera:

Phone: Nexus 5X running Android 8.1.0
GPS: VBox Sport
OBD: OBDLink MX WiFi
Camera: 2 x Sony FDR-X3000
Software: Harry's LapTimer GrandPrix edition

The issue I am having is that LapTimer does not find...

Good morning. I have been using Harry's on my phone for years. I recently set the race car up to accommodate my Wife's ipad mini. Apple support has been telling me that I have to purchase the app a second time to have it on both devices. In the app store, it says that Harry's supports family...
