I caused this issue myself by restoring a backup when the data was still there. I can manually delete some entries but eventually, the app crashes. In some cases upon restart the app will rebuild the databases and add back in the duplicates. The duplicates throws off the lap count.

Now, that V22 has come out my acceleration data is now working again but it is skewed about 40 degrees. I have tried the "Left Hand Traffic Preset" (since my mounting position is left of the driver) and "Automatic Preset" without success. I have been editing the CSV data and...

I have version 22.1.2 and am sitting at my desk with my phone in front of me, and Laptimer starts recording randomly. I didn't touch anything and the phone isn't moving, I'm not near any tracks. I was preparing to overlay video from my most recent weekend, but haven't started yet. Is the magic self...

Everything was great until I updated the app in mid-August. Since then the app hasn’t been correctly trigging the start/finish at autocross. Two others, that I know of, are having identical issues coinciding with the app update.

I just spent this afternoon updating to ios 12.1 and trying every...

Hi,

I'm trying to apply overlay to gopro video I have recorded.

I'm following the youtube video Harry posted on this. I get stuck on the stage where you add video to a lap using
Lap -> Edit -> Add Video

The video I want to use is not displayed on the list but the video is in the Photos...

I purchased Grand Prix a few years ago. When I recently upgraded phone from Galaxy s7 to s9plus, the version that transferred to the new phone is petrolhead and worked only for three laps per session. From what I have read, this is not registered properly. How can I get this corrected?

This has been an ongoing issue with me. When I use my Kiwi3 with my iPhone 7+ and the latest version of HLT, OBD data from the Kiwi3 seems to drops intermittently throughout the lap. You can see a demonstration of this in my video from a track day last month below. Running this setup from a 2012...

So I used the app to control my hero5 and i'm having two issues:

1. The video files are 4GB splits and so large that you can't transfer them to your iPhone. As a result how do you relink them with the lap list?

2. Some of my laps didn't register as one lap but as two laps (twice around the track...

Hi,

For some reason internal camera did not recorded anything on my first session today (the second one was ok) and now I'm trying to use the video from the dashcam to use as video for my first session. I selected the end frame for the lap, the preview worked fine (with overlay) but the app is...

I upgraded my iPhone 7 to iOS 12 today. I am not sure if it is related but I got very unexpected behaviour.

I started a Recording manually at work, and drove homewards. No lap was triggered as I crossed the start finish line. I thought I must not have had my Work to Home track loaded and thought,...

Hello,

I have Harry's Laptimer Petrolhead v22.1 with ReDrive running on firmware 1.5.181. Adding the RDG_... device as a GPS sensor just shows it as "Searching" then "Not available". This happens regardless whether the ReDrive app is running in background or not. When I run the...

Laps are only recorded when I use video.
When not, nothing is recorded.

I got this message about 10% or low battery on my iPhone X in the middle of the session. Since I was in gloves I couldn’t press “ok” so the message stayed on the screen.
When I got back to pits I was amazed that only about half session was recorded. Pretty sad, cuz I set my best time of the day...

I'm running the latest version of the iOS version of the software, the one which says in the notes something about a fix when crossing N/S or E/W finish lines sometimes laps won't trip. I think it's possible we're still seeing a variation of this issue. Several times laps would fail to trip while...

Hi when I try to find a new car by searching for "Porsche" the list ends at Mini and the autocomplete doesn't match what I've typed. I do have a Mini defined if that matters. I'm trying to add the Porsche Cayman S I just bought and don't want to manually enter every field. It's been a...

Hi all,

I recorded 2 manual laps today with external GPS (5 Hz) and OBD (~1 Hz). Data was stored with interpolation to 10 Hz.

Later, I tried to do video overlays of the 2 laps. Lap #1 is perfectly fine.

Lap #2 has video overlay issue, however. - Time, Speed, Map and Acceleration are shown...

I've experienced a strange issue recently with HLT. I recorded a GoPro Hero 5 Black video of a session, with an external microphone. I uploaded the video from my iPhone Photo album directly to YouTube and everything is fine (see below):

Subsequently, I added HLT data overlay to the same video in...

Hi,

not sure whether I found a bug or whether I'm doing something wrong.

I'm trying to log my driving on e.g. Sunday drives with HLT. To do so, I turned on the manual start-stop-option in the settings menu. When I use the start button in the timer view, the clock starts to run, and I assume that...

Dear Harry,
My ELM327 BLE OBD does not work properly using v22.1.1 Harry's LapTimer Petrolhead. But it workes well with v21.1 (I only backed up this version of the app).
Using v22.1.1 the obd does not show the refresh rate but in v21.1 it shows from 6 to 10Hz as shown in the figure below (left is...

Hi Harry,

I removed the OBD speed as I rely on my GPS and do not need the extra data. It seems the values are set to 0 instead of dropping the Channel. With overlay the GPS Data is ignored, everything is fine but 0km/h throughout.

I will remove the PID exclusion for now. Can I somehow rescue my...

I'm trying to get HLT Rookie edition running on my Joying Android head unit. My first issue is that I don't believe it has an accelerometer and I get stuck on calibration so that I can't record my lap times. My issue is exactly like this post:

Is there a way to get it working in my case? I do...

Hi Harry,

since the last update i have issues with manual overlay. If I run the video, I have the overlay at maybe 1 FPS. The video itself runs normally. This way I can only guess if my video is in sync (I sync at hard turn ins).

My setup:

iPhone X at iOS 12 Release Candidate
XGPS 160 at 10Hz...

Harry,

This past weekend, I had a great track event at at track I've not been to for 6 years. Late Friday afternoon, I stopped paying attention and as a result, ran out of space on my Iphone 6s recording videos. This crashed the app (and the phone...) In the process of working to resolve the issue...

Hi!
I was reviewing lap and video data yesterday after track day on my iPhone from the app, and since reviewing I can no longer see that lap on my lap list? How might be able to retrieve this data, and video?
I did keep getting the error that I cannot view video because the converter-media is...

The app is feeling very very accurate and stable apart from the already reported Manual Timing and Video Preview issues. I'll stay away from those subjects until the next release.

In addition to the above, I have a couple of minor quality of life problems with v22.1 since a clean reinstall of the...
