1998 BMW M3, iPhone 6 and Go Point BT1.
BT1 is installed in car and connected to iPhone.
BT1 does not show up on sensor list in Harry.
How can I get Harry to recognize the BT1?

Hi Harry and everybody at the forum !

I'm a recent user of HLT and I used it a few days ago on track (circuit de la bresse, France).
It is linked to an obdlink MX and i made the video with my honor5C android smartphone (+ other cams inside and outside the car).

I've runned some tests last week...

Last weekend I was at the Lausitzring, supporting a friend during the German Time Attack masters. Therefore I was checking his lap times from pit lane and during the whole day the update rate started dropping to 0 every lets say 30 seconds and simply not recovering. I had to either enter the hall...

I purchased a more expensive GoPoint unit and it just stopped working after just a few months. I am frustrated with spending more on what is likely the exact same thing as the cheaper units. Does anyone know of a reliable ELM327 unit that works with an iPhone or iOS and Harry's Laptimer?

I am using an iPhone 7 with a SkyPro XGPS160 GPS Receiver. When I import the data into a mapping image it shows that it's off track. This has also showed that my distance traveled is extremely long compare to the length of the track.

Are the map overlays suppose to be more accurate than this?

I received my new RaceCapture module today. I plugged it into the car and connected the WiFi to my iPhone. HLT doesn't see it. I think I need to specify the TCP port for the RaceCapture/Pro WiFi Bridge, but I can't find what that's supposed to be.

I recently bought a Kiwi3 OBD2 dongle to replace my OBDlink MX Wifi. The MX was having constant connection issues, primarily in the vicinity of mobile network towers. It also seems to affect the overall update rate of the XGPS160 fixes.

Problem: Although the Kiwi3 connects and communicates...

having have the trial version a couple of years ago i upgraded 2 days ago to the petrolhead version off play store.

i was at oulton park yesterday it was only recording 3 laps at a time(annoying when slicks take 2 laps to warm up).. so i upgraded again to grand prix version thinking it would give...

Did a few overlays and the track map for Watkins Glen rendered in is a very odd spot. Any thoughts?

Take a look:

Hello. I have established a Wi-Fi connection between HLT and a Garmin VIRB Ultra 30 with the "external cam only" option chosen in HLT. GPS is "on" and receiving for the VIRB. I have also chosen Admin/Settings/Multicam Control/External Cam = Garmin VIRB. However, the VIRB does...

I have recently started getting this error repeatedly while using HLT around my local area and to and from work.

Warning: Unexpected, video recording has ended (Cannot Complete Action).
Laptimer will try to start video recording for the next lap again.

I have had this in the past, but only...

This is on android and using sony cam, so I can't say if it affects iOS or gopro.

External cam start/stop over wifi works when I have internal cam + external cam set up to record from the Timer screen. If I select external cam only (which is what i tried to use the other day), the wifi start/stop...

Version 21.0 - just updated yesterday
GP version - worked previously last fall
iPhone 6 - iOS 10.2.1

App crashes shuts off when I go to download a track specifically when I go to the confirmation and try to click on "proceed". App closes.

So Ive exported the files from Harrys to csv etc and got them on my PC alongside GoPro videos triggered seperatly.

Im trying to overlay them both within RaceRender. The laps were 6-8 per session. I can sync 2-3 then it goes out by 5 plus seconds at some point and gradually looses all sync.

Ive...

Hi Harry,

Grand Prix Edition

I went to 2 race tracks on my motorcycle recently and my iPhone 5 could not get the GoPro to start. I checked that the password in the app is set correctly as I know this is the most common reason for this failure.

I used a GoPro 3 Silver.

One thing I noticed was...

Only my second track weekend and 2nd time using Harry's laptimer...
Was able to successfully overlay complete 20min sessions first time, but ran into a bit of a snag

I first used gopro video files directly from gopro SD card. Problem is that the video was actually segmented into multiple files, so...

Twice today, multiple laps were recorded and combined into one lap. Is it possible, how to split the data into the individual laps to allow for analysis and overlay onto the cell phone video? The video recorded fine, its either 8 or 9 laps that the lap list shows as three laps.

How to avoid the...

hi again harry
i am having a very difficult time to synchronizing my gopro files with the data directly on my android phone.
Its never sync properly.
Could you pelase explain a way to export the overlay only (speed gaches / track position etc..) so i can use it as a layer on my video editing...

Hello again,
I have laps on my Racechrono unit I'd like to import into HLT. I've tried exporting them in the Racechrono, then using my Mac find the export files on the Racechrono in finder and emailing them to myself. For VBO files when HLT tries to open I get a failed to import message in HLT. For...

hi Harrry,
Since a couple of weeks (after probably an update)
each time i conntect the app to my gopro 4 black the FOV settings is changed automatically to Medium
This is quite annoying could you please look into it?

I've got the RaceCapture/Track from their Kickstarter campaign, and have it configured according to this thread:

I have everything set to 10Hz, the GPS, and also the two OBD channels (RPM and TPS). All of the Accelerometers, telemetry, etc are disable according to that thread.

If I open up HLT...

Hi All,

First time poster but longtime user of Grandprix (purely for timing purposes).

This weekend I linked my GoPro to my Android phone OK and did some laps. I'm now trying to overlay the data onto the video but when I go into the Laplist and choose the lap I want and go to Video; it just says...

This happened approximately five times during 198 laps in two days, I had HLT's on GAP mode during lap. Typically, I will see plus/minus 3 seconds during a lap. For 5 Instances, lasting about 10 seconds the display showed a gap amount of over one hour,, e.g. 1:27:50:xx then reverted back to the...

Hello,
I have a Droid DNA that does not have an external memory slot. What I do have is a dongle that connects to the data port on the bottom of the phone that connects to a 64gb thumb drive. The device recognizes the drive as well as other application but Lap Timer does not. I've re-booted,...
