Some of you may already have heard of the SJ4000 . For those who don't, it's a quite cheap alternative to the GoPro.
With only ~90€ for the WiFi version, including various accessories and an additional battery pack it comes in handy for those of us who don't want to pay upwards of 400€ for a cam +...

Our club has recently changed the way we enter the track so we don't get to cross the start/finish line before the race starts, this means that the lap timer does not start or connect to the external camera until after I cross the start finish line after the race start. Is there a way to change...

Not sure if this is a bug but start speed currently jumps from 0mph to 19mph (30 kph) but 1 mph increments would be nice. Specifically, I would like to do a rolling start from 5mph to 60mph.

Love Laptimer.
The updates make even better every time. Keep up the great work!!!!
With the new Iphone 7+ having 2 camera lenses, will their be a way to select which one is used? I know with the phone not being available yet its probably to early to know how its going to work.

I would like to have...

I'd like to request the ability to select an audio source for a multicam overlay during export. Perhaps a checkbox next to the video thumbnail that allows the user to select the audio channel from that video for the overlayed and exported video. Naturally, the default would have audio selected from...

I've struggled with using my HLT when doing autocross. If I manually start the video to avoid the 1-2 second video startup delay when HLT senses me crossing the start line, then my timing for the run is totally off (manual start/stop as opposed to automatic POI driven start/stop). As each run is...

I find that the smoothing I need is near the far right of the scale and the adjustment is way too fiddly for my fat fingers. Plus and minus buttons or some other form of fine adjustment that doesn't change when you take your finger off the screen would help a lot.

I've thought of a possible way to...

Hi,

Correction of the inaccurate triggers for the Nordschleife BTG track set has been requested previously however I understand that modifying the existing track set would render the extensive lap library on Harry's server unusable. e.g. no data points to pad the last couple of seconds of the lap....

Hi Harry,

This looks like a cool affordable all in one hardware to the HLT.

would it be possible to have this supported by the app in the near future?

Thank you!
Scott

I have an iPhone 6 that is capable of 60fps video, and I have enabled the use high FPS setting in HLT but it does not work.
I believe this is a work in progress, but I wanted to request this addition as well.

Thank you.

All I need is the mph... we are using the vbox sport for offshore boat racing and the was told to down load Harrys Lap timer to read the unit and give me live data as I dont have a iPhone.

Problem is the data give is so small I'm unable to read it at speed ... can you make it any larger? :?:

I love LapTimer and find it very useful. The following are just observations I've had over the course of using it to analyze my data.

1) Often when reviewing a lap that has video, the video display blocks the "car triangle" showing my position on the track map. It would be great to be...

Hello,
I am racing motorcycles and would like to have access to the "real" angle of the bike (not the one calculated from the GPS).

I found the sensortag from TI ( ) very interesting for this and it is already integrated into the Camper version.
I would not mind putting this directly on...

Hi,

When overlaying multiple laps, it would be nice to have the current best show during the video overlay. You have to pause the video or slow it down when cross start/finish trigger to know the lap times.

For example:
I want to over lay 4 laps:
01:38.57 lap 1
01:33.42 lap 2
01:37.56 lap 3...

Hi Harry,

I'm using an external 5 Hz GPS tracker and my car delivers unfortunately only 1 Hz OBD data (not a too old-fashioned car - a 2009 BMW Z4 Coupé ... however, no CAN Bus yet).

I assume that HLT is aligning all data according to the GPS data interval.For the lap data files, this means that...

I noticed in the "hacking" guide, we're essentially left with a list of PIDs and told "don't use anything else, it'll just get ignored"

Is there any plan for implementing custom PIDs? I would love to just use my Arduino to pull brake pressure (for example) off of CAN, and then...

I keep a spreadsheet of corner entry speeds, speeds at the end of the following straights and anything else of interest. I then analyze how my best laps compare. On my last DE, I actually improved my previous outing on this track by 5 seconds, from 2'14" to 2'9". That's a lot, but when I...

Since apple doesn't provide the capability can you add option to lock orientation? Since CarPlay is not allowed I connect my phone via hdmi and output to my screen(added a bypass for displaying video). Works good until CarPlay is added but my phone is in glove box and can switch orientation which...

I had all sorts of trouble with auto start video with hero 4 session. Can you please add a test option where it cycles thru its start stop video recording logic to verify it communicates and works properly. I would check before entering track that it was connected and then get back in and nothing....

Here are a couple of features I would find handy...

1. OBD data collection options - would be nice to collect only PIDs for overlay screen in a single option instead of creating a long exclusion list. Maybe a couple of levels with the second including PIDs used in analysis and a full setting as it...

Please develop a Race/Speedo view with three large digits, as opposed to an analog dial with three small digits. Also a landscape mode with even larger digits. Would like to record lap time data in the background while being able to glance at GPS speed from VBOX Sport. Thank you

When reading the following article it seems there is some confusion about what data is overlayed on the map...

The author says the red/yellow/green overlay shows longitudinal and lateral g's. Unless I misunderstand myself, I thought that that overlay only shows lateral g's. When I checked the...

Hello,

In the hall of fame tab, we are allowed to sort by date or by laptime.
Would be nice to have a third option to sort by "day + laptime" : we would then be able to quickly get the laps of the current day for all users, sorted by laptime.

The list would then look like this :
laps of...

Hello,

I was thinking about a new timer view, with time fields only.

Here it is :

It is a gap view.
We are in lap 3, we already have won 3.32 seconds (L3 and minus sign in green), and we are still winning (green up arrow).
Sector 1 is finished, we lost 5.37 seconds in it. We are then in...

Couple of features I would love to see.......sorry if they exist already ?

Using the data collected the ability to display a Motec / Race Technology DASH2 type of display on the screen, this would make using a device to permanently replace std gauges in race cars and kit cars a viable option ?...
