Bro you going to the track Bro? Yeah Bro I'm going to the track man. I'm gonna do some
laps get some video it's gonna be pretty rad. Oh cool man,
nice video! You know how fast you we're going? Uhmm...You know how many G's you were pulling? Nahhh
You know what gear you're even in? I think it's about third...maybe
all right so how do you go about making your videos look a little bit more
badass Harry's lap timer that's how there's three editions of it you get
rookie, petrol head or Grand Prix petrol head is the minimum one you want if
you're going to be doing video Grand Prix gives you everything that the
petrol head Edition does but you get multi cam support and you get support
for professional sensors which just means you get a quicker refresh rate on
your data logging on because race car driver
anyway if you can't decide which one you want you can start with petrol head and
you can upgrade to the Grand Prix edition later for just a few bucks more
you don't have to rebuy the whole Grand Prix edition I'm running this on an
iPhone 4s which is good for cine 720p video I've just basically removed
all the data from the phone so it's good for about a try a full track day even a
little bit more of 720p video this is now asking me about Bluetooth
accessories which I will cover in the second video this video we're just going
to go over the capabilities of Harry Harry's app and the next video I'm going
to show you how to hook up all kinds of other accessories to it to get the most
out of your data and video so let's get in here this is the main screen you the
first place that you would go is prepare race and here you can define your user
so define I'm the one that's driving and this is the vehicle that I will be
driving simple go in here and you can load track and Harry's lap timer has a
bunch of different tracks from all over the world right now we're sorted by the
ones that are near me since we're in New Jersey here we got Monticello New Jersey
Motorsports Park we got Raceway Park and Pocono Raceway
etc so it's kind of neat you can also go into all and see all the different
tracks all over the world they've got ones in Africa Asia you know Germany
whole shebang it's pretty pretty expansive in that department so what you
do is you would pick your lap there and you would load it up we're getting more
detail that in the second video you can do auto cross with it I've never
that so I can't really advise on how it works
new track is also if you wanted to find a new track you could define the
start/stop the corners the straightaways things like that it's if you want to set
up a whole new track and then you can actually submit that data to Harry's for
inclusion in the database and then you would be able to load that track later
ok the race option over here we'll get into that in the second video this is
where you land when you're at your track gain you want to start recording things
you can see a lot of different information from here but we'll leave
that for the second video we really want to get into here is the analysis portion
this is the meat of what this video will be about so if you're anything like me
you've probably recorded video for on a GoPro I used to do it on even like a
handycam that I had strapped down to the backseat of the car but where you get
cool video you don't really get a whole lot of information about if you want to
know your lap time you got to go back and with the stopwatch and time your
laps or you know read the counter off of the video it's not it's just it's very
tedious and you can't do it real-time you can't do it while you're at the
track you got to go home and dump all the data and it just takes a long time
this is where Harry's really shines so let's get into the lap lists here you
can see I had a couple of days worth of track events at thunderbolt and
lightning at new jersey motorsports park here right now we're just looking at
every lap that was done just kind of sorted grossly by what track it was on
this is covering multiple sessions multiple days etc we can go up at the
top here we can sort by track you can see that I got 62 total laps at
lightning on this phone 70 at thunderbolt and it's broken up by days
here November 5th November 6 we can go into session you can see at Lightning on
June 17th between 902 and 929 into 15 laps that's just a nice way to find your
data when you want it you can go by year to it as well so we're going to go over
to track here they have what these what they call these certified tracks
that's where you can go in and it's not let me refresh it there we go you can go
in these certified track sets here and these are times that people have
submitted and it's kind of like a leaderboard see where you fall so you
know I try not to look in here too often because it just proves how slow I am and
I don't want to be slow and depressed so it is it an option it is there if you
want to take a look at it apparently it's verified somehow to make sure that
you're not submitting fake times I don't know how exactly they do that but take
it for what it's worth all right so from within the analysis here we can go in
and say let's pick this day and you can see all the different sessions that we
had all the different laps and I will just pick one of these right here we're
going to go with this one right here so when you open this up you get the date
you get the time you get how this was done with automatic recording which is
really nice feature you set it up and the phone uses GPS to know where the
start/finish line of the track is you don't have to touch anything once you're
going you just let it run it's got the track it's got the vehicle it's got the
lap number you can do to put this edge of status right to Facebook you could
tweet it etc so then we also have down here a really nice thing is we have the
video from this particular lap you don't have to do any editing or do anything
you can just go and sit hit play and it'll bring up the video from that lap
already cut and even with the data overlay already going sorry I can't put
it in a landscape mode my screen capture program will not let me do that but
right away you can go take a look at it you don't have to do any processing
later it's so you know exactly what your lap time was you can go down here into
the data recording area it's got a heat map of through lateral G's around the
track you can open that up you can see all the turns numbered you can see the
start finish you can go into charts you you can see your speed as opposed to
your position on the track which is quite quite nice you can see your
overall G on this scatter diagram here they have lateral G's at different
points on the track hip lineal acceleration with different points on
the track and they actually have your elevation at different points on the
track so there's a lot of data here if you want to sort through it then you can
go into this is this area which is the times for all of the laps right now we
have all laps on I think this is Thunderbolt that I chose and you can see
here they're all listed you can zoom in on them and all of your lap times are
listed below at 224 148 146 there's a six minute lap in there that must've
been a cool down or something happen on track but what's nice about this though
is that you can open up this little key over here and it will tell you exactly
what was going on at that are in this data so Green is the absolute fastest
sector or lap blue is the fastest sector or lap at the time recorded it does a
virtual best lap which means it takes all of your best sections even if it's
from different laps and puts it together to say theoretically what you would run
if you ran a perfect lap from all from the combination of your best ones and
then the red one is just the one that you've selected so you can see here on
this lap right out of all the laps I ever ran that are on this phone this lap
right here I had the best I believe that's the best third session a third
section of the course the best first section there the second section there
and this is my best virtual lap all the way over here on the right you can see
it was a 1 to 143 that was if I combined all those other perfect sections into
that still pretty slow so anyway this is all the laps you can go up here and you
can filter it by season you can filter it by the days you go by day is probably
what we really want so November 6th here you can see all the laps from that day
just take a look and compare what was going on so now the nice thing is you
say okay wow it's really fast on this lap right here this is my fastest lap I
want to go back to that and see exactly what I did what did I do different on
that lap they made me faster so you can go into details you're right back at the
screen that we looked at before and then you go right down to your video and you
watch your video and you say oh and that lap I braked a little bit later or you
know I tried this corner entry a little bit different so with all this kind of
data here you can if you start to analyze it and come up with a method of
using it you could really start to improve your lap times so what I like to
do is is when I'm at the track I'll take a couple laps and then I'll try to find
an instructor to get in the car with me and run the laps again and generally
when I have an instructor in the car I'm a lot faster so then I can go back and
use those specific laps and look at the data and compare it to some of the laps
that I didn't have an instructor to see you know what was being done differently
and that's how you say I get faster so that's it I mean you get all of this
kind of information from a 20-dollar app so yeah I mean this is I don't know a
couple thousand dollars worth of timing equipment you're not too long ago um get
more data than you can shake a stick at you can see your average speed you can
see your max speed for that lap see the length of the track to 0.167 miles your
altitude change you know you can you can export all of this data which is really
nice you can just take this and you can put it in the drop box or you can put it
into an email to send to yourself you can render the videos right away from in
here so say you have something really cool happen like there's a spin-out or
you know you you passed a Ferrari and you want to show everybody you can
export the video by hitting this export button and it will go right into your
camera roll and then from there you can go right up to Facebook or whatever
wherever you want to put it essentially without doing anything you just get out
of the car go find that lap hit export send it up and you're good five ten
minutes after it happened you can also this little Google Earth
option which is kind of cool you pull it up
I'll show you guys since I installed Google Earth for it alright just let it
load here for a second
iPhone 4s is not the quickest thing out there all right we're doing this little
fly in here and it's just giving you the data track and the heat bet as GPS heat
map overlaid on a satellite image which is kind of cool alright well that does
it for part 1 of this series in the second part I'll show you how to overlay
some additional data points such as throttle position rpm and your what gear
you're in also we'll cover some of the external hardware that we use an obd2
sensor that's either Bluetooth or Wi-Fi to interface with the phone to get some
additional data so if you liked this video or if you want to be notified of
