BTW Harrys Lap timer withe iphone is the bomb. I have another lap im going to try and upload.

Nice video!!
What cam and what data acq and overlay?

Tight little course...looks pretty busy but it looks like your car was handling well and you looked smooth!!

100% iphone and the Harrys lap timer app. Iphone 1080p camera, iphone gps, iphone accelerometer, And 20$ for the app - i couldnt be happier with it. The next things i will get are an add in gps module for better accuracy and an obd2 cable or bluetooth and with that harrys lap timer can pull in engine data

I had no idea. Is this the 4s? I'm holding out for the 5 to come out.

How long can you record and how do you upload the videos? Transfer them to a computer after each race?

Car looks fast.

Killer phoneware.

I have the Trackmaster app for Android but haven't used it.

cool video man I like it. Looks like I need to finally break down and get into the smart phone world.

Looks like the brakes are performing well. I assume you got them all bled out and balanced to your liking?

very nice! car looks like it was turning well. As far as the apps go, is there a droid version of the Harry's LT? Makes me wish I had the iPhone instead of the Commando droid I bought.....

Wait wait wait....

What mount did you use on the iphone? And how does it do G readings standing up? Are you using the internal mic also? MOAR DETAILZ!!!!!

:-)

I've watched the vid quite a few times now, very cool!!!

I bought this mount, but have yet to use it. It's bad ass, I like it.

Don't even bother. If yours is anything like my X, you'll get done with a run to find that your Droid has been locked up the entire time. Iphone's work like they should, all the time. Droid, not so much. Mine gets shut down and restarted every single day.

I wonder if you can record with a GoPro but still use the Iphone for GPS and an overlay.

The app website says that it has been done successfully. I don't quite understand it, but I'm no whiz with video. Seems you need to sync the video with ITunes, then align the Lap Timer data with the video. There a bunch of good stuff here - it's a well developed site. Overlaying it on a 30-minute GoPro vid would be great.

A vid from the first session today:
http://www.youtube.com/watch?v=xlpHgX1l2Mw

I downloaded this in hi-def which requires wifi which i didnt have at the track.

Day 2 I moved up to group 1 with the 'fast guys' and open passing = big fun. Unfortunately i goofed and didnt get anymore recordings the rest of the day which is unfortunate b/c i probable had some faster laps. Oh well im happy with a 1:27:xx, a car that didnt have any major problems and great weather.

I also met Tyler Wilson here from the board, great guy. Hes got a 99 ws6 with lots of Blaine fab and strano stuff and a turbo system that isnt working to well at the moment. He rode with me and i rode with him, hopefully what i told him was good advice :-)

Yes, 4s.

I’m not sure how long it can record,, but these are 20 minute sessions and I might have had 4 sessions on there at a time?? I am having memory issues at the moment so I need to work out a solution to transfer this data while at the track.

The 2 laps I’ve shown you are the only vids that I’ve uploaded so far. I have full session vids that I haven’t figured out how to overlay with the GPS / Accelerometer data yet. For one lap at a time it is easy just select the lap in the ‘lap list’ and press ‘overlay’. It processes for a couple minutes and saves the 1 lap vid in the ‘photos’ app on the phone. From there I can post it on you tube or wherever else. But I can also watch the videos within the Harry’s lap timer app.

There are lots of other cool features like charts where you can compare your fastest lap versus other laps. Sometimes you might have a faster sector time in one lap that happens to not be your fastest lap. With that I could see that I started braking later which made me faster or I just had a faster corner speed etc. In the charts section you can overlay MPH, lateral acceleration, linear acceleration, altitude (height), and engine rpm for 2 laps at a time.

I’m still learning about it as I go so I’m sure there are many things that I’m not taking advantage of yet. The most annoying thing so far is my memory is full. On Harry’s website he recommends getting a higher memory phone and for some reason I missed that before I got my phone. I need to do some searching for a solution to this.

Yes, you do. It really is a life changer.

Brakes did pretty well I think. I was having a soft pedal that would start mid-way into the session but it would also get firm if I pumped the pedal going into the turn so I wonder if it is a pad knock back issues. It being there not at the beginning of a sessions makes me think it is heat related, but me being able to pump the pedal once and it get firm makes me think a wheel bearing might be loose. Also, turn 1 is after the long straight which is when the brakes get used the hardest. Turn 2 always had a firm pedal for some reason.

I used parts from here: http://www.rammount.com/ (recommended by Harry).

There is quite some flex in the mount so I’m sure that effects ‘jerk’ (rate of change of acceleration) but in a steady state condition the accelerometer will still be accurate. For example, in the esses where I’m in a hard right then immediately change to a hard left the accelerometer might be a little slow to change because the mount is moving, but once it has settled the reading will be accurate. I have a feeling that some flex is a necessary evil to damp out high frequency vibrations that will damage the phone.

I’ll post up a pic of my mount system.

They have some cool stuff!

I'm glad I'm not the only one. My friends look at me like I'm crazy when I say I've had two droids and all either one has done is make me angry. Mine is always crashing and doing stupid stuff. I thought I just had an old POS so I bought a new one (a current generation Motorola) and it's a bit faster but about as bad as the last one.

My GF has an Iphone 4S and likes it...but I don't like Apple anymore than I like Google or Microsoft...(guess I'm screwed).

Yeah, pretty much Or just get over it and get the iPhone. It's my first Apple product and I like it a lot.

If I could do it over again I wouldn't get the long arm, I'd get the short one instead.

Also, the battery drains fast so I got a 10' charge cable from Amazon... having said that the damn thing doesn't work so I have to trouble shoot that.

I'm getting the iphone 5 tomorrow! I can't wait. I will NOT miss my Droid X!

Look into getting a higher memory version if there is such a thing..

I'm planning on it. Going with the 64 GB version.

From this past Sunday Here is my fasted video lap of the day at Gingerman:
http://youtu.be/3FoC7Tck5EA

I ran all day with my fat(lol) brother as a passenger. I had a 145:99 recorded in data (no vid) and i had some clean laps at the end that I didn't get any data for due to some sort of technical difficulty (memory?). So far i haven't made this app bullet proof reliable but i have a feeling my issues might be something i can fix by clearing up more memory.

Im going to run the Motor State Challenge on friday http://www.motorstate.com/msChallenge.htm/ Ill be on race tires so i wont be officially competing but it will be fun to see how i stack up to the top mega dollar and high horespower pro touring cars. They ran the shorter course last year and i don't have times for that config.

Great vid Stan, looking good out there!!!

Good luck at the MSChallenge!

Costas
cars and such...

Glad to see you getting the car out. Unfortunately, our Optima 3rd gen isn't done enough to run in the MSC. Bruce is going to bring it up there but there's still a lot of loose ends to tie up.

What tires and HP are you running? I'll try to get some video up from when I raced there in June, there's some more time on the table. I was into the high 1:43s on dead Toyos (dumb tire choice) and my AI record is a 1.42.5 on the long course.

I could listen to the noises that thing makes all day long!

Here is my best lap from the Motor State Challenge and my best lape to date at Gman:
http://youtu.be/JoG0FDam8n8
141.7 per my timer (GPS) and 141.96 per the MSC timer (probably more accurate)


5th fastest lap of the day out of 98 and probably the fastest car under $100k. Because I'm cheap i refuse to spend $1200 on a set of street tires to be legal i ran my scuffed Grand Am Continentals (race tire). Most everyone else was running BFG Rivials (tread 200) but the top cars also had ~200 HP more than I so I call that a fair trade.

That 1:41 lap suprised the the heck out of me and really made me realize how much the little stuff in driving matters. I've watched that vid a dozen times now and I can see where there is more time on the table but I also realize that being able to put it all together in one lap is difficult.

I've also done very little tuning on this car. I cant even tell you what my front Koni's are set to. I've never tested tire pressures I just run 39-40 psi like Dean Martin told me to. Im also still right foot braking with a dog box, Id guss that there is a second on the table for LFB. But nipping away at these details and consistently going faster sure is a heck of a lot of fun My best time a year ago was 5 seconds slower

Nape, I talked to Bruce for a little while and drew the conclusion that he was the friend of yours that had the 5th gen and the 3rd gen that you told me about. Thats a great looking car and I envy the fender flares.

I've never dyno'd my car but Id guess around 400 rwhp. 3150 lbs with me in the car.

Power Tour Long Hauler - that is freaking awesome. I'm a long hauler myself, but not in a true race car. I had my '68 Camaro back then, was a pro touring car.
