GPS and the ipod

Thanks, guys.
This has been interesting. I guess, for the time being, I'm going to stick with TracMate and beat myself up after the fact.

There is a iPhone with no SIM here in the office. I think it was still able to use the GPS. I got a location on maps without being connected to wifi and in airplane mode. This was likely my longest use of an iPhone though so take my testing with a grain of salt.

External GPS for Iphone/Ipod Touch that is supposedly 5hz

Gwen, AFAIK, you don't have to depend on MaxQ's proprietary hardware, you just need a GPS signal

nice find, Ryan!

What iPod/Phone apps do a good job with track-related GPS datalogging?

you can always go the cheap route like Ryan and myself have.

5hz sampling seems to work ok.

Maybe for a stock mini. Not for a CM car in an autox. :wink:

Gwen,

Unless you have a really fast codriver to compare with, at this point you have enough experience and skill to be able to "tell yourself" where you were probably either giving up time (not at the limit) or overdriving. For the next run focus on faster corners that will allow more corner speed and slower corners where you can change line to get on the power quicker by getting the "turning part" of the corner done sooner/quicker so that you can unwind the steering and mat the throttle. I find that it takes "concentration" to remember to make the tighter corners more like a "diamond" than a smooth arc. You might be amazed at how violent you can be with the steering wheel at relatively low speed if you can immediately unwind to either stop understeer or catch oversteer.

If either you or Bernie knows what oval track drivers mean by "diamonding" a corner (early apex in, HARD tight mid corner steering, late apex out) that is what I mean. I learned it by watching REALLY fast Corvette drivers in a realitively small lot. It applies to slower cars also!

Interesting. I downloaded this app not 3 weeks ago. I just went to itunes store so that I could tell you exactly how I found it and as far as I can see, it's no longer available. So, I went to their website where I was told to go to the itunes store. So, doing the math and adding that codes have been difficult to get, my guess is that they are pretty much out of business.

That's what I was afraid of

With Apple's draconian lockdown on stuff, I bet you can't even email it to me.

Yep, you're right. I've tried to email it. Went into my files, etc, to retrieve it and when I checked it, before PMing you for your email, found that it just won't allow me to.

Originally, I found it on itunes in a sports category. Just weird that I can't find it now.

Internal GPS on the iPhone is garbage. At least its proven to be useless for me. My wife has a 3GS, and it loses GPS lock about 5 seconds into a run and never gives any useful information for the rest of the run.
