Do you have to have your iPhone connected to power?

You get warned if you don't, but is the drain high enough that you might run out of battery power in a 20-30 minute session?

I usually charge my iPhone between sessions and that has always been enough for other apps.

Re: Ideal Lap

Clearly this is more difficult than I anticipated. I looked at it from an overly simplistic standpoint. Suppose you had two laps. In the first you apex a corner at 40mph and reach 120 on the subsequent straight. In the second you apex at 45 but only reach 115. The ideal is 45 and 120, except it real...

Ideal Lap

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 analyzed th...

Re: Can HLT be run out of sight?

You can use LapTimer in flat position but will not get G-forces recorded. Everything else works. - Harry I wish I'd read this the other day. I went thru agony getting a RAM mount installed properly only to find the organization I was running with doesn't allow suction cup mounts, even if tethered. ...

Is there a way to email a lap?

I checked the docs and couldn't find it. If it is documented, please tell me where. I have a space problem, 3.4Gb on my iPhone and 5Gb in iCloud. With another iPhone app I have used you can select a track and email the video and all the data to your computer, allowing you to free up space for more v...

Re: Calibration question

The Cayman will not be too different to a 911... Attach the suction cup in the top directly below the mirror. Harry I tried that but felt like it obscured my view so last night I tried positioning it behind the mirror to the right of the mirror mount. After playing with it a bit I found a location ...

Re: Calibration question

That's the one I have with the four prong spring-loaded phone mount. Unfortunately, the only way I could tether it satisfactorily was to mount it low on the windshield. You can see a tiny edge of the mount from the camera but mostly it is pretty clear. I checked trying to tether the mount to the mir...

Re: Calibration question

Have you checked the doc linked? Actually I strongly recommend to use a mount instead of placing the device in a position not in view and generating other issues. Quality mounts do not fall off for street going cars. Harry I agree they shouldn't but I have had problems with several suction cup moun...

Re: Calibration question

True, flat doesn't work - except you calculate acceleration from GPS after the fact instead of measuring it. - Harry I, too, place my phone flat. I don't do videos on top of which I don't trust window mounts. I put it under a net behind my seat with a view of the sky (Porsche Cayman). So, what will...
