Using the Sport Chrono/Sport display function.
I've done some browsing, poured over the section in the PCM manual and still can't quite grasp how to properly use this Sport Chrono as a lap timer. I was wondering if anyone could list the process in simple enough terms for my feeble mind.
I'm particularly interested in how to record a trip/lap distance, save it, and then have the car properly time/record my laps. I'm hoping it's more than just a gimmick and I'll be able to obtain some relatively accurate times during an HPDE.
I greatly appreciate any assistance with it.

Yes, I've played with the start/stop/interval etc on the stalk but wasn't sure how to have it record a distance/lap and then time that lap repeatedly. (ie: lapping)
Surely you wouldn't have to activate the stalk every lap would you? I understood it was able to automatically record your laps each time you travel the recorded distance.

You have to manually bump the stalk each time you want to start a new lap. It doesn't start the new lap automatically.
If you have a recent iPhone, you could buy "Harry's Lap Timer" from the app store. It uses GPS to time and record your laps. It works quite well. If you don't have a convenient mount for your phone, buy some velcro and stick the phone to the dash or the inside of the windscreen when you get to the track.

I wouldn't have a problem hitting the stalk once to mark a lap, but my recollection is you have to move it twice, which makes it almost totally useless for timing consecutive laps. Any system that would not require you to mark a lap manually would have to be GPS enabled or utilize a track side beacon. However if you can master the too complicated lap marking dance, the circle graphics that show you current lap compared to your fastest and bar graph of the whole session are kind of cool.

I've got a Traqmate, myself, but that or a RaceKeeper is going to cost $1-$2K which is hard to justify for most casual DE participants.

Should be no need for GPS or beacons to record time/distance.

Perhaps I misunderstood the manual but it seemed like the system is or should be able to record a distance that you manually mark the first time around. So start the timer at the line, record the distance around the track (say a 1.6 mile lap), then stop again at the finish. Then the next time you start the timer it will know you're driving that 1.6 mile loop and automatically record each lap as you cross that distance.

I seem to remember you don't have to hit the stalk twice to begin a new lap. You select sports display mode on the trip computer and use the stalk to start timing. Then you push down on the stalk to select some kind of intermediate timing option and you push the stalk forward once to time each lap. At the end of your session you select the stop timing option.

You start the timer with the OBC stalk on the left. When you arrive to the destination you use the stalk to stop it. It does not give 1/100s precision but you may not need that. Last week on the track I saw a team manager timing a car with a regular stop watch... same difference.
On '09 and later cars you can also download a digital file (to a USB stick via the USB port) of the recorded timed event with speed, acceleration, and other param info.

Just some ideas.
