    OK, GPS are here, getting packed and ready to shipped.

    Here are some instructions to get you up and running quickly.

    DO THIS FIRST BEFORE A TRACK DAY

    1. Charge the GPS first. You can use any old USB charger to do this from a powerpoint. Note: You will get a solid red charging light when charging and the light will go out when it is fully charged. When the GPS battery is running low you will see a flashing red light, this is the time to charge it again.

    2. Once charged go outside turn the unit on. Touch and hold power switch. Then with a pin hit the reset button (this is next the USB connector). This will force the GPS to do an cold boot and almanac update. This will take up to 15 min to complete. You only need to do this once.

    SETTING UP RACECHRONO

    3. Turn GPS on and pair with phone. For pairing password use '0000'. Important make sure you allow 'touchGPS' to automatically make connections to your phone.

    4. Run Racechrono.
    Goto Settings
    --> GPS Reciever: Select Bluetooth GPS
    ----->GPS Type: Bluetooth Serial GPS
    ----->GPS Device: touchGPS
    ----->GPS Baudrate: 38400 Baud ** Important for 5Hz logging

    5. Goto Track profiles and download all the tracks you will be attending. This is easier than doing it youself.

    AT THE TRACK

    6. Turn on GPS, Securely position on dash make sure the top is unobstructed. I recommend to thick peices for velcro from a hobby shop (ask your wives/girlfriends)

    7. Start up Racechrono. Select:

    ----New Session
    ----Session Title: XXXXXXX
    ----Session Type: Lap Timing
    ----Track: Your Track ie Wakefield
    ----Driver: Your Name

    Hit Start.

    Then Switch to Live Timer.

    You should now see a screen that shows, best lap, previous lap and current. Once you pass the start finish line it should start timing.

    That's it.

    When you're finished for the day (or even during) you can analyse laps, with graphs etc. Look at best/worse laps, delete rubbish laps like out and in laps etc.

    Things to look out for.

    Before you go out on the track check that the GPS is on (Flashing BT light, blue) and Racechrono is actually logging ie not in paused state! The GPS will auto power down when idle so it's important to check everything before you go out. When you come in PAUSE your session, if you don't the phone will continue logging to memory and create a huge file. Next time you go out restart Racechrono and just RESUME your session. It will take no more than 30 secs to restart. I suggest you do this *BEFORE* putting on you helmet, gloves etc.

      excellent, thanks MZ :D

      I've been playing with the logging etc @ 1 Hz, so am looking forward to having 5Hz at my disposal.

      I'll upload some stuff I'm working on in terms of outputs/graphing to give ppl an idea what's possible, sometime in the next coupla days!

        Are you using any PC based software to analyse data? Or just the phone?

          Am planning on doing stuff in excel.

          have been using the phone, but I find while it's fun sitting on the couch watching TV it doesn't tell me what I really want to know easily- like braking distances, speed at apex etc between 'laps'.....

          I have tonight pretty free, so I'll spend some time with it. I really should have dumped the files and emailled them to work.. :D

            Can I get one of these to work with my laptop or does it have to be a phone?

              RaceChrono is only for Symbian and Windows Mobile devices. I would image there would be other Windows based logging software but personally I wouldn't want a laptop strapped into the car at track speeds.

              Look up http://www.chronogps.com/ it has Windows 95-Vista support.

                Thanks, the only reason that I ask is that I have a 3 axis accerometer allready fitted up for datalogging on my mini laptop. Would have been cool if I could have linked it with this.

                Cheers

                  ChronoGPS will work with these GPS devices to do exactly what you want.

                    OK I've been playing around with the performance tools software from Race Logic

                    http://www.performancebox.co.uk/dlsoftware.html

                    the same dudes that make Vbox and stuff...

                    it's a free download.

                    Essentially you export from RaceChrono on your phone, as a .vbo file, and then load it in the software. you can then graph things like speed vs time and speed vs distance, Lateral G and stuff like that.. fun fun fun..

                    I've learnt two things.

                    1) the GPS on my Nokia N96 ( 1 Hz!) is wildy inaccurate when it comes to determination of height above sea level- two runs on the same 10 km of 'track' show some big inconsistencies.

                    2)If you are comparing 'laps' with point to point data - like a special stage- it's hard to get them to line up properly as the start/finish traps aren't exported from RaceChrono... but it's not hard to get them pretty close!

                    I'm now going to try the Danas L2M software and see what that does and if I think it's betterer :D

                        Some of you will get a fully charged ones. So don't worry if the light doesn't light up. I pulled some randoms out of the packaging to do some QC on the shipment.
