RaceChrono v1.25 Beta1 S60v3 S60v5 SymbianOS9.x Signed

RaceChrono is a GpS based based lap timing software for Nokia Series 60 smart phones. It can be used to measure lap times on almost any vehicle and track. It can be used to measure laptimes for example for motorbikes, bicycles, cars, water jets and quadbikes.

The main feature is of course the Live Timer, which shows your lap- and sector-times in real-time. Also included are a scalable graphical display of traveled path, satellite reception display, speedometer and a compass. When you're back at the pits, you can also browse through your lap and sector times, or view your trap speeds. Or maybe analyze your laps by graphs of time, speed and altitude compared to any another lap.

All lap timing sessions are logged, and the results can be viewed afterwards. The raw NMEA-output from the GPS is also saved, so you can use that in other compatible software if you wish.

And yes, there's always the question of accuracy when it comes to timing anything. After extensive testing, we feel really confident on RaceChrono's accuracy. Our tests together with commercial lap timers have showed an accuracy of between +- 0.03-0.10 seconds with a cheap 5 Hz receiver. Switching to an ordinary 1 Hz SirfStar3 receiver RaceChrono was still very accurate - on the level of +- 0.10-0.15 seconds. Keep in mind however that accuracy is fully dependent on the quality of your GPS receiver

and signal reception.

Note that if the signal from the satellites is too weak, your lap times can be inaccurate and in worst case you can even miss some laps. So take care to position your receiver properly on your dash close to the windshield, or maybe even outside the car! Use the satellite reception display to help you find the best location in your car.

You can download tracks from the RaceChrono software itself; by selecting Track profiles > Options > Download new. Just copy the downloaded file to /RaceChrono/Tracks/ on your memory card
.

change log:

· Standing start feature for lap timing. New standing start trap type is added for better Hillclimb and Rally starts.
· Slightly modified performance testing standing start algorithm
· Previous sessions list will now show lap count and best lap time
· NMEA and DL-1 importing (+ removed the incomplete G2x import)
· GPS input file is now selectable when GPS type is set to “Input file”
· Improved file selection dialog (for importing)
· Sessions recorded with OBD-II reader and be now resumed without OBD-II and vise versa. Remember to turn off “Use OBD speed” in performance testing sessions if you do that.
· Support for S60 2nd edition phones
· Non-touchscreen phones: Added menu options to Zoom map in/out to the Graph view. This is to help users find the shortcut keys.
· Small user interface improvements
· Fixed: Wrong units in .CSV export OBD-II channels
· Fixed: Bearing decimals were truncated in Performance Box session import. This made Lateral-G calculation very bad.
· Fixed: Lateral G-force calculation from GPS data were wrong. The calculated values were half of the correct value. The new algorithm is now checked against Race Technology and Racelogic software.
· Fixed: Time/date was displayed for the composed Optimal Lap
· Fixed: GPS and OBD time display stopped when day changed.

· Fixed: Sometimes invalid date was imported from Performance Box and VBox files
· Fixed: Importing file selection did not work for files with lowercase extension
· Fixed Symbian: Left side softkeys bugs (N93, N93i)
· Fixed Symbian: Could not enter decimal separator, if it is other than dot in phone’s regional settings (Atleast Nokia E61 and 5800).
· Fixed Symbian: Live Timer crash in Data Logging sessions on E71’s v21.x firmware
· Fixed Symbian: Edit box did not scroll properly.
