Manual for RaceChrono version 1.10
About
RaceChrono is a data logging software for all kinds of sports. It runs on Nokia S60 smart phones and uses position data from your GPS receiver to determine lap times and performance.
Getting started
To use RaceChrono lap timer you need a Nokia S60 2nd edition or S60 3rd mobile phone. Also either Bluetooth or Internal GPS is needed. RaceChrono team recommends using a good Bluetooth GPS for best accuracy. Good receivers are for example Qstarz 818 5Hz edition, or any Sirf Star III based receiver (which are 1 Hz).
Read moreUsing the internal GPS
RaceChrono supports the internal GPS on some phone models, but unfortunately the accuracy of RaceChrono suffers quite a bit when used with the current internal receivers.
The lap timing accuracy with an internal GPS can sometimes be relatively good, but a good external Bluetooth GPS is recommended for frequent track day use. One of the best receivers currently is the QSTARZ BT-Q818 eXtreme!
RaceChrono team does not recommend using the internal GPS for Performance testing!

Read moreUsing OBD-II reader
RaceChrono has experimental OBD-II feature. An OBD-II reader can be used to monitor and save various OBD-II channels provided by the ECU of most new cars and some other vehicles as well.
OBD-II channels that can be monitored include such as RPM, Speed and Throttle position. The OBD-II speed is particularly useful for performance testing, since it is more precise than the GPS speed which can be affected by weather and obstructions.
Read moreSettings
The settings are divided in four separate groups: General settings, GPS receiver settings, OBD-II reader settings and High/low speeds settings.
