RPM feed

Is it possible to record RPM on an older car with no management system. Ie nowhere to plug an obd adaptor! Cheers

    RaceChrono allows DIY sensors via RC3 format (currently supported only in Android), usually you'd use hall sensors and count the pulses, in Arduino or similar, and output $RC3 sentences over bluetooth with the RPM value.

    It's either a DIY project, or you can buy a ready made here, although you'd still need to install the sensors etc.

    There might be other commercial products coming soon that do this, but cannot say anything for sure until they do.
