There are two ways to reset the trip part, which makes the car “forget” driving and battery behavior.

Reset “light” is through R-Link. This will reset the range indicator (GOM) to a value proportionally  related to the capacity of the battery. In effect it forgets how (un)economical you have driven. It was used in the old days to check how healthy the battery was.

There is also a harder reset, called the “two pedal reset”. Keep the driver door open, start the car, keep the gear in N, press and hold both pedals and press up key on the windshield wiper control until the averages message appears in the display. Now hold that button. First it displays the current values, then it starts flashing, then the average values display —. Now let go. This reset seems to also make the battery computer (LBC) loose quite a bit of acquired parameters and the GOM shoots up to a crazy value.

The car will rather quickly re-learn the state of affairs. Just don’t rely on the range indicator on your first trip after a reset.

Thanks to the kind people running the OVMS project, we have access to quite a bit of documentation on the Twizy. Unfortunately, the current developers are unable to implement this knowledge into CanZE, mainly because lack of Twizy to play with :-). If developing CanZE taught us one thing, it is that it is virtually impossible to add functions without the car available; remote testing simply doesn’t cut it.

So, if any volunteer is available, we would be happy to take him or her into the team. There is no hard prerequisite (hint: when I started I had not written a single Android program), but it would be fair to say the following would help, in diminishing order of importance:

  • Owns a Twizy, ELM dongle and an Android device, and is willing to play and experiment with it;
  • Can bear to stumble along and spend too much free time;
  • Has done some development in Java or C++;
  • Has done some Android development.

We would love to hear from you!
