No Australia option

Please add an option for Australia!!

Works really good BUT…

Like the title says it works great and is actually very fast even compared to the VCM3, my only complaint would be not allowing programming and would be nice if the PIDS had a better description when selecting them.

Pids

Manque beaucoup de pids pour la valeur du vcm Lite

Never works correctly

I have the worst time ever getting into this application. Only works a fraction of the time and is not efficient even when it does work. Connection issues and slow loading even on wifi. Probably one of the most frustrating apps I have ever used. And if I did not have to use it, I absolutely would not.
