I don’t know which sevcon, I’ll look. Do i need dealer software, a cable and online access for the firmware, or can anyone do it? and did I understand correctly that the 75-7 is the same engine as on the DSR and sr?
You need at least a sevcon Software and and an Ixxat and probably a passende or pin , then you can change whatever you want.
Maybe someone with a Zero and more knowledge can help you, I only know what is nececary to program a sevcon.
