Browsing around the Lotus boards, I found some people modding their dials and lcd screens: Did anyone here perform any of those modifications?
The OVMS system had an option to change the digital Amps display to show speed. Done in software - no hardware change.
1. Flash roadster-specific firmware. 2. Enable can write (feature 15=1) 3. Enable OVMS digital speedo feature It's not perfect, but pretty good.
