EVision Installation, cont.

The EVision is now up and running, beeping and flashing as it keeps track of amps and voltages. Here’s the display on the dash:EVision in DashOut of the box, the display is configured to mount upright. The MR2 dash doesn’t have a large enough ledge for the base to fit so I turned the internals upside down inside the housing so that the base could be screwed to the underside of the hood. It looks good there, blocking out the non-functional tachometer, though the display does wash out in direct sunlight as the binnacle doesn’t shade the EVision display as well as the other instruments. Maybe in the future I’ll better integrate it into the main cluster, dropping some of the non-functional gages as well.The HMI (Human-Machine Interface) takes the place of the gear shifter in the center console:Console ControlsThe EVision HMI is similar to the iDrive system in BMWs in that the knob responds to rotation by cycling through menus designed in the software program and selects items by pushing down on the knob.  The white LED is surprisingly bright at night, if the black plastic switchboard was changed to a clear plastic it might be enough to illuminate the other switchgear.  The other controls are the drive selector switch in the middle, full/low power toggle on the left and regen on/off on the right.
