Miles per kWh ?5.0 is pretty good. 3.3 is winter.Filter the instantaneous so out doesn't jump around too much and distract.Alternate is/with trip average.Sent from my T-Mobile 4G LTE device

Yea! Humming along just fine.
Question to the larger audience: As a default, what metric should
the ECU Simulator map to the Fuel Flow display element?
Most HUDs have a default display for fuel consumption, often in
Liters/hr (or configurable to that). The scale and # of digits is
limited - mine has a range of 0 to 19.9. I was originally thinking
something power-related would be appropriate, but none fit in the
display's range, and doing hokey things like scaling by 1/10 fail a
cursory usability test. I'm thinking a useful display, both for use
and as a verification of function, would be to display the metric
v.b.12v voltage. How does that sound?
Note that the individual elements can be re-mapped by command
(config set obd2ecu.map ), and these
values are stored in flash and automatically loaded when the obdii
ecu is started or reloaded. I'm just wondering what the default
should be. The other pre-loaded default PIDs are RPM, Speed, and
Coolant Temperature (which is mapped to Motor temp). One can change
any of these, and/or add more as desired.

it’ll jiggle, but not much else.
Would be nice to have it drive around the streets.
But following roads may be a little bit tricky.

Nice, useful tool. It also works to
"drive" the ECU simulator for displaying to an
external HUD / dongle.
But, the demo was somewhat underwhelming,
as the virtual car was just sitting there. Where is
the "Gitty Up" button?

To: OVMS Developers;
I’ve been working on a DEMO vehicle in
the firmware. This is enabled by:
vehicle module DEMO
The idea is that this vehicle exercises
all the metrics in a logical way. It can simulate
driving, charging, and sitting idle. Along with the
‘metric set’ command, it can be used to demonstrate
all the different modes. It works something like the
ovms_democar at the server-side, but runs on a
vehicle module itself.
It is intended to be used by firmware
developers for testing their functions. Things like
ovms_server_v2 and ovms_server_v3. Also, stress
testing on the bench (without requiring a vehicle).
Functionality is basic at the moment,
but it is working. I should be able to finish the
last parts of ovms_server_v2 now.
