I posted a compilation of the '08 300C EVIC "easter egg" screens back in November and have been updating them as new items are discovered. I've decided to clean it up and update it, hopefully this will be useful to all.
w and I'll add your name in.
Please let me know if there are any errors or omissions.
Kudos to: Romli (I think he started it all), dnar...
To all that have posted information that help make this compilation possible, big thanks! Let me know and I'll add your name to the kudos.
How to Access and Exit
To access the "easter egg" EVIC screens, do the following:
Press and hold the Music Note (♪) key and the Compass key for a few seconds.
Up and Down arrow moves through the screens.
To Exit, just hit the compass key or the page key.
Screen 1
Version Date - Date of version
Version Number - Version number
Part Number - Part number
Screen 2
[Speed] [RPM]
[Engine Temperature]
[Battery Voltage]
Screen 3
TempAVG - Numerical value in degrees F or degrees C
Averaged temperature from raw sensor readings
TempRAW - Numerical value in degrees F or degrees C
Raw temperature sensor value (instantaneous)
Last line, no definitive definition but seems to be time counters which might be used in the averaging program.
First number counts up in seconds when the car is in motion. The second number counts up much faster when the car is in motion.
Available Actions:
▸ Resets Average
Screen 4
Compass Raw - Numerical value in degrees
Raw compass reading in degrees from magnetic north
Oil Press - Numerical value
Oil pressure value in PSI
Pdl Pos - Numerical percentage value.
Position of the accelerator in %, peddle to the metal = 100%
Screen 5
MinL - Number
A sensor value associated with the left fuel tank, uncertain what this measures.
MinR - Number
A sensor value associated with the right fuel tank, uncertain what this measures.
Lt - Number
Current left fuel tank volume in PINTS (i.e. value divided by 8 = gallons)
Rt - Number
Current right fuel tank volume in PINTS (i.e. value divided by 8 = gallons)
19g - Constant
Full tank capacity, 19 gallons.
Avg - Number
Average value of total fuel volume in PINTS (i.e. value divided by 8 = gallons)
Screen 6
AutoHLSens - Number
Current value of the light sensor for the automatic headlight system (instantaneous).
Higher Number = Darker
TC - 2 Numbers
First number is a dampening (averaging) value, the higher the number, the more dampening occurs.
i.e. Higher the dampening value, the longer it will take for the lights to come on when it gets dark and longer it will take for the lights to go off when it gets bright. So if you go through a lot of short tunnels and don't want the lights to keep going on and off, increase this value.
Second number is the damped sensor value.
Thld - A number and up to 2 alphabets
Current threshold value. If damped sensor value exceeds this value, lights will come on. If damped sensor value goes below this value, lights will go off.
A = Automatic Headlights On
H = SmartBeam Automatic High Beam System On
HBduty - Numerical Percentage
Shows the current intensity level of the SmartBeam system, 0% = off, 100% = full high beams.
Available Actions:
♪ Increases dampening value (max out then loop back to lowest value)
▸ Increases threshold value (max out then loop back to lowest value)
Screen 7
LastChm - Last Chime (Phrase value)
What caused the last alert chime to go off. i.e. "Brk Fluid" - brake fluid light, "Airbag" airbag light and "ACC" if the adaptive cruise gave you an ATTENTION due to rapid closure and auto-cancel.
Great for alerts that don't leave a "residue" so you can find out what the hell the last ding was trying to tell you.
VTA - Vehicle Theft Alarm (Phrase value)
If alarm was triggered, value indicates the sensor that caused the alarm to go off, i.e. fault code.
Wake - (Phrase value)
Indicates how the car was turned ON, i.e. "CAN Bus" = Remote starter.
VMM 646 - Constant?
Unknown
Screen 8
Current battery voltage bar chart and exact voltage reading.
Screen 9
Fuel economy bar, PERFORMANCE indicates V8 mode, ECONOMY indicates MDS active.
Available Actions:
▸ Displays two additional numbers at the bottom, Average MPG and Instantaneous MPG
♪ Selects an MDS indicator icon which will appear in the regular EVIC Compass screen.
Cycles through the following icons:- FS
- FS in a circle
- MDS
- Leaf graphic
- ECO
- V4
- Blank
Screen 10
Digital Speedometer.
Doesn't seem to work in the 2008s.
Screen 11
0-60mph Acceleration Timer. Will reset automatically if you take more than 10 seconds.
READY will flash when it is ready to go.
Available Actions:
▸ Resets last value or shows current best time. 
Adaptive Cruise Control
If you have ACC, when you are in the "easter egg" screens and the ACC status appears, it will have 2 additional numbers showing you the current distance to the object in front of you and the current speed that you are travelling.
