eDash Notes
•The mini-USB port on the top of the eDash is used to connect the eDash to a computer in the
event that an eDash update becomes available. The supplied USB cable is not used in normal
operation of the eDash.
•Please do not attempt to operate the eDash while driving. For safety, have a passenger monitor
live data or adjust settings as needed if the vehicle is moving.
•The eDash is compatible with mounting brackets that fit a Garmin Nuvi 2455LT GPS unit. A
suction cup mount for the eDash is included in the kit.
•The eDash has a touch screen calibration procedure that can be accessed by pressing and
continuing to hold anywhere on the screen as the eDash is powered on. After about 4 seconds,
the calibration screen will appear and walk you through the short calibration process. The
purpose of this calibration is to sync up the touch sensitive screen with the graphics on the
display so that where you see a “button” on the screen is also where you need to touch to select

it. This calibration is performed at the factory. It is unlikely that it will ever need to be
repeated.
Wiring Connections
A long handheld cable is supplied to connect the eDash to the ECU’s harness.
XFI 2.0
When using an eDash with an XFI 2.0 ECU, there are two options for connecting the handheld cable.
The first is using the supplied adapter to connect the handheld cable to the CALPORT connector on
the ECU harness. The adapter has a loose pink wire that needs to be connected to a switched 12V
source to power the eDash.

The second option is to install the supplied pigtail to access the XFI’s 2nd Comm port. The handheld
cable will connect to the installed pigtail. Again, there is a loose pink wire that needs to be connected
to a switched 12V source to power the eDash.
When the 2nd Comm port is used for the eDash, the CALPPORT connector is left available for
connecting to a laptop. This way, both an eDash and a laptop can be connected simultaneously.
XFI firmware “XFI_Flash_B1.xfi” (March 2014) or later is required to enable the XFI’s 2
nd Comm
port.

Pigtail installation:
1. Remove the C (31 pin blue) and D (16 pin gray) connectors from the XFI.
2. There are white locks in the connectors that need to be slid out about 1/16” to allow new wires
to be inserted. It is easiest to slide the locks out by pushing down through the top of the
connectors. Pictured below is the bottom side of a connector with the lock slid out and ready to
accept new wires.
3. With the white locks slid out, insert the three wires with XFI terminals into the XFI connectors.
They should lock into place.
•Black – D5
•Green – C30
•Gray – C31
4. After the new wires are inserted, press the white locks on the connectors back into place so that
they are flush with the connector bodies.

text will highlight green to indicate the current screen.
Across the top of every dash are 4 LEDs that indicate the following:

Logging
The eDash is capable of logging. It will log the minimum and maximum values of all of the sensors
displayed on the Master Dash. To operate this feature, press the Log button at the time you wish to
start the logging function. The Master button will now display the text Logging, indicating that it is
recording all minimum and maximum values that are being shown on the dash. There is no time limit
on logging, as it is only keeping track of minimums and maximums. To stop the logging function,
press the Stop button. The Stop button will now indicate if the minimum or maximum values are being
displayed on the screen. To see the next values press the Min or Max button. To clear the log and
prepare for a new logging session, press the Clear button. The Clear button returns the Master button
and you can now start a new log by pressing the Log button.
DATA LABEL
DESCRIPTION
AFR
Air/Fuel Ratio. The reading from the wideband oxygen sensor.
Air Temp
This is the temperature of the air entering the throttle body.
Battery
Battery voltage.
Boost PSI
Displays the Boost reading in pounds for square inch.
Coolant Temp
This is the temperature of the engine.
ESC Rtd
ESC Retard displays the amount of timing in degrees that the XFI is pulling
from the commanded timing value due to knock, if you are using the knock
sensor input.
Fuel PSI
Displays Fuel pressure in PSI, if a fuel pressure sensor is being used on the
pre-setup fuel pressure channel of the XFI.
IAC
Idle Air Control. This is the position of the idle motor. At idle, it will move around
to maintain the target idle speed. Displayed in “counts”. Higher counts mean
the idle motor is open more and allowing more air to bypass the throttle blades.
Its range is from 5 to 180.
Inj DC %
Injector duty cycle. This is a comparison of how long the injectors are open compared
to how much total time is available for them to be open. At higher RPM, there is less
time between injector openings. If this reaches 100%, it means the injectors
physically cannot flow any more fuel. They are already being held wide open.
Lb/Hr
Current total fuel flow rate into the engine. Given in pounds per hour. This can
be used to get a rough approximation of current engine power.
Horsepower = Fuel Flow (lbs/hr) x 2
Load
Calculated Load. A comparison of the current manifold pressure vs. the ambient
atmospheric pressure. Unlike the reading from the MAP sensor –which is affected
by altitude –Load should always be consistent. That is, wide open throttle should
always be around 100% regardless of altitude and ambient atmospheric pressure.
MAP
Manifold Absolute Pressure. This is a measure of the load on the engine. It is
displayed in kPa (kilopascals). With the engine off, this will read around 100
kPa. It will drop down when the engine is started.
MPG
Miles per gallon will be displayed if a speed sensor is being used.
MPH
Miles per hour reading from the XFI, if a speed sensor is being used.
O2 Cor %
Current closed-loop correction based on the reading from the wideband oxygen (O2)
sensor. This is the percent of fuel being added (displays as a positive number) or
removed (displays as a negative number) to achieve the target air/fuel ratio.
Oil PSI
Displays Oil pressure in PSI, if an oil pressure sensor is being used on the pre-
setup oil pressure channel of the XFI
RPM
Engine speed

Target AFR
Target Air/Fuel Ratio. The ratio the ECU is working to maintain.
Total Timing
The final timing value the engine sees. A timing light should agree with this value.
TPS %
Throttle Position Sensor. This tells you how far the throttle blade(s) are open.
Diagnostics
Codes
When an error code is set, the “Error” LED displayed on the eDash’s Live Dashes will turn on. If that
happens, use this screen to find out which code has been set. Codes can also be cleared here.
Master Dash
Brings up the Master Dash for a quick overview of all available sensor readings. See the Live Data
section for more detail.
