Getting Started With Your Element Engine Management
you for purchasing one of the most powerful engine managements systems,
the Element Hydra EMS. Every effort is made to offer tuned maps for your
specific set of modification but some minor adjustments may be necessary
to perfect the mapping. Every car is unique and most likely there are
areas that can be fined tuned and improved specifically for your car.
better to be safe than sorry so if you do not understand what you’re
changing or the effects your changes make, please contact Element Tuning
for technical support.
Wide Band 02 Sensor
Most Element Hydras are
now shipped with the WB Calibrated however it may be required to
calibrate your WB 02 sensor for the best possible accuracy while tuning
your vehicle. After installing your Element Hydra EMS, connect the serial port to your laptop. Before you can make any
changes to the programming you must first select “Upload from ecu” so you can view the mapping in your unit.
Under the comments area you will see if the WB has been calibrated as you
will see a message such as "WB calibrated 125/182." If this is the
case you do not need to recalibrate your WB.
Select “Upload” and once the upload process is complete the menu will
disappear and you can select “Maps” to view the file.
In the “Maps” area you will see data
values on the left. "AFR" is what you want to pay attention to.
In the menu bar choose “Select," click “Settings,” and “Sensor” will be
the first that appears.
Under “Wego Zero Grad Cal” adjust this
value until your AFR reports 14.7 without the WB plugged into the harness.
Plug the WB sensor into the harness but do not install the 02 sensor into
your exhaust system. Turn the
ignition key to the start position but do not start the vehicle
which will start heating the WB. Let it warm up for a couple of minutes. Once the sensor is warm note what the "AFR" reads.
If it's richer than 20.8 then you will need to increase the value under "Wego
Grad Cal" and if it's leaner than 20.8 then you will need to decrease this
value. You must type in the value, click "enter" and then click "OK"
for the "AFR" reading to change. Repeat these steps until you reach
the AFR value of 20.8.
Make sure to save these changes and download them to your Hydra to make
them permanent. You can now install the WB 02 sensor into the
exhaust system. The ideal location for you WB is about 6-8" after
the turbocharger in the exhaust and clocked in the 10-2 o'clock location.
Sometimes the rear OEM location is acceptable and sometime it's too far to
keep the sensor hot enough. You will need to test this location if
you do not have the means to relocate the sensor closer to the
Note: The Hydra EMS does not utilize the OEM front 02 sensor.
It is recommended that this sensor is removed and only installed when
using the OEM ECU.
Save and Download
To make your changes
permanent you must save these changes to your laptop and download them to
your Element Hydra. Select “Maps” on the menu bar and then select
“Save.” Logically name the file and save it to your hard drive.
Close the red tuning
screen to view the “Download” screen. Select “Download” and then
“Download” again using the appropriate com port. Once the download is
complete you can select exit.
The last and most
critical step is that you reset your Element Hydra ECM by turning the
ignition to the full off position to reset the ecu. This usually takes
10-15 seconds. Your changes are now permanent.
