1.7.1
Firmware Version
It is recommended to ensure that the ECU is running the most up to date firmware. Firmware version
information can be obtained by connecting to the ECU with PCLink and selecting 'ECU Information' under the
Help menu.
The latest firmware can be downloaded from our website with PCLink.
It is recommended that firmware updates are performed by an experienced Link dealer as new features may
need to be properly configured.
The firmware can be updated by selecting 'Update Firmware' under the 'ECU Controls' menu in PCLink, follow
the on screen instructions to complete the firmware update process.
1.7.2
Base Configuration
All Plug-In ECUs are shipped with base configuration settings. Note that these are provided to reduce initial
setup and tuning times. They are NOT recommended tuning values. PCLink includes base configurations for
various models. Download the appropriate base configuration into your ECU with PCLink by connecting to the
ECU (described in the Connecting To PCLink section of this manual), then selecting 'Open' under the 'File'
menu. Select the appropriate .pclx or .pcl5 file and then select 'Open'. Downloading large configuration files
can take up to a few minutes. Be patient and acknowledge any messages PCLink shows.
1.7.2.1 WRXLink (11)
The WRX 11 covers many model variations, for this reason there are several sample maps available in PC
Link which will cover most of the common set up differences, load the map that matches your year range and
“starter type” closest. Due to the large range of regional and optional spec variations, the supplied sample
maps may still need some further manual setting changes to match the vehicle. The main variations to be
aware of follow:
·
CAN Mode – there are several CAN variations, If you have ABS or DCCD warning lamps remaining on
the dash then try the other modes for the same year range that are available in the list. Do not be
concerned about using a “key start” CAN mode in a “button start” car or AUDM CAN mode in a USDM
car. Note the ignition needs to be power cycled after changing CAN mode.
·
EJ20 Vs EJ25 – change the “engine capacity” setting to match your engine.
·
AVCS on intake only or Intake and exhaust. All our sample maps are set up for 4 AVCS cams. If your
engine doesn’t have exhaust AVCS then go to >VVT Control>Bank ½>Exhaust Bank1/2 and set the
Cam Sensor Input to OFF and PWM Output to None to prevent errors being generated.
·
USDM O2 sensor heater output. The WRX11USDM ecu uses a different output for the O2 sensor
heaters. Go to >Auxiliary Outputs>GP Output>GP Output 1 and change the output to Aux 16 and
change the Active state to High.
·
MAP Sensor – Most cars use the “Subaru (V9)” MAP sensor calibration, but we have found some
sample models use the “Subaru (V7-8) calibration.
1.7.3
MAP Sensor Calibration
At key on and engine not running the Manifold Absolute Pressure (MAP) Sensor should always match the
Barometric Absolute Pressure (BAP) Sensor. As well as providing altitude correction, the BAP sensor also
allows the MAP sensor to be calibrated prior to tuning.
Link ECUs use an on-board barometric sensor that is calibrated prior to dispatch. This ensures that all
PCLink tune files (.pclx Files for G4X or .pcl5 for G5) give a consistent state of tune throughout the ECU
range. This allows a tune file to be transferred between G4X or G5 based ECUs giving an equivalent state of
tune providing all factors affecting volumetric efficiency are equal.
Without the ability to calibrate all the available types of MAP Sensors to the BAP Sensor there would be
significant affects on the accuracy of the resulting tune, especially when tuning with Manifold Gauge Pressure
(MGP) as a load index.
To calibrate the MAP sensor:
1. Connect a laptop/notebook PC to the ECU and connect to the ECU using PCLink.
2. Under the Analog Inputs menu, select 'MAP' then set the Source setting to the correct Analog Input and
set the Calibration value to the correct option for your MAP sensor.
3. Either in the MAP window or under the 'ECU Controls' menu, select 'MAP sensor calibration'.
4. Follow the on screen instructions.
