CORTEX CONFIG UPDATE INSTRUCTIONS

When updating to version 5.1.5 there are two significant changes to boost control behaviour that need to be considered.

(1)  Valve Latency settings have been removed.  This will have no impact for most users as these settings were typically left at 0.  If you did utilize the Valve Latency settings your boost control behavior may change after updating to 5.1.5 software/firmware.

(2) The Total Duty Cycle Limit has been split into two settings.  There is now a Total (+) Duty Cycle Limit and Total (-) Duty Cycle Limit that allow separate limits to be set for positive and negative control.  After updating to the 5.1.5 software/firmware the Total (-) Duty Cycle Limit will be 0 for all gears in all boost control profiles.  The Total (+) Duty Cycle Limit will have the old Total Duty Cycle Limit setting.  Therefore the Total (-) Duty Cycle Limit will need to be initialized if you are using the closed loop control functionality.

Before updating from the Cortex Nexus software to the Cortex Config software you will want to save the Control Map programmed to your Cortex EBC to your computer and take screenshots or pictures of your Vehicle Configuration and Output Configuration settings.  All settings will be cleared from the Cortex EBC during the update process.  You will be able to open the Control Map you save to your computer and transfer it to the device after the update (if you are currently using software version 3.0.0 or higher) but you will have to recreate your Vehicle Configuration and/or Output Configuration files.

After saving the Control Map to your computer you will want to download and install the new software.  The software name has been changed to “Cortex Config”.  The Cortex Nexus software will be left on your computer and you can use it in the future to open old data logs and configuration files for reference if needed.  Otherwise you can uninstall it from your machine.  After the Cortex Config installation is complete you can power your Cortex EBC and connect it to your computer.  When you establish a USB connection with the device you will be prompted to perform a firmware update.

When the firmware update is complete you will want to recreate your Vehicle and Output Configuration files.  The RPM detection algorithm has been redesigned and you may need to reference the help documentation to determine the new settings required for your particular application.  After creating your new Vehicle Configuration file use the logger to verify RPM, speed, gear detection, etc are correct.

After creating new Vehicle/Output Configuration files you will want to open the Control Map you saved to your computer before performing the update.  The settings have been reorganized in the software but they are all still there with the exception of the End Duty Cycle Limit.  Take a look through the Control Map settings to make sure everything looks right and then transfer it to your Cortex EBC.  If you were using the closed loop feedback control you will need to set the Total Control Duty Cycle Limits to something other than 0 or the closed loop control will not be enabled.

Finally you will want to update the display parameter on the Cortex EBC device.  The available display parameters on the device have been changed so the active display parameter may be different after performing the update.  Don’t forget to change the active control profile from OFF and reenable the outputs if you are using them.
