• Fixed bug causing flex fuel content to be displayed incorrectly on device

• Updated RPM detection algorithm to help reduce noise/spikes when using a coil pack trigger as an engine speed signal source.
• Improved display algorithms to reduce flickering captured by video cameras.

CONTROL MAP

• Control Map parameters have been reorganized into Fail-Safe, Open Loop, and Closed Loop categories.
• Flex fuel content and fuel temperature fail-safes have been added.
• Water/methanol flow fail-safes have been added.
• Activation time limit has been added to WBO2 fail-safe logic.
• End Duty Cycle parameter has been removed and replaced by a Total Control Duty Cycle Limit parameter in the Closed Loop settings.
• Gear  Change parameters have been added to help reduce boost spikes that occur on applications where the throttle plate remains open during gear changes.
• Spool Hysteresis parameter has been added to allow spool logic to be reactivated before boost returns to 0.0 PSI.
• Use Transbrake parameter has been added to launch options.
• Gear detection expanded to support up to 8 gears.

VEHICLE CONFIGURATION

• RPM detection has been redesigned and now uses two parameters for all signal types.  The new algorithm can handle cam or crank position sensors with just about any tooth/trigger pattern.
• Analog Input is now a General-Purpose Input that can be used with some frequency based sensors.  Available Options now include:
  • Throttle Position Sensor
  • WBO2 Controller Linear Output
  • GM Flex Fuel Sensor
  • SIRHC Labs Water/Methanol Flow Sensor
  • Transbrake Switch
• Throttle logic has been updated to support inverted throttle signals where voltage decreases as throttle angle increases.
• Gear detection parameters have been updated to support 8 gears.

OUTPUT CONFIGURATION

• Output control resolution has been expanded from boost based 24 point 2D tables to boost + RPM based 384 point 3D tables.
• Time based progressive ramp can now be reset on gear changes if all other activation criteria is still met.
• Gear based activation parameters have been updated to support 8 gears.

LOGGER

• Chart View has been added to create charts from data logs.
• Road Dyno has be redesigned to use vehicle speed calculated by the Cortex EBC.

MISC

• Parameters that can be displayed by the Cortex EBC device have been changed.
• Peak boost can now be viewed on the Cortex EBC display.
• Bug causing RPM and VSS signals to occasionally dip when a gear change is detected has been fixed.
• Bug causing calculated MPH to overflow and drop back to 0 above 160 MPH has been fixed.
