New Features

• Initial implementation of knock control has been added. This is for use with external knock controllers that produce either a pulse based or analog output to indicate knock levels.
• Added ‘TunerStudio’ protocol on the secondary interface for use with devices such as the AirBear module. Note: Currently this protocol can only be used by either the primary or the secondary interface at any given time, 2 connections cannot be used simultaneously.
• Many improvements to CAN BUS functionality:
  • Add CAN support for AEM 30-0300 X-Series wideband controllers
  • Haltech Dash (Eg IC-7 / UC-10) protocol support added
  • Fixes to multiple fields on BMW dash outputs
  • Fix AFR and Flex fields showing wrong values on OBD2 protocol
• VSS limit added to launch control options
• Many improvements for Teensy 4.1 based systems (Eg Dropbear V2) including faster startup time and comms
• Indicator added to TunerStudio and log for Fuel Staging
• Added Honda J Series decoder (#1202)

🐛 Bug Fixes

• Major improvements to Serial comms robustness to avoid pauses or hangs when corrupt or invalid data is sent
• Fix an issue on Windows where connecting the ECU to USB would cause the ECU to wait indefinitely for serial data even when TunerStudio was not running (#1112)
• Verify there is sufficient buffer space before writing an SD card log entry. This prevents a potential wait that could occur if the buffer was full
• Display the correct existing O2 sensor calibration when opening the dialog in TunerStudio
• Fix Rover MEMS decoder not correctly determining sync for full sequential (#1240)
• The calibration settings for non-GM / Continental Flex sensors were being ignored (#1247)
• Fix stepper driver always being held enabled when open loop mode was used
• Fix the flex boost adjustment being added to boost target multiple times
  • All other fixes that have been included in the 202402 Fix Packs
