Changelog

All notable user-facing or behavior-altering changes will be documented in this file.

XXX 2021 Release

2021 Printing Ink Day

Breaking Changes

• Closed loop idle timing behavior changed to no longer fall off control as entering/leaving the idle region. It now sharply engages/disengages upon entering/leaving the idle area.
• Idle phase logic uses the same idle detection thresholds as the main idle controller instead of its own thresholds.

Added

• Main Relay bench test button

Fixed

2021 Orthodox Christmas Day

Breaking Changes

Added

• Second wideband O2 processing as channels "Lambda 2" and "Air/Fuel Ratio 2". Currently only supports CAN sensors, but analog will be supported too soon.
• Basic fueling-only flex fuel implementation. Automatic adjustment of stoichiometric ratio based on ethanol content, compatible with the common GM/Continental 50-150hz flex fuel sensor 🎉 🎉 🎉

Fixed

• Simplify idle control dialog in TunerStudio
• microRusEFI outputs are in trouble on configuration change
• CLT gauge no longer erroneously shows "deg F" by default.

December 2020 Bake Cookies Day

Breaking Changes

• GM x24 trigger now uses 0 offset (offset is now built in, previously needed 50 degrees offset)

Added

• DAIHATSU 3/4 cylinder trigger https://rusefi.com/images/triggers/trigger_6.png
• Ford ST170 VVT cam trigger https://rusefi.com/images/triggers/trigger_42.png
• Changed scheduling timer driver to improve scheduling accuracy #1983

Fixed

• microRusEFI GP3 & GP4 fixed

December 2020 National Mutt Day

Fixed

• minor bugfix - engine sniffer missing pin names #1995

November 2020 Release - "Black Friday"

Breaking Changes

• "AFR target" table is now "Lambda target" table. It should convert itself correctly, but a backup of that table is recommended when updating firmware/ini.
• "Base cranking fuel" is now in milligrams, using the full injector model at all times now. 60mg per liter per cylinder is a good starting point

Added

• High & low pressure fuel sensor channels
• Electronic throttle-style wastegate control found on some VW turbos (and VGTs)
• Improved TLE8888 driver on microRusEFI
• Improved setting ECU presets/defaults from TunerStudio

Fixed

• Improved TunerStudio protocol reliability - should see fewer CRC errors now #1943

October 2020 Release - "Sausage Pizza Day"

Added

• iat as FSIO variable to read intake air temperature
• [ALPHA] Software based knock detection on Proteus v0.4+. Possible on microRusEFI and Frankenso too with hardware modification.
• [ALPHA] Early framing work for automatic transmission control!

Fixed

• Fixed fuel pump logic
• Improve trigger input/decode and PWM performance
• Fixes to SD card logging
