December 2023 Release: Happy Festivus!

Welcome to the FOME 2312 release!

Breaking Changes

• Simplified VVT single tooth cam modes. "Single tooth second half" and "single tooth first half" have been replaced by simply "single tooth". This may require re-setting your trigger and VVT timing offsets if you used "single tooth first half" prior to this change. #178

Added

• Log per-cylinder true ignition timing (includes trim, knock retard, etc) #76
• Add mode for CLT/IAT sensors that are installed "high side" instead of typical "low side" #116
• Automatic supply voltage compensation for VVT solenoids, giving more stable control as battery voltage changes #209
• Configurable ignition timing limits, adding safety particularly for engines running wasted spark with a large cam #211
• Improved injection, ignition bench test UI and functionality: More gauges, fuel pump on/off buttons for injector testing, and configurable duration/count #219
• Preset for Mazdaspeed Miata (NB) IAT sensor
• Option to compensate Alpha-N fueling with intake air temperature
• Gasoline-scale AFR gauge: instead of showing true AFR, show "gasoline scale" where 14.7 means stoichiometric
• Decode fuel temperature from flex fuel sensors #254
• Allow brief operation over 100% injector duty cycle and add configurable duty cycle limits #215
• Buttons to bump VVT targets for testing/PID tuning
• Improved serial port selection for FOME console and firmware update
• Better default configuration values for some advanced features
• Support BMW E8x/E9x CAN speed sensor input (works for standalone MK60e5 too)

Fixed

• Improved bench test resolution (more usable for testing injectors, dwell, etc)
• Maximum knock retard table displays correct Y axis values in TunerStudio
• Make errors about fuel pressure sensors less aggressive #111 #117
• Always operate in "two wire" mode for batch fuel, fixing batch firing order #23
• Fix "Toyota 3 Tooth Cam" VVT mode (1JZ, 2JZ, 1G, etc) actually works now #237
• Fix autotune while TS project is in AFR mode - corrections now made properly for target AFR table values
• Changing idle stepper settings causes kernel panic #265
• Data log channel "Fuel: Injection timing SOI" indicates correct values
