I did a 1h+ drive this weekend. I did not see any issue after 45 minutes of driving. It still works after 1+ hour. (PID ego with wideband lambda is...

What board are you selecting in TS to make this happen?

Hmm i cannot find any changes that created a pin conflict between 202108 and 202207. And i have no STM32F401 board with a windbond eeprom chip to test. I do...

Look at line 30 in board_stm32_official.ino and make sure the correct MISO, MOSI en SCK pins are selected. In 202107 those are: `SPIClass SPI_for_flash(PB5, PB4, PB3); //SPI1_MOSI, SPI1_MISO, SPI1_SCK` and...

@sixten9999 Good, happy that works. But a bit strange... In your example you chance the STM32F407 definition. And in your post you mention the STM32F401CC board. If you build for...

> The real problem here is the detection as STM32F407 by the code, making it choose the F407 code specifics, this is why it is falling to compile with internal...

BTW. The internal flash as eeprom for the STM32F401 might build fine, but it does not work.. The flash size of this chip is too small to support the firmware...

> Now I got the question, that is easy, it was defined wrongly before 202108, check [6179d4b](https://github.com/noisymime/speeduino/commit/6179d4b5aefebc650d758d0d86abcc81abd7a77d), pins PB4 to PB7 was defined to injectors outputs way before 202108. Also...

I have a long TODO item to make a manual how to tune open+closed loop. It really is not difficult and really works well to account for these type of...
