Stm32F4x1 or STM32F407?

Would this work as an alternative?

I tried to compile under F407, but there are a lot of errors in the Arduino IDE. I wonder what's wrong?

Did you check the instructions to compile with Arduino IDE on this thread. You also need to install few libraries.

But easier is to use PIO. Instructions at wiki: https://wiki.speeduino.com/en/Installing_Firmware

Here is the compilation error:

Has anyone run speeduino on a stm32f767 yet? I'm looking at a nucleo board on my desk, looks awesome, so I'm wondering why it wouldnt work? I pretty sure Rusefi will run on it and I am having this idea of possibly building an ecu that could easily run both.

the 407 already can run both.

Hi, I am using the STM32F407VET6 board (a classic black one from aliexpress) and it works fine with tuner studio. Now I bought a second one, flashed with the same files, and tuner studio shows maximum values of IAT and CLT, everything else is fine. Grounding the pins did nothing. So I bought another one, thinking this one may be faulty, and it's doing the same.
Any ideas?

[jonbill]

have you calibrated the sensors on the new boards?

As @jonbill mentions, you need to recalibrate. Though the calibration is stored on the board, it is not part of the tune.
