I know you will think this is crazy.
But.....
I plan to migrate into esp32-p4 and freertos ( esp idf environment )
Possibly add a small fpga for some front-end off-loading.
USB, Web-HMI, Ethernet, wifi, and native lcd display support.
Lots of memory and internal disk on flash.
Working on it.
Will be some major rewrites along the way, I plan in introducing some game-changers never seen before.

Re: migrate to esp32-p4
What feature would be added by esp32? Cheaper, faster, more robust? I'm not sure I'm understanding what features would be added. FPGA might allow more accurate crank decode or less jitter. However those don't seem to be a problem currently.
Many STM32's have a 10+ year mfg guarantee. That's handy as you can plan that you won't be doing major overhauling for years to come. Instead strained resources can focus on new development.

Re: migrate to esp32-p4
I want more memory, running web.servers, getting USB OTG, having USB that can toggle freely between host/slave.
Also I have invested time into P4
Freertos.
I am not asking for anyone to help, me I understand you rather not change a cpu, and I never asked for that.
But my personally i would rather use a more modern processor, that can drive a display , run a web-server and have internal disk, run a console for commands, etc,

Re: migrate to esp32-p4
I empathize with your goals. Personally, I use Microchip processors exclusively for my projects; mostly the PIC line. Seeing older processors still being used frustrates me. Since I'm familiar with the Microchip PIC offerings, I have in the past updated someone else's (freely shared) project with a newer, more capable processor. However, when it comes to the rusEFI line, I know nothing about the ST processors. Therefore, here I'm just a user. Good luck with it, though.

Re: migrate to esp32-p4
Why to run web server and real-time applications on the same cpu?
Why connecting display directly to ecu? We have open source dashboard that perfectly interact with rusefi over 2 wires of robust can bus. Esp32 can drive only parallel bus to display. This is 10+ wires of low noise immunity parallel interface.
Why do you need usb host? BTW stm32f4/7 has two usb interfaces. One can be used as host.
And esp is definitely not a more modern processor. It is more specialized.
