I'm really confused why people say that an F103 has limitations that can't be overcome. The only thing I've ever seen someone claim as a limitation is that it doesn't have an EEPROM back in 2018. ST has Arduino code examples to read and write the 64/128k storage over serial. What do you think the maple mini boot loader does? What would be the other limitations that would prevent it from running a motor when a 16MHz 2560 does the job just fine?
I would try to use the maple mini firmware with USB virtual serial com. It seems to be more reliable than a UART adapter when dealing with Arduino. You can flash the maple bootloader over serial then use it without the serial adapter to flash your F103. It has to be rebooted before each flash. Another option would be to use a Nucleo board with STlink V2-1 that opens a com port through the STLink.
It won't connect to tunerstudio if it doesn't connect to the Arduino serial monitor.
I'll try to get the firmware compiled when I get some free time, seems like a fun branch of speeduino with $1.40 boards. I could see it being used as a spark box, or even as a brain for a batch fire TBI system like the Holley Sniper that's becoming popular.
