Q: I see Frankenstein has a USB serial adapter on it. Will I be able to communicate with the ECU without that particular port?
A: You can use any $2 USB-UART from ebay to replace the FT232 functionality (worth noting that CP210x have lame reputation, I know from my own experience that CP2102 Windows 7 drivers are giving me BSOD too often), you can also get away with just the micro-usb on stm32f4discovery (worth noting https://sourceforge.net/p/rusefi/tickets/46/
) See also: viewtopic.php?f=5&t=210
"m3 standoff" that's what these are called... gotcha
Attaching stm32f4discovery gerbers so that later I can open them using http://sourceforge.net/projects/gerbv/files/gerbv/
and find the best spots to drill...
