I agree with @
- this looks like a mismatch between TS project version and firmware version. Theoretically the best practice is to re-create TS project every time you update firmware, and also to use matching console with it.
There is a bit of usability issue here for sure. I've actually started working on https://sourceforge.net/p/rusefi/tickets/309/
only for console but you made me realize that TS situation could be improved as well. Let me see if I can implement a unified solution for both console and TS to detect incompatibility better.

The part about not working SD logging surprises me.
I am still suspecting that Rev C and Rev D and same exact
hardware - I believe the incompatible change to ST Link firmware is the difference. And I believe that updating st link firmware in the discovery is pretty much making Rev C board a Rev D board. And just a reminder, default Rev D firmware is the one from "rusefi over-current" problem so I am now flashing latest discovery firmware into the boards I sell.
With that in mind, I cannot explain lack of SD logging. I would say once you have time to look into that I would upgrade both boards to same discovery firmware, same rusefi firmware and settings. If they do not behave the same I would claim hardware issues. I would love to be wrong in this regard.
I am planning to solder the first of https://sourceforge.net/p/daecu/code/HEAD/tree/Hardware/trunk/rusefi.com/brain_board_STM32F407_SD_wing-it/gerber/brain_board_STM32F407_SD_wing-it_3.png?format=raw
today to validate that little thingy and ship it your way with a D board.

You might not like what I say now: you are the 95% of real vehicle testing these days. Both Lemons race cars are work-in-progress getting ready for the new season - the yellow race car is not street legal so pretty much driven three times a year. The green race car right now is a tub with no engine, no suspension, no spindles.
Most of my rusEfi time is focused on making Frankenso full bundle look better. I hope that with better usability and slightly sexier looks there will be the critical mass of NA miatas. I am semi-actively looking for a pre-95 Miata already.
