I bought 4 MRE from Dmitry Korostelev as well as 4 "Speeduino Blitzbox" for test use
"considering shielding the community from you" - SOUND VERY RUDE. I dont deserve this...
You have 4 MRE.
I am blunt and that could be border line rude, I have to accept that.
I would like to request that your next post contains a video of MRE opening ETB very quickly with a corresponding log file showing quick change of TPS.
In the current case I do not see how we would have space for it. There is not 1 square cm of the current MRE that does not have functional circuits on it.
My idea:
SD card can be placed on any "extended device" - flexible extender etc.
(is any 8pin header usable for it ..?? with SPI interface)
BT comunication - I have lowcost BT to TTL (HC-05) on my VEMS
We need 4pins, VCC RX TX GND for hardware ...
and software support - no baundrate change when we communicate ..
(thats all)
(I don't have MRE on my desk to test it ... at this moment)

Those should both work. The SPI expansion header is all that's needed for an SD card to work - just MOSI/MISO/SCK/CS and power (3.3v). There are also exposed UART pins that should work with a normal "passthrough" bluetooth module.
Diodes on back side D6 and D20 are so close to bottom cover (black plastic case)
The 0402 Caps and Rezistors are soo close to other pins, (and too small to solder by hand, also )
Is able back traces for caps & rezs arrays to back side ..?? (on next PCB version .. ?? )

Attached are custom gerbers modified to use U-M-M5DD-W-4 USB vertical connector. USB connector orientation is different which is fine, open question is if USB is functional.
If you connect the ECU over USB before applying external power, it should appear as an SD card reader to your PC, so you can check functionality that way.
