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 this context it's about RC models, is it still scary in case of RC?

BTW: ..
how about a BT communication .. and external SD card on MRE .. ??

..it is possible ..??

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.

I'm try to complete parts list for my mre boards and I have some hits ...
..for less parts sorts ..

C39 same as C43 22uF 25V 0805 - to same size
R28 R48 2.2k to 2.7k ..?? (It can be 2.7k .. ?? )
R22 120ohm ??? can be 100ohm ?? 1206

R10 1kOhm 1206 .. where is it ..?? (I can't found it on scheme)

U7 XC6206P332MR can be AP2210N-3.3TRG1 or MCP1700T3302ETT

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.

Now I'm try to connect sdcard on my mre ..
related to https://rusefi.com/forum/viewtopic.php?p=36526#p36526

Have small sdcard adapter, piece of cable "from trash" .. (from old DB25 bracket)
rusefi console says CONNECTING ...

It is good .. ?? or it must be "CONNECTED" .. ??
(I have no other rusefi board to compare ... )

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.
