Hi all petrol heads

I'm trying to get EGT to work on Uaefi, but I cannot get a reading form the sensor. Anyone able to help? I have the hardware on board for it to work. See picture. Image

The schematic states SPI3 with CS pin PA15 Image

Tuner studio settings Image

Cheers

Hello,
How did you activate SPI3?
We have a microrusEFI and want to use 3x MAX31855.
I cannot set the pins in Tuner Studio for SPI3 nor enable SPI3.

If I enable SPI4 the message says it is not supported on the RusEFI.

I soldered test leads to PC10 PC12 and PB9 on J4. How can I activate SPI and connect the MAX31855?
