It's low enough for me to wonder what layer is broken. https://github.com/rusefi/rusefi/issues/4203 is somewhat relevant

Re: Subaru SVX with custom RusEFI
Engine was rebuild. Then I had a problem with PCV, that costs me engine out and in again and set of gaskets. Yesterday I done my first ride on RE this year. Today it is +30C in Saint-Petersburg and I need to figure out why AC is not operational with RE. Compressor clutch is not get activated. Wiring...

Re: F103 dual channel wideband controller + EGT + 2 x AUX In + 2 Aux out
In high level motorsport applications, they make Chromel / Alumel contacts for Autosport connectors to maintain accuracy. I suspect in this case the difference would be marginal over the required range for exhaust temperature measurement, its also very easy to add an offset in software. Might I sug...

Some issue with fitment. Thanks to plastic enclosure you just need to push it harder. Acceptable result for development with no enclosure on hands.

If you build such a big external Lambda-/EGT-controller, it should be as universal as possible and work in all possible ecosystems, also out of the rusefi-world. This means: -data transfer to ECU via can bus and also via analog out. Every lambda controller should get its own wideband analog out 0-5...

Re: F103 Wideband Controller
I was thinking about it. But...
Heater in between of 2 and 2 signals is not good for routing.
So heater was moved closer to 12V and GND. This also shortest high current routes.
