Support for Subaru EZ30 trigger

Does this one looks the same as some of 36/x/y triggers that RE already supports?

TS now can read livedata from 1f_rev2 wideband.
Next step is settings.

PS communication is over UART 115200. Next step is CAN.

Re: F103 Wideband Controller

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

Re: F103 dual channel wideband controller + EGT + 2 x AUX In + 2 Aux out

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...

VND14NV04 are pretty available that would give 12A :)
Available on JLCPCB? Or?
12A is good, but require adequate pin in connector. 12A over current connector can possibly vaporize pin :)

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.

Both outputs are capable to output in 0..5V range.
You can define any output voltage vs AFR curve.

I have checked the schematic, and I see that there is a lot of changes compared with f042 board.

Why not keep both boards similar into the LSU controller circuit?
We want to support LSU4.2 and ADV also.
We planing to add some SW diagnostic.
So some changes were added to support these.
