Thanks Joe.
That can be done in the map currently with
# 0 = None, 1 = Inp1, 2 = Inp2, 3 = Both
MyECU Cfg O2Sensors=0
It could be added to the Optimiser to be more convenient.
I'm currently redoing the PCBs using something more sofisticated then the old manual layouts I have done. I'm using
https://easyeda.com/ which allows me to work at schematic level. At first the new boards will be functionally equivalent.
I'm also working a new version of software that is using FreeRTOS to tidy up some of the bare metal code. I run this on my Breva. Again this is functionally equivalent to the current software.
The idea being to one day move to a more powerful processor, perhaps an ESP32 with builtin bluetooth and possibility of Lua coding. That's a long term project.
