I never got this to work. I think there was something wrong with the 12V of the heater.Last time I connected the tinyWB it got super hot, even melted the solder. I turned it off and went to a local store and bought myself and AEM afr reader with the ls4.9 sensor and the problem was solved5peedmanual wrote: ↑Tue Dec 12, 2023 10:56 am Connected everything and reading is stuck at 10afr or 0V on controller output.

The board doesn’t have a voltage regulator so you need to use an external one. I used to power it from Speeduino but it would induce some noise on 5v so I now have a simple lm7805 dedicated for it
