Any changes on PIN-6 ? or PIN-10 (if present )
I can detect the battery voltage > 13v to know when the engine is running. But, I still do not know how to tell when the IGN in in RUN or ACC.
This would be fine, except that I think people would want their gauges to turn on, with the key. I know how to make the gauge wait until the engine starts, to start heating up the sensor. And, I can, eve, let one of the gauge buttons override the wait state.
My worst case scenario is to wake the device up, once, every second or so and, query the ECU state. Then, go back to sleep... Functional, but, not a good look
