How do you guys wire this darn thing? There seem to be conflicting requirements.
1. Don't power the sensor until the engine starts, or cold condensation may damage the sensor.
2. For calibration the unit must be operated in free air, and obviously powered. But how do I wire it for calibration (engine off), and for normal operation (engine on for #1)? Not simple.
Also, I assume you guys are not really calibrating in "free air". That would require removal of the sills and the sensors. Are you just calibrating after waiting for the exhaust to clear out?
