I’ve noticed that my car has been running quite rich, including during idle, and dipping into 10’s on my wideband…
I recently moved my dangling IAT sensor when I reconnected my map sensor, which I believe is the result of this. The climate changes I believe are also causing this, since the past couple of days, it has been warmer than the day I tuned.

I'm running neptune...if i install the IAT, will the IAT compensation need to be recalibrated?
