I asked him last night about those Man_P and Man_V and he said they weren't hooked up, so not sure what they are or what they were measuring..

It was raining on Friday so he did hook up the air plenum to a vent that pulls air from control room where he had a window A/C unit running. It wasn't very cool in there but the air was much dryer, he said pulling air from outside with the rain would be pointless as it would never run in the rain.

I was thinking Man_P was air fuel ratio but I guess not.
