i dont know if its just after the car warms up for a certain time it changes or what, but cold start up idle the trims at averaging zero, go out for a cruise and come back and they are -0.50. i dont know why its doing this but if it keeps it up then i assume i should just do it for the hot temps for better idle recovery...any ideas?

 

I think it mostly has to do with the oil getting less viscous as it heats up.
