Man i love seeing these temps. With my stock ic i was getting upwards of 120-130 at cruising in 90+ degrees ambient.
When stopping at a light, the IC isn't providing any cooling and your IAT should go significantly up. If you P3 was reading ambient, it could go up at a stoplight because of the extra stagnant heat from other cars and the road surface.
I will post my log from this am. Air temp was 75-77 and my IAT on the highway was around 82 then jumped to 108 when I parked and let the car run for a couple of minutes.
RPM is on the right axis.
Speed and IAT are on the left axis
The temp in my garage was 89, and I had the car running a few minutes before logging (with the garage door open)
