ECT was 50 upon ignition (ambient temperature) and slowly rose til it peaked at 192. Never budged from 192 once it got there, even when I got to my destination and idled for a few minutes. Seems normal since aren't the thermostats 193?

IAT was @ ambient temperature til I got to work and idled. Jumped like 20 degrees in a 3-4 minutes, lol. All normal

SFT was noticeably lower this time. ~1.16-1.21 on initial start up, but dropped slightly to 1.10-1.19 within a minute. A mile or two down the road it further dropped to roughly .99-1.06, and hot idle was a tight .97-1.02
