Just tested Shutters operation with update and they (FORD) raised the temp for opening from 190degrees to about 210degrees for slow speed and 215degrees for around 60+mph. Seems to be pretty much open or closed instead of steps. This explains why Grill Covers are running 10degrees hotter than before update. Also this would explain why this wouldn't make a difference with cold operation, because Shutters weren't opening anyway. Also HWY MPG's would improve a little keeping the ICE warmer and more efficient. There might be a slight Aero improvement too. During testing temps were 54degrees and I had great difficulty getting ICE temps up to 216degrees, it took about 12miles on FWY at 70-90MPH for my 14mile loop. With Grill Covers on it took just a few miles. I did some experimenting with my Grill Covers on my trip back from AZ with cutout Grill Cover and Full Grill Cover for ICE temps and MPG's. With outside temps between 38-66degrees the Full Grill Cover ran between 217-231degrees and Cutout Grill Cover 207-220degrees. To my surprise I didn't see any noticeable difference in MPG's, I was changing them back in forth about every 100miles. I'm wondering if FORD has changed the ICE operating temp with the Shutters not opening until 215degrees. The Operating ICE temp was 202-212degrees. I have some more LEXAN to make Grill Covers if anyone is interested. :) Paul
