I will do the measurements. I have some CO2 sensors.
This doesn't help with the recirc temp problem, but if part of the problem is fumes and smell, then this Pureflow filter fits perfectly in the MachE and does a good job of filtering incoming air, much better than the dust-only filter the car comes with. https://www.amazon.com/gp/product/B08Y8J86BH/
I installed the Purflow, works far better than the original for sure. Not quite good enough, I am afraid. I am spoiled because I have driven with outside vents closed in every car I have driven in the last 50 years (except when driving in the mountains or along the sea shore).
Although I’ve not yet taken delivery, this is discouraging. I’ve always used recirc whenever behind a diesel or oil-burning ice, and either disable it or turn on the AC (with comfort temp set) to deal with any subsequent fogging. Why take these decisions out of drivers’ hands?
Do you have studies on this by chance? I don't think our vehicles can be considered "sealed" when there are external cabin vents (behind rear bumpers?)
Curious what your build date is to see if maybe some of the heating issues are Job1 cars.
Everytime I go to the car, i mean to check the sticker.....
Took some measurements. Over 3 days, half hour drive 2x per day, I got some interesting results. Keep in mind, that currently, I can tell within seconds when the car decides to let in cold outside air and I turn the recirc back on. About half the time, the CO2 went up 3% or less (about 20 ppm out of 700 ppm), the other half CO2 went down the same amount. I see more variation during the day in my house measurements. I did not see "CO2 rising rapidly" at any time. There seemed to be a bit of a correlation with the rise times occurring in heavy freeway traffic but that also correlates with an altitude change of over 700 ft and travel from seashore to low mountains where I live. Not very scientific and I did not log the results. I did verify to my satisfaction that continuous RECIRC did not adversely affect air quality inside my car to any significant degree or consistency. What does not make much sense is @Ford Motor Company deciding to blast me with cold and bad outside air every few minutes and me having to fight the car for RECIRC control. It is a distraction while driving that is potentially more dangerous than tiny variations in cabin air quality!
Well it definitely seems to lean towards shutting off quickly. There needs to be an Auto function and a lock function. If I’m driving through Newark, NJ, I don’t want that stank coming in the car. I’ll deal with fog. Come on Ford!Unfortunately, it appears that it was intentional. But, hopefully, they will update the software at some point to make it a little less aggressive.
