  1. Horrible efficiency on recent trip.

    We get a lot of snow here in the winter (I live near one of the snowiest cities in north America). We don’t get extreme cold (the lowest I have on my home record is -15 degrees F). For me, I think it’s a combination of a lot of experience with high-efficiency driving and high elevation...
  2. Horrible efficiency on recent trip.

    You stated you stopped for breakfast after about an hour, so presumably you started before dawn, or at least early in the morning. So… It was probably colder than 50 degrees F, given that you’re in upstate NY in November. That lower temperature almost certainly cost some energy to warm up the...
  3. Frunk Space Heater?

    I would use a seed heater or other thermostatically-controlled mat on the inside bottom of a box or old cooler. But I would power it from a small lithium power station that’s charged from the frunk outlet when the truck is on and runs the heater separately. This separates the truck’s batteries...
  4. Storing Lower-Cost Energy in Your Lightning to Power Your Home and Returning Power Back to the Grid

    Planetary scientist who studies thermal systems here. Nuclear winter would do it too. :/
  5. Storing Lower-Cost Energy in Your Lightning to Power Your Home and Returning Power Back to the Grid

    There are so many limitations to using the truck for automated battery backup that I would rather spend the $5-10k on a whole-home battery backup that’s always available. We currently have 24 kWh of backup and 14 kW of solar. We rarely use grid energy and often sell it back at the most expensive...
  6. AZ Camping and Towing Experience- Gilbert to Sedona

    We’ve been to 10 states in our EVs, hoping for another 10+ next year, depending on various possibilities. Here’s an out-of-date map of our road trips. https://www.f150lightningforum.com/forum/threads/adventures-of-our-2023-carbonized-gray-metallic-lariat-lightning-er.19238/post-454475
  7. AZ Camping and Towing Experience- Gilbert to Sedona

    It depends on which direction you go once you get to Flagstaff. Going east on the I-40 for 60 miles takes you to Winslow with both an EA charging station and a Flying J charge station. Soon there will be one at the Mobile on Meteor Crater Rd between Winslow and Flagstaff. There’s a 130 mile...
  8. Connecting battery tender

    I’ve run exterior-grade 20A extension cords through the frunk front closure. It closes just fine and doesn’t leave a permanent mark on the extension nor do any damage to the frunk gasket. A small gauge trickle charge cable running out of the frunk would have no impact.
  9. Lightning Software Updates using FDRS

    Well... The SCCM setting was at 2. Must have been reset in one of the attempts to reprogram it? I changed it to 4 and the DTC has, at least for the moment, not returned. Thanks!
  10. Lightning Software Updates using FDRS

    Thanks. I have a meeting. Will try later this afternoon. Hope my subscription isn't ended.
  11. Lightning Software Updates using FDRS

    I did that one a long time ago. I didn't notice the DTC back then.
  12. Lightning Software Updates using FDRS

    I originally said, “No.” It failed. So I tried with, “Yes.” It also failed.
  13. Lightning Software Updates using FDRS

    I didn’t change anything in the SCCM directly. I have not done the heated steering wheel (it came with it and that has always worked). I can’t think of any of the “shortcuts” in Forscan I used that would have changed anything. What’s currently on AsBuilt is identical to the configuration in the...
  14. AZ Camping and Towing Experience- Gilbert to Sedona

    Payson’s EA station is a great hidden gem charging spot. It’s never been busy when I’ve used it when I want to avoid the chaos of the 17 going north from Tucson/Phoenix up to Flagstaff and beyond.
  15. Lightning Software Updates using FDRS

    No go. The PMI fails. I’m worried I synced the truck’s configuration to the online database. I think I might have to find a ’23 Lariat ER AsBuilt that hasn’t been corrupted. I got complacent this time and didn’t make a record of the changes I made.
  16. Trail Turn Assist?

    I updated all my modules, but the trail turn assist toggle still doesn't stay engaged. Bummer. I wonder if some other setting in the ABS module needs updating.
  17. Lightning Software Updates using FDRS

    Question: After a bunch of updates, clearing codes, retesting, etc, I have one remaining orange DTC: SCCM configuration incompatible. The SCCM configuration is the same as the AsBuilt configuration. Any suggestions?
  18. Lightning Software Updates using FDRS

    I finally got in. But I'm not sure I'll have time to update both vehicles. Still running the truck through... There are a lot of updates.
  19. Lightning Software Updates using FDRS

    Yeah, I have all three versions downloaded (45.5.8, 45.6.8, and 46.5.4). 45.5.8 expects a code; 45.6.8 allows either a code or a subscription; 46.5.4 allows a code or subscription. None let me log in with my subscription (I did not get a code when I bought the subscription). Still no...
