  1. 4xe speedometer calibration

    Z Automotive says it's compatible as per email excerpt below: Hi Jon, Yep, totally compatible. And once you change your tire size, then do a Full Reboot and two sleep cycles as described in the manual, you'll want to follow that with a 20 minute drive, preferably highway. Your sensors will...
  2. 4xe speedometer calibration

    About to get new 34" tires on my 4xe. Anyone explored speedometer calibration yet? Wondering if JL calibrators will work on the 4xe or whether this is a dealership issue because of the new tech.

    Having read all of the above, I still think this table I created provides decent guidance. That is, if you are driving around 60 miles in a typical day you are getting the equivalent of around 30 MPG factoring a fully charged battery. Not sure if you need to run all electric at first or not...

    Agreed. As per the EPA testing, 49 MPGe is only applicable to the first 22 miles of driving which is 1 mile beyond the 21 mile electric range. Every mile driven after that, the MPGe would go down and would go down pretty fast at first before sort of leveling out. I still expect that we will...

    I suspect your table does not take into account regenerative braking. Any idea what if anything this really could add to the math? Even without factoring that in, I don't see the switch to the EcoDiesel (25 MPG combined) until about 130 miles of combined city/highway driving. See my...

    The diesel would beat the 4xe on a 300 mile drive, but certainly not on a typical 10 to 40 mile day, and I would bet on a 100-mile day, the 4xe still comes out ahead.

    Rubicon weights 122 lbs more than a Sahara (+2%) so that should not be an issue. With custom bumper, a winch etc. maybe +4%. Should not be material to fuel efficiency. I think for 100 miles it will still be better than all other Wranglers by as much as 50% (i.e. 30 mpg vs 20 mpg).

    Any window stickers to report?

    The EPA data is really confusing, and we need to interpret it a bit. Just like my post earlier that there is no way we are getting 49 MPGE on a long trip, I also believe the inverse is true and the 20 MPG number is meaningless right now. There is no way that there is no benefit (i.e. just...

    This is definitely inaccurate for long trips. The 49 MPGe is either for the first 21 to 22 miles of all electric or perhaps a 100 mile trip (which would be fantastic news but I suspect not as per below). After that, you will trend down towards the 20 MPG number depending on the length of the...

    49 MPGe works for me. Hopefully, the Volta free (!) level 2 chargers next to my office (10 mi commute) will allow me to rarely pay for gas or electricity. Ship it already!
  14. 4xE Order Status??

    It looks like the end of the March for the start of deliveries is realistic with this MPGe update. Also, 49 is good news. I thought it was going to drop a lot from the 50 claimed in early materials.
  15. 4xE Order Status??

    Assuming the MPGe rating is the hold up and assuming they really are going to start shipping before the end of this month, then we should see an update to this page any day right...
