    The new HV Range fix works well. Before this would have said 80 mi remaining or something (about 0.6 gallons left). My wife was pushing it closer than I would have ;)

    Good to know. We had the fix done a couple of weeks ago but haven't used any gas since then so we don't have any data like you do. Thanks

    After the fix I took a 500 mile HV trip where I got 49 mpg. Back home with a fill up, my HV range estimate is now 322 miles (was 357 after fix)
    So 322 m/7 gal tank = 46 mpg so this looks like it’s working fine.
    I have now officially resigned from the Honda Club of Unlimited HV Milage.

    Does anyone know how to tell if it has the fix ? I'm picking up my car on Tuesday and it would be nice to verify.

    I'm at dealership right now waiting the software fix. My current HV range is 661.i hope when I get it back in few hrs it will say more like 250 or so.

    If your tank is full, my crystal ball predicts you’ll get it back with 357 HV range estimate. Let us know.
    PS: What’s your Glock # (mine’s 19)?

    Consumers can see the firmware version of their $500 cell phone but not of their $30k programmable car. Safest thing is to tell them about the service bulletin and ask if it has been applied. Strange that this SB doesn't have a range of VINs for which it is necessary. Is that not something they would normally do?

    Agree, ask them to apply the SB before you pick the car up.

    HV fixed. Took about an 90 min total. I drove in with 661 range and now showing 305!

    In case anyone was interested, Service Bulletin for HV Range attached.
    I live for the various and sundry technical bits.

    So if such tools as this i-HDS software and J2534 software and related equipment become available on the dark-web, Clarity PHEV users might be able to tune their cars like BMW i3 users can and @bobcubsfan could get his daughter's ex-boyfriend's landlord/mechanic to program his to never activate the ICE.

    Ask @bwilson4web about reprogramming an i3.

    Put about 2k miles on HV range fix now, it is perfectly reasonable now (still can overestimate some, but much closer, like within 10%).

    A note is that it never seems to increase. For example, I drove up a steep mountain pass and it dropped from like 270 to 210 miles, then long steep downhill after and I went another 70 miles or so before it moved from the 210 estimate and started dropping again.

    This is normal for some cars, no big deal and won't get you in trouble like before.

    Anyone else ever see that the gauge takes a while (minute or two) to show full after filling up? Not sure if this was related to SB or not.

    I don’t consider it fixed when I and several others can drive 25-50 miles, observe the graphical gas gauge drop 2 notches, and yet have zero change on the numerical HV estimate. It’s better than before, but something is still obviously wrong.

    So some of us are getting very different results.

    I'm hoping to take delivery in a couple of weeks. Should I expect them to apply this SB before delivery? Or better have them do it and document so? Don't want to have to schedule time off the following day for them to apply it.

    I have had other cars do the same, it refuses to raise the estimate is all, so until the estimated range drops below the new range estimate it stays fixed at the last reading. Not my favorite way, but not the first car I have seen do that.

    It seems to take forever for the gas gauge to change now.

    I noticed it for the first time a few days ago. This was after the 'range fix' was applied.

    Anybody in Southern California get the fix applied? I went to my dealership (Metro Honda in Montclair), and they could not find the update in their system.
