My 2021 Mach-E received 91 kWh upgrade (useable at 100% SoC)

[Mach1E]

I'm confused... but happy. I've had my MME (LR-RWD) since late March this year and, until yesterday, have never had a displayed range of more than about 300 miles when charged to 100%. I tried resetting the range calculation thingy but it made no difference. Yesterday, however, after a visit to "Peoples Ford Edinburgh", my displayed range jumped to about 370 at 100%, i.e. pretty close to the published figure of 379. Not only that, but I'm suddenly getting about a mile of real travel for each mile of displayed range, whereas before it was more like 0.8 mile travel per mile displayed. What's happened? Does the dealer have a box of extra miles that they stuff into a socket somewhere?

Must have warmed up in Scotland.

The speedometer is programmed to display exactly 1 MPH fast (due to federal law), but the odometer is accurate. So if you set the cruise at 75 MPH the odometer will increase 74 miles in one hour. From now on, you will have to set the cruise to +1 with this knowledge. ?

I did notice that my actual speed is 1 MPH less, but I didn't know it is federal law. What a stupid law.

When I replace my tires, I am going with 255s instead of 245s, which will mean my speedometer will finally be accurate. But the odometer won't? That is messed up. They should be in sync.

I am unsure of exactly which update unlocked it, but after applying all updates in FDRS, my car now has 91kwh useable at 100% SoC.

I did reach out to a contact at Ford and got permission to share that yes the car does in fact have 91kwh useable now. However, the extra 3kwh has been added as a buffer below 0 on the GOM so that you can still drive a short distance after 0.

I thought I'd start a discussion on this as it seems to be a weird way to add in the extra capacity. It feels like the people that made this decision were trying to make it more like an ICE vehicle where you still have some range after you hit empty. However, I don't think EV drivers are normally driving their cars past 0 miles and would much rather have this capacity in the normal useable range.

What build date is your GT? I was just at the Ford dealer to buy my 2022 Route 1, and I walked over to the service area to ask what updates were available for my wife's GT. I was told there was only the recall update available ?‍.

It's a September 21 build.

it's likely the usual suspects of summer weather and driving patterns.

They are either lying to you, or have no idea what they are talking about. Maybe find another service dealer.

Go to the FDRS VIN lookup thread, and someone will check to see how many updates are available for your car. Mine is a August build, and I had a ton of updates my dealer did in February. Now I have a ton more. There is no freaking way you have no updates available.

Did you get the better charging curve and expanded capacity update? Since I do all of the charging for my wife (all public since we street park), I really only care about the damn charge rate improving above 80% lolol

Absolutely. The update I had my dealer do on February 7 gave my car the better charging profile and the increased capacity. So if you have your dealer do all the open updates now, you will definitely get those.

Thanks for confirming! I'll try to get this done next week lol

Keep in mind the updates could take 4+ hours. That tech time has to be paid for by somebody. They might not want to do it for no cost. Which is probably why they told you no updates are available. They were really saying there are no updates they can apply at no charge to you.

If you have a problem with the car that has been reported to Ford CS with a case number assigned, and a software update might fix it, they may be able to charge Ford for the updates. Otherwise, I think your chances are slim.

A buddy with a 21 Job 2 Select just got it OTA in the last few days.

The OTA will not give you the faster charging speed or additional capacity, I don't think. But I could be wrong. I guess we need a few people to get the OTA and see what it does. My bet is the OTA is just for the recall and has no other improvements included.

His car scanner shows usable energy to empty 71 kWh. It was 68 a few days ago.

Yeah, so it appears I was incorrect. In another thread it has been confirmed that the recall update includes prior changes that include the charging and capacity improvements.

So look at that! OTA is giving people real benefit! Not just covering Ford's ass. ?

71? The SR battery was only supposed to be increased to 70. I hope they didn’t OTA him the wrong battery. ?

Again, haven’t seen anyone go 25 miles on the first %.

But even if they did, if it says 99% and range 300 miles, would you really try to do your own math to get to 2500 mile range?

The reason people say “don’t trust the GOM isn’t because it isn’t accurate.

It’s because it’s a GUESS based on many moving variables.

It could “guess” 300 miles range. But it doesn’t know if you are about to drive 110 mph the whole way or go 5 mph the whole way.

And neither do you! You could “hope” to cruise at 70 mph and then you hit traffic. You seem to want to do a bunch of calculations predicting range but they’re entirely unnecessary.

You also aren’t going to use all the range anyways. Most will charge with around 20% remaining.

And again, accuracy of it being 99% or 100% charged doesn’t affect any of this.

The GOM has to be derived from the basics consumed/traveled and some have used a gas gauge and an odometer (seen the trip in this one not accurate on the unconservative side odometer appears good) for over 40 years. Not much math if you start at 100% and travel x miles in the first 20% how far can you go when you hit 20%? MME makes that a bit more difficult and the answer is not 4 times. A linear scale being linear would be an improvement.

I see you are not interested in physically trying it to understand. You just have not seen it go exactly 25 mile? Run the first percent and add two zero's math is not that hard for that.

I think these forums prove that people complain no matter what.

Or just what someone thought was a glaring bug and should be an easy improvement that could be put on the list got all blown out of proportion. Just another machine and this one has a few glitches. User here no fan boy. Hoping ford is looking to improve. Time will tell and minds made up I guess. So far them fixing their mistakes has been top notch .
