Nathan Shih noticed same thing nice catch

I'm about to do the same... Tired of BMW service resetting things and me having to track down "my guy."

I need help for some reason the rang extender option is not there

I coded the chimes off for the seat belts and I can't say I miss that annoying noise

Mike, that's correct. It's suppose to do that man. Ignore it

@@JWard2 Hi J. you didn't understand me... the head unit stopped all functionality. Like I said I was able to drive the i3 but that was it, until I re-code using the back up to regain control. is there something I missed?

@@mikemchale7639 o the head unit froze!? And would not work at all until you took it in the dealer?

Mike, the units of measure are in hexadecimel, and in increments of 0.5, so if you used expert mode and tried to change when the unit comes on to 10% of charge, you need to use a hex converter, and enter the appropriate value for "10."

John Teichman thanks! The port’s on the underside of the dashboard in the driver’s footwell about where the headlight switch is.

Good to know! I was just considering making the upgrade myself, but will now have to reconsider.

felisaaero what no way

Who can I get some help on this with I have a 16 model

felisaaero okay so the coding is still adjustable but just requires another device to access the ECU?

Kevin Cummins did you figure this out? This is happening to me.

If you didn't figure this out, yes this option is in the app

Kirk Turkey I think the gas range was optimistic when it first reset. I’ve seen the range estimate change wildly with weather and driving history, but usually I get about the same 75 mile estimate

MANDOCAMMANDO I think it should work. The screen size doesn’t make a difference

Anything above 70 or inclines and the battery will slowly drain, AC too, although I didn't notice much difference. When driving a full tank empty on the highway I'm used to seeing the battery drop maybe a third or half a bar. So if you're planning on a cross country trip with no slow speed driving to give the generator time to charge up, the battery will definitely drain. It's a shame the rex can only be set to maintain charge and not increase it. Also, the cooling fan will run a few minutes after parking and that seems to drain the battery a bit too.

oh yes, it works for me.. after a while at that speed with ac it may go down to 70% or less but it really doesn't limit your range, except after 70 miles you will need some gas.

Thanks, also assuming in a pinch you could just pull off at a rest stop and let the rex run to charge the battery for a bit?

I am able to maintain 74 on my REx and remain at the same battery level on level ground with no A/C. My car is a 2017, and supposedly the Rex makes a little more HP than 2104-2016 models. With the hold mode (like in the video) though, you can engage it at 75% battery. At that point you can maintain any speed the car can go, it's just you'll use some battery. Much less than you would without the Rex running. So you might drop from 75% battery to 65% battery over 50miles of driving at 85mph. It's still not the car I would choose for a 1000 mile trip at 100mph, but that's why there are rental cars...

One thing I've noted is that you can turn on your cruise control/auto distance control, and not actually set it. Just hit the button to activate it. With it activated, you can change your "mode" down to Eco Pro + (the lowest) and exceed the normal 56 mph restriction. If I'm really concerned with distance - ie. super late at night - I can stretch out quite a few more miles that way. Along with the range extender and being able to turn on the "hold" mode at will, it gives a fair amount of flexibility.

Jerry FromUSA I did a 1000 mile trip on the REx and I haven’t had an issue yet. Actually driving with the REx on more seems to be good for the car and I’ve had fewer CEL or ‘drivetrain malfunction warnings’ since coding. Most forums say it’s hit or miss with the service centers. The backups get the ECU’s back to stock so usually it’s not a problem. Of course any coding beyond of what the car was made to do could cause legit warranty voiding problems so I wouldn’t do anything the car wasn’t designed for.

yes

It's a G.O.M, so it's trying to calculate how far you can go based on your driving style, and probably other things like temperature and maybe battery health. If you hyper mile for a a few drives you should see the number of miles you can drive increase as the G.O.M does its recalculations

What do you mean?

A lot. Turn on your lawn mower and put a pillow over it

HI Lowko, if you are on the FW, say going 70 you can hardly hear it! Say if your going up a steep grade you will hear the rpm increase & get considerably louder

Too loud. Sucks.

Nope 2019 won't either

Code the gas tank to increase capacity and then turn off the heat or air conditioner to see max range.

John Edwards i don’t know, but when I code the tank to 9 liters, my electric range says 90 miles and so does my gas range on the Rex.

John Edwards too bad I can’t send you a photo of my instrument panel showing what I’ve stated

I think there is yes.

Gavin Critchley thanks!

Yes, you can set up a max speed

No it will not.

@@kevinc2683 thanks for your help

Derrick Snell Yep! All in all the app and OBD II adapter cost me around $50-60. Having my own adapter was a good investment too, cause now I can inspect fault codes which can happen fairly often especially when using the REx.

Code changes allow you to access services and features that, by default, are (for various reasons and regulations) are turned off. Some (US) disabled features are: AM radio, watching movies on your iDrive display (great while sitting and charging your car), changing your tank capacity from 1.7 gallons to the complete 2.5 gallons (the US restricts full capacity for EV/eco reasons), activating HSOC (hold state of charge) which gives you the flexibility (under 75% battery) to turn on your REx (range extender). For long commutes, HSOC is good when I'm looking to get the best efficiency-- using REx on the highway when I know I'll have little regeneration ability.

Neal Hill thanks so much. This is really helpful. I would like to change some of the codes but afraid to mess everything up.

There are professionals out there that can do it for you... Of course, you have to pay for the service

@John Edwards Yes, I'm having issues. My HSOC is ok but my tank capacity was changed. This is the second time it's happened. It's a pain hunting down a "coding guy." So I'M gonna be THAT guy. 😝... I just ordered cables and coding software. It's should arrive tomorrow. I'm in I.T. and am comfortable with hardware, so I'm going to put the changes back in.

We have one...husband is 6ft about 250 is comfortable in it and drives it just fine...I don't think you will have an issue...also in the test drive I sat behind him because I wanted to check the room and I had plenty of room but I'm only 5'2"
