You do need to care how the battery in 45e works. It was not designed to be fully discharged, for example.

I used to have flash tuner for my subaru back in 2007 and within a few minutes could tune/untune the car. Specifically untune if I needed to take it in to the dealer.

What is the process like for tuning and removing the tune for this Mission range mod? My subaru was plug in, press button, wait a few minutes, done.

Also, does the car record the tune/programming events in a log that the dealer could pull up if things go south?

They reset the counter. Taking into the dealer is not a problem. If they run a update then it would be deleted and I would call mission and schedule another session. I believe I have 3 sessions with the purchase but I don't think you are held to them if updates continue to happen. You can schedule to take off but to be honest the coding is no different then using advanced coding via E-Sys…

No, lithium batteries do not like being completely discharged. But still, it's the amount of energy that is available that determines how far you can drive. The kilowatthours are all exactly the same size from 0 to 24 kWh (if you use the full capacity of the battery). So if you use 24 kWh, it's only 41% more than 17 kWh. Not 100% more.

the original question as posited by motherkin was how does going from 17 to 24kWh usable capacity (41% increase) explain being able to increase the electric range from 30 to 60 miles (100% increase)?

[kingmonkeyjr]

One thing to note.. under charging sessions in the bmw app it no longer is showing my estimate of kWh for the charge. Looks like it stopped as soon as I got the range extender

[taybo20]

Are you getting solid real world results from driving electric only?

If the numbers are correct (24 vs 17 kWh), then it's impossible if the driving conditions are the same. You don't get a 100% increase in range with 24 vs 17 gallons of gas, either.

You keep saying 'they' and I know you mean Mission, but how is this done, remotely over the air? Do we do a webinar and they walk me through it? Thx!

I am not going to support the double range assertion without evidence either, but just to point out … electric driving and ICE driving don't have the same efficiency characteristics. Regenerative braking and non-brake speed control can have a relatively dramatic impact. So from the pure energy point, you are, of course, correct, but real life driving is not quite directly comparable between the two systems.

Teamviewer is downloaded on windows laptop, in need of a Ethernet to USB and Ethernet to OBD2 cables. You give mission a call and they log in to laptop via teamviewer. Flash took less than 5 minutes.

Have you calculated the cost of the flash vs potential savings?

$500 for the flash with gaining 20 more miles in winter and maybe 25-27 in summer seems like a great trade out. Those extra miles per day allow me to go further as I have had to use ICE lately. My mpg average over 1000 miles is 44mpg but have only used about 19 gallons of gas in that 1000 miles

[ThomasShelby]

Should be getting my 45e next week and will likely get this mod after break-in period and after I'm comfortable that the battery is performing as it should (ie. not needing to go in for repair) so maybe after a few thousand miles.

That said, since you're 'unlocking' more of the battery potential with this mod, is the performance (hp, 0-60, etc) increased proportionately as well?

Thx!

nope, performance comes from the electric motor. the mod just extends the range of the battery.

Does anyone know if the Canadian spec is 17 or 24? Based on internet it’s 24 and I believe they are built in Germany, but looking for confirmation from the forum.

What range was advertised for the Canadian vehicles? If it's in the 30-mile range (50Km), it's the same as the USA. If it's substantially higher, it's the rest of the world's. The actual batteries are identical...it's just how much of the capacity the computer will let you use. A bigger buffer, in theory, should allow for a longer life.

all X5 variants (actually all X3-X7) are built in the Spartanburg, South Carolina plant in the USA.

all 45e come with a 24kWh battery, but they're released in either of 2 usable battery capacities: 17.1kWh in the U.S., 21.6kWh in the rest of the world.

I thought I would a pose a question as pondering if one of vehicles ought to be a 45e. I’m one of those who keeps cars for long time .. at least 6-8 years. So I was wondering what happens in year 5 or 6 to the battery? How much would it cost to replace once modules start going out. I’m sure battery technology and charging would have undergone a big change by then. And I would be still charging it for 11 hrs a day.

the 45e high voltage battery is covered under the federal emissions warranty for 8 years/80,000 miles

i just had one battery module replaced after 1 year/4300 miles. cost: $0

**curious: why are you "charging it for 11h a day"? it the U.S. with 17kWh, if you're gonna keep the vehicle several years, it's more practical to invest in Level 2 charging @16A takes ~6h
