How many more mpg are you guys seeing with xDelete turned on (rwd mode)? Especially on the F3x series.

When I was using it - it was significant - my guess mileage shot way up - it was staggering to me.

I've been running xDelete for almost 6 months straight now; even through PA's "winter". Definitely noticed that my tank of gas lasts longer than with xDrive on. Unless you've never driven a RWD car, pretty much most BMW's lol, you don't need to worry about being in RWD, it's just a different mind sight of driving you have to do. LSD just got installed so gonna stay RWD for a bit longer but honestly really curious to see how this car handles when pushed hard with xdrive on with limited slip

Did you go with the M performance lsd? curious to hear how the car feels in RWD with a real lsd installed! Also I can agree our winter this year has been pretty lame! lol

I am shopping around for an obd2 adapter to work with xdelete and I am having some issues deciding the best to buy. I am from Canada.

I could buy the wired obd2 adapter and the iPhone adapter for about 60$ from Amazon or the MHD Tuning Wireless obd2 for about 120$ from Burger Tuning.

For the wireless adapters, is the MHD the only one that works with xdelete or can I use any other one?

Yes M performance! I bit the bullet when I came across one for a "decent" price (wish I wouldn't know ECS was selling them for 500 a month after I bought my car..) I haven't pushed it too hard but it's noticeably different and puts all the power down; truly transforms how the car feels. Really need to push it to its limits though

I have an obd2 to ethernet cable that i used with bootmod3. I bought a lightning to ethernet adapter to use with my iphone.

Hooked it up to the car and the xdelete app detected my car just fine.

Now to wait for a sale...lol
It’s still winter by me so I can wait. Should’ve jumped on it during Black Friday last year.

A few pages ago, there was lots of discussion about the AWD version that XDelete uses for when you revert back to AWD...specifically, the argument is that it's not the same as your OEM xDrive programming which could theoretically make it suboptimal in some way. Maybe it's too generic (for example 40% front, 60% rear) or maybe it's an OEM version pulled from a random test car several years ago when the app was being developed that may be different from your car (coupe vs cabrio, 4cyl vs 6cyl, AT vs MT, square vs staggered, etc).

While I get that this is theoretically concerning...has anyone had any real world performance issues when switching it back to AWD?? To put it a different way: is this just a mental exercise (albeit probably a good one to have), or has it panned out in any significant way to justify the concern?

I'm seriously considering getting XDelete, but this [probably insignificant] issue is weighing on my mind to a small degree. Everyone raves about the RWD performance so it's probably worth the improved/RWD performance 9 months/year to justify the very small risk of slightly decreased AWD performance 3 months/year. But if guys say the AWD performance is terrible (and I don't even know what that'd be...maybe it jerks or hesitates or doesn't have good traction, etc) then I may not get it and just live with xDrive all the time.

Valid question, but remember that XDrive shines most when shit hits the fan. People keep arguing for years whether Quattro or XDrive is better. The answer is - depends entirely on the situation. Therefore I personally would not expect anyone to be able to tell a difference before and after XDelete, even if there was one. You'd need a direct side-to-side comparison to be able to categorically tell.

I am however still planning to challenge the developers to give me an answer about what XDrive I'd be getting post XDelete. This to me is worth more than users saying XDrive "feels" like before. Of course it would, even if suboptimal in certain scenarios, as there is no direct comparison.

If anyone does get an answer - please share.

Just something to consider.

Hi,

As there are a few questions, lets start with how xDelete works:

+ We flash the xDrive ECU (called VGSG or LMV) with an altered dataset, to keep the transfer case clutch open all the time (OFF) or operate differently than stock (Sport, Snow). This means, your front wheels won't be driven any more (OFF) or will get a different amount of torque (Snow, Sport).

+ xDelete can calibrate the xDrive to only transfer e certain amount of torque to the front axle (for example 100NM). If your engine does not deliver 100NM the front rear split is different, then when the engine delivers 600NM. So it is not a constant distribution between front and back (like 90:10 / rear:front), but a relative.

+ For the xDrive ON, we simply flash the most recent stock calibration back on the xDrive controller. So it is completely stock again in xDrive ON mode.

+ You loose nothing, your car is stock again, after either doing a "full stock flash" or flashing xDrive ON.

So flashing back to stock, are you stating that there is absolutely NO way a dealer or BMW NA can detect this has been done?

ie, maybe a reflash counter, et al?

Which quattro system? I think there's about 5 different ones out there now.

Just something to think about.

Correct, with normal diagnostic tools that every BMW dealer has at his disposal, xDelete cannot be detected.

It is fantastic that there is now RBT representation here to answer some arising questions! Thank you for the clarifications. Please see some questions below:

Is the VGST the only controller xDelete "touches"?

Please elaborate on that. Under what circumstances does XDelete do that? Is that a separate mode? What is the advantage of this, noting that the stock split is also not constant but dependent on a number of factors.

Quote:
+ For the xDrive ON, we simply flash the most recent stock calibration back on the xDrive controller. So it is completely stock again in xDrive ON mode.
- What is the source for the "most recent stock calibration" and when is it acquired by XDelete? Also please define "calibration", I notice you use different terminology here from the first bullet point - "altered dataset" for 2WD and "stock calibration" for XDrive... please elaborate.
Does XDelete make a backup of the stock dataset before overwriting it and if not - why not?


Quote:
+ You loose nothing, your car is stock again, after either doing a "full stock flash" or flashing xDrive ON.
Since I have never used XDelete, please educate me/us - are those 2 different options ("full stock flash" vs. "flashing xDrive ON") and if yes what is the difference between the two?

Thank you again for providing clarity.

Thanks to RBT for providing clarification. In addition to the relatively generic question I asked initially, I'm also interested in the more nuanced questions listed in the previous post.

In addition to those, I have a few additional questions:
-Do you plan to offer Sport/Snow/Custom for the F30 like you do for the E90?
-If so, why isn't it available now? Is it just a matter of time before that version is updated or some other reason?
-If not, why aren't you?

I really like the idea of something other than simply on/off so I'd be even more interested in XDelete than I already am if that functionality were available for the F30.

Thanks again for chiming in!

The F30 transfer case is considerably weaker compared to the older E-Series units. They just overheat very quickly and go to limp all the time. We do not offer that modes for F-Series, cause those units would be fried very quickly during drifting. The transfer case on F-Series is called "ATC35L" and "ATC45L. "L" stands for "Light" which pretty much describes it....

Got tired of waiting for a sale lol
Just bought it and flashed it to my f33.
Flash went well. Took it to gas station to fuel up and immediately noticed a difference in the turns. Taking a nap before work now and will test it some more on the drive to work.
