I'm not sure what you beg to differ about? We agree on the problem being in the software.

Something else I would suggest is being more deliberate and consistent with your throttle input. I don't know how any of you drive, but I've noticed this delay happens more if you jab the throttle or have a couple "false starts" before committing to pulling onto a road. Try to roll onto the throttle with a steady and firm input. This is just a theory but I think the delay is a result of the transmission not being able to decide what gear to be in based on the throttle input being received.

Agree that a smooth consistent pedal push results in a better response, but I find that when I urgently need a little boost, eg to merge into another lane, that's when I feel the 'delay'.... But again it doesn't always happen like that. Sometimes with the same light but sudden throttle press it responds instantly!

Sport Plus seems to have more initial delay/lag than Sport.

I'm still testing this (after one year!) to see whether they both still end up at roughly the same acceleration time, eg to 100kmh. But by feeling it seems like the Sport Plus (after the initial lag/delay), has more 'explosive' force compared to Sport


Anyone else find this?

This is where using the M/S mode on the shifter comes into play. I find M/S is a lot more eager to put the transmission in the right gear for the situation, and often times it will downshift immediately upon entering M/S mode. This will lower the chances of you being the wrong gear when you want to stomp on the gas.

I know this is an automatic transmission, but I encourage you treat it more like a manual in these situations. If you want good throttle response when you stomp on the gas you gotta be in the right gear; this is really the crux of the issue. I'm not at all defending the software, just showing how I work around it.

As for sport+, I never use it so can't speak to its effectiveness here. I would rather shift on my own then put up with the obnoxious tendencies of sport+ mode personally.

OP were you ever able to solve this? I have the same problem and have tried sport mode, M/S, and turning of DSC (short press) and a combo of all of the above, to no avail. I find this problem particularly bad when going from a start. Think trying to turn out onto a busy street and the car rolling forward slowly taking a couple seconds to kick in and accelerate. It’s usually always when I’m going from a stop and need to GO! It’s very frustrating and frankly dangerous.

I had that delay since I bought my x3 in March. I flashed xHP stage 3 two days ago and the delay is gone in comfort D and Sports D.

Sorry for being dumb but what does that mean to flash xhp?

Is there also a difference with the XHP with the X3 in M/S sport mode? or is the difference more perceptible in Auto transmission only?

Yea. Noticeable difference in shift speed and RPM shift range.

That was my biggest problem with the X3 when I got it as well(only 6mo ago). The xHP transmission tune has made a big difference. There is a specific stop sign/turn when I get off the highway for my exit that always causes the issue and I have noticed it much less now with the tune. With the tune, plus switching to M/S mode, when pulling up to the quick stop and go turn, its completely eliminated the hesitation.

Just be aware, xHP isn't a complete fix immediately though. I was actually a bit dissapointed when I first tuned my transmission, but it has adapted more and I've learned how to drive it a little different as well, which has improved the driving experience with it significantly.

I’m surprised that no one has mentioned a Throttle Response Unit.
I have the Pedal Commander on my 2018 X3, there are quite a few of them out there. Regardless of which unit you buy , the difference is night and day. Someone in the forum has the dahler unit which also has a valet and anti theft setting on it .
The car Accelerates completely different , depending on which setting you have it on It can actually be to to responsive.
If you want to get rid of your throttle lag , I recommend you look into these .
The difference Is crazy .

Maybe its diffrent for the 30i, but the M40i changes the throttle mapping based on which driving mode you are in.

I thought he was talking about acceleration out of the hole . The throttle response units do change your shift points as they get you to the speed faster for your transmission to shift into a higher gear .

I'm talking about acceleration out of the hole as well. When slowing to a stop, say at a stop sign, or turning lane, if I transition from the stop to start moving again too quickly, there was a significant lag before the car would actually accelerate. It felt like huge turbo lag, which we know isn't the case with a stock turbo B58, but you could see even the RPMs weren't going up like they should vs the peddle position. This would occur even in sport modes. It was a huge hesitation and would make for a very awkward take off because I would just keep pushing the gas further down until it would finally move, but it would be an over acceleration then at that point.

This wouldn't happen as bad in say Eco Pro mode though because there was already a big delay in the peddle anyways in that mode. It was less jerky, but still a slower take off, which wasn't what I was wanting.

Once I got the xHP transmission tune, it fixed a lot of that and now the only hesitation I notice in sport mode, is the actual turbo lag when I'm lower in the RPMs, which is pretty small on a stock B58.

So, I could be wrong, but I don't believe your throttle response units would change that fact much at least on the M40i.

Just a heads up too, the Pedal Commander is not going to change your shift points. You just happen to be accelerating more with less throttle input and getting to your shift points faster during partial throttle, but that's it. They aren't going to change your shift points or make you faster in any way. It's the same speeds you were going before, just requires less peddle travel to accomplish it.

TL;DR I'm not saying a Pedal Commander would not improve driving experience for some trim models, but for the M40i, I don't think it would fix the hesitation being discussed here.

Sound like you know what you’re talking about .
Not sure why you are asking questions when you already have the answers .
The throttle response units do remove that lag as it’s tricking the electronics .
Have you tried one ?

It's even more of a difference in M/S mode

30i , 40i it doesn’t matter all of your shift points change with the different modes. Sport , comfort and Eco

You may be confusing me with another post then since I haven't asked a question.

The lag being removed by the TRU tricking the electronics is simply changing the throttle positioning to give you a sportier feel. Literally exactly like Sport, Comfort, and Eco driving modes, but the Pedal Commander is just giving you more adjustability to the Throttle Position, not your shift points.

Think of it like this, if your throttle is a 1:1 situation, and you have to push the throttle down to the floor to reach 100% WOT, but when putting the Pedal Commander on it, you can reach 100% WOT with your pedal at only 50%. It's not changing your actual shift points, its just giving you wide open throttle with less pedal.

So it can feel like you are moving faster when just driving around, because you are just driving like you are flooring it harder than before. But if you are at WOT in either situation, your shift points are still going to be the same, and you aren't going to accelerate any faster with a Pedal Commander

Did you mean to quote me on that? Because I was responding to a question about xHP and how it feels.

And yes, I agree Sport, Comfort, and Eco change shift points, but that's stock and completely seperate from a Pedal Commander.

Here is the link to Pedal Commander's website for you to review. It is a Throttle Response Controller, it does not change your shift points, only where your pedal position is for the already built in programmed shift points.

No , my response was to the OP .
You’re the one that jumped on my suggestion . I have the Pedal Commander, I don’t need to read about it

Then you might not want to quote me since my reply was not to the OP either.

And I didn't "jump" on your suggestion, I was merely stating that the M40i already changes the throttle position sensitivity based on the driving modes and that it likely wouldn't fix the hesitation.

Believe what you want, but claiming the Pedal Commander changes shift points is just not true. It's only manipulating the throttle position sensor.
