I really enjoy the acceleration while in motion, but the hesitation on take off feels delayed sluggish and leaves me wanting more. What have you done to your car to improve this and how big of a difference is there?

I have 2019 540i w/ m sport package

That pic is magazine worthy (cover, article, center, you name it)

you've tried the 'kick down' launch control thing? Only other thing I can think of is high rpm, but yeah it takes a moment or two to shoot forward

[Apl530D]

Nice pic!

Engage R for Race.......

On a serious note, does anyone know if there is a gearbox remap for these yet?
I think XHP did one for F series cars.

I always just put my car in sport when I need the faster response, there is a very noticeable difference.

[sandwi54]

The only way to do it is by putting the engine in sport mode. You may code your car to always start in sport mode, which is what I did to my wife's car. That throttle response is extremely intoxicating.

The annoying part is that sport is more responsive than sport+

I use sport mode and it still it just … meh.. does anybody the Mods fix this?

You may need the M550i then. It seems you are looking for better low-end torque which only the V8 can provide.

Only flash tune will give you the responsiveness you are looking for

Deactivating the Dynamic Stability/Traction Control and using Sport mode will help.

I have a 19 540ix M sport and if I’m in sport mode and motivate the car with my right foot it’s a solid performer. If that does not float your boat likely it is time for a V8.

This is my DD and fast enough for me to enjoy but nothing is really as fast as I want it. I also like getting 22-28 mpg. (Virtually all highway and 70% sport)

It’s a $/performance trade off that has been around as long as cars have been built. I’m not tuning it either bc it will be picked up and will void the warranty.

[jsf721]

Word of caution.
With out the proper training ...

You can end up with a handful if things go bad with the babysitters off.

I did vrsf catless downpipe and bootmod3 stage 2 tune, response is great to me and really quick imo!

[540iSUP]

If what you're experiencing is what I'm experiencing, then I feel your pain.

I have Bootmod3 stage 1 ACN91, feels great and throttle is responsive, but I don't like the dead pedal feeling when I smash on the gas. Its as if there is a delay between when you depress the pedal and when the car says "oh you want power?" then it kicks in. I thought a tune would alleviate the problem, but it doesn't. I'm thinking about purchasing an xHP tune for the transmission, but I doubt that will change anything. I'm guessing the real solution would be a pedal tuner like the one from BMS, Injen, or FTP.

A tuned 540i has plenty of power for my needs, it's just that dead area between flooring it and the throttle actually opening up that I don't like. A freaking truck was able to cut me off at a Red light because he was able to take off at the light change and my car hesitated for about 1 sec before I would've blown the doors off it.

I've eliminated the hesitation on past BMW's with automatics by putting the transmission in manual mode and downshifting so that first gear is displayed as the current gear.
Until I did this, it felt like the car was starting in second gear and then decided, once full throttle was detected, that it should switch to first.
I haven't seen any car magazine articles in which they prove BMW's start in second gear.

I know you are not looking to change your car, but just so you know: I went from a 540i to a 530e and one advantage of the PHEV is the instant torque from the electric motor. The 530e is of course not as fast the 540i, but it feels MUCH more responsive and quicker off the line.

I have a Hybrid Lexus CT200h. That dinky little 1.8L takes gets off the line so much faster than my 540i. Of course, after about 1 sec I'll blow past it. But I have to agree, the instant torque of the hybrid is nice.

[540iSUP]

Well, I'm now stage 2 with a decat DP, FBO, and xHP stage 3. Much better response, now the only lag is turbo lag.

I have a 1.6lt 520 G30, can you imagine the hesitation I experience everyday?

Launch Control is the only way to overcome it; or increasing idle a bit by tuning or completely changing the torque distrubution towards lower rpms. But as long as the gas pedals are not wired directly to the throttle there will be delays. Pedal commenders or using a linear curve on tuning maps for pedal/throttle percents can solve the problem.

Pedal Tuner improved response on my 740 only slightly.

I'm looking forward to the 4 cyl motors getting mild hybrid. The instant torque of even 20hp fills the gap.

I've got an m550 and there is still a slight delay..I came from a srt Durango where there was 0 delay..
