BMW seems to have endless variety of tunes for S58 in its model line up
Here is the low to high gradation. The higher you go – the more powerful the car feels and the lower torque feels available on the scale. all OEM - all with warranty.

M2 manual
M2 Auto (different tune vs manual?)
X3M pre LCI non comp
M4 – manual
X3M pre LCI Competition
X3M LCI non comp
M4 Competition RWD
M4 Competition AWD
X3M Competition LCI (that one is weird, torque kicks in at 1500 RPM – I own one)

2025 M4 Competition AWD 525 HP (april 2024)
M3CS
M4csl

X3M board has endless discussions on that on pre LCI cars

Alpina B3 Touring also uses the S58

Good one. Alpina usually tunes there cars to have more torque down low. Than might be the torquest one yet. (I have not driven one)

Kind of makes sense the tune for X3M would provide more torque down low.

BMW could really capitalize on this by providing an a la cart tune menu to customers, pick your torque/power profile, for a price. It's all in software.

They want to sell these subscription services, well I, for one, would happily pay for a la carte tuning. No reason it couldn't be a push of a button in the performance menu.

As nice as that would be it seems like they would never do it because it would step on the toes of other models. Unless they priced it so absurd that it would close the gap to the next model up.

This. The whole point of tuning them differently is to give the cars different characteristics which matches their price points. It would defeat the purpose if they allowed the customer to do it.

That being said, I'll be interested in aftermarket tuning solutions once I get bored of the factory output. I'd also look into a flex fuel tune with an E85 station a few miles from my house. I'm just wondering how much the manual transmission can take as it looks like an E85 tune on the X4M nets nearly 700whp.

I noticed that none of the press cars seemed to have done the break-in procedure, based on their mileage. It's highly likely the car will be more powerful than perceived by the initial press.

They had the car for mere hours in one day. I highly doubt that's good for more than 10hp

It's the tune and it makes absolute sense. When you have all these different cars sharing the same motor across different price and performance ranges, BMW is going to tune the motor to fit their business plan.

If the M2 felt as torquey and powerful as the M3/M4 out of the box then they might have trouble selling the M3/M4

As far as the tune goes, it's a great problem to have. The aftermarket will solve it and then some.

[Carefree]

I’m one if the oldest contributors here, perhaps the oldest, and have a different (minority it appears) take. I’ve owned quite a few cars including 4 classics (1965-1970 muscle cars) and currently a pair of 240i. I preferred to not modify them IOW bone factory stock. Am I missing something with my upcoming G87?

[JG13]

I guess that depends on how satisfied you are with the power delivery of the tune out of the box. Nothing wrong with not wanting to modify anything. But one of the nice things about these motors is their 'tunability'. There is a ton of power up for grabs if you want it.

Personally I would love to be able to switch between different maps for different moods and situations

there are other components and design aspects that need to be considered when tuning an engine as an OEM. some of those different models may even have internal engine differences that are not made public.

Drivetrain calibrations are not developed in a vacuum for each component. it won't be as easy as loading an X3M tune into your G87 and expecting to preserve your warranty coverage, or for the car to run properly for that matter. Lots of factors at play and i wouldn't expect BMW to offer you an off she shelf M4 Comp level tune you can load into your G87 in the near future.

You are correct
According to tech documents there is a
difference in the engine identification. M3 Base S58B30O0 and M3 Competition S58B30T0. The letters O (Base) and T (Competition) mark the respective performance class. From the past, it can be said that there were also hardware differences between the performance class. Unfortunately, I don't know how this is in this case. The S58 in competition, CS and CSL have the same identifier (T). Only the base model is an O.

The G87 has the S58 O engine with specific tune. I believe this engine is for manual transmission equipped power level only as you stated. Shared by only the M2 and M3 base models .

Edit: disregard everything I just said

G87 has an S58T, see here.

P.S. Ignore the title of that thread. I never said it was for the Comp model, mods changed it.

Nice!I heard that interview from the BMW engineers where they say it's one or the other and obviously misremembered. Sorry for the mistake - my brain is fallible.

Protool enables user to go in and change the preset tune, because they are all preloaded, just have to select the one / ones you want.

A longtime member "F87source"posted a series of comprehensive how-to guides on the G42 forum about a month ago, but I've never used Protool myself.

Here's his tutorial How to code the Steering (EPS) on an E, F, G series BMW

its far cheaper for bmw to change the tune on all these S58s than to actually change internal components.

as far as i know there is no difference in S55 motors for the F8x M cars. Only outlier would be the GTS which was that water injection port in the intake.

Interesting. I've been coding my cars to enable features, adjust parameters to basic functions with great success in the past. I feel fairly confident in doing these things myself. Does anybody have any experience in changing these preset engine tunes? I have yet to find information on that in the forums. In theory, it all operates under coding, so it wouldn't trigger the BMW system to flag the car right? I've never had any issues with my coding interfering with warranty/service work before.
