CS Owners - Whats your tune?

[eRiggs5]

Going from my base 2016 M3 with VF tune to now a 2018 CS, the car drives soooo much better. I want to tune but have hesitancy due to how nice the car drives. I would like to get more power out of the car but...

Those of you with a CS, what tune are you running and why?

Thanks everyone!

Don't mean to be a wet blanket but you answered your own question. The car is perfectly tuned from the factory don't touch it. It's the F80 platform perfected and it's unfortunate that production numbers are so low that few on this forum will ever experience it and know that. They will persist in believing it's a minor massaging of the Comp. the CS is the reason you never need to look at a G80 imo. Had mine at the track yesterday and it was magnificent not lacking for power whatsoever. Hanging with GT cars. So here comes the cliché: never mind more power….improve the guy behind the wheel (yes I know you're already amazing and just need more power).

No tune for me! I installed the lowering springs and an M4 GTS exhaust and love it! Those are the only two parts needed and should of came with the CS!

Thanks my man. You helped me answer my question. No wet blanket needed.

Yep. I have KW HAS and MPE so I feel ya.

No tune for my CS and i road course the car as much as possible. I even did the crank hub for preventative mantainace. The power band is perfect in the CS variants. If anything do the secondary cats; they restrict the power are fair amount. I had VF on the 16F80. Not interested in doing that again.

[maddmatth]

Do you really need the extra power? Sounds like you're enjoying the car more despite the lower power, maybe you're starting to see HP isn't the only thing that matters

Personally if I ever 'tune' my base M4, it'll just be flashing the CS tune.

[ABenLauda]

None. Bone stock. I've a long way to go in terms of driver mod/development before I need more hp/tq.

Does anyone know if they improved the crank hub over the years? You'd think by the CS released they'd have corrected it.

[CanAutM3]

I will echoe what others have said, the M4cs is a bloody good car as it stands. I only did MP-HAS with camber plates on mine. It had sufficient power stock to keep me satisfied.

[spool twice]

Yep, stock level powers for me too. The powerband, especially the mid-range TQ, is enough to keep things fun without overwhelming the rear end grip.

And I came from a car that was quicker in the straightline.

This car traps 121-122mph in some tests, plenty for me.

[SYT_Shadow]

No tune on mine.

I did see a tune on a CS from ESS where they kept the torque alone until like 5k rpm, then raised power from 5 to 7k. Basically looks like a GTS power curve.

I'm not going to tune, but if I were, for sure it would be that tune

[nickl630]

BM3 stage 1, see results in sig. Added a decent amount of power.

[11LMBiSTT]

No tune on my M3 CS, gotta keep it pure. It wouldn't feel right tuning a car/ecu that is so dialed in - with a great power band. Virgin, ftmfw bb!

I did add... M Performance HAS with Ground Control Camber Plates along with a good alignment, Single Midpipe, and a Remus Muffler. I have a set of RK Carbon Front Mount Intakes and ARM Resonated DPs but not sure I want to install those, at least not yet.

Also, added a set of lightweight wheels, 19" BBS FI-R
with stickier tires R888R, to help finish off my build.

Only thing the F8x CS really needs is a good set of pads or a BBK/2NH. I opted for 2NH to keep things OEM with GK Pads and Spiegler lines.

BMW OG on mine as well and it'll stay this way for as long as I own it esp since it's more than just engine power M fettled with.

How are you liking your aftermarket exhaust setup? I'm waiting on my Remus/AA-single to get shipped. Had the same combo on my ZCP and enjoyed it. I'm hoping it's boomier with the reduced sound deadening in the F82 CS + no fake speaker noise.

How am I liking it?... 2 words - In Love!

Hard to top the sound produced from the Single MP/Remus combo. It sings wonderfully. I don't even have a desire to add DPs, at least yet, because it sounds so damn good. + it keeps the sound character of the s55 engine, with minimal to no rasp unless your engine and pipes aren't warmed up. When in efficient with valves closed it's perfectly silent and with valves open in sport/sport+ it's just the perfect sound - low and deep, gurgling beast with natural pops from the factory CS tune. Also, when you're on the throttle in gears 1-3 and let off at 4-5k it produces a very nice s55 fart. Lol. The Single MP/Remus makes the s55 fart actually sound good.

If you ever want to hear mine and are in OC, lmk.

[Ex_Stig]

BM3 Stage 1 and GTS tune on the transmission.

I drove it stock for about a year and then did the tune. Now, I can't see any reason to go back to stock.

[kaiv]

I'm fascinated reading the comments from the CS owners saying the tune is perfect and to leave it alone. I feel exactly the same... except I just have plebian ZCP. It's so good I don't want to touch it; yet you CS guys have more power, more torque and who knows what other subtle tweaks and refinements. Having never driven a CS, I guess ignorance is bliss as far as I'm concerned. Been there done that multiple times with big name tuners on other platforms and it's never been worthwhile in my experience. Enjoy your stock tunes!

Can you clarify what you mean about improvements to the brakes without the acronyms and lingo? In other words in layman's terms. Also more detail about camber plates and their purpose etc. Thanks.

Camber plates allow for adjustable front camber (the angle at which the tire is aligned perpendicular to the ground, or something like that). Factory cars do not have adjustable camber.

The benefit of having camber plates is that you can setup the car with additional negative camber. For track days, negative camber will increase cornering traction and also allow more even wear on the front tires.

I agree with the midpipe and Remus. I currently have MPE and the rasp gets old. I believe the Remus is stainless which helps tremendously with sound vs the titanium of the MPE. I would love to hear the Remus in person.

I feel like the stock brakes have room for improvement. A good street/track pad and a good brake fluid can remedy those issues. But, I wanted to remedy those issues while also upgrading the aesthetic appeal of 6/4pot calipers, so I decided to go with the 2NH brakes from the M2 Competition. 2NH is the option/build code for the brakes and BBK means Big Brake Kit. 2NH Brakes are essentially the same as the CCB (Carbon Ceramic Brakes) calipers and rotors 400/380mm but not carbon ceramic, they're steel/iron. So, they're cheaper to maintain and beat on and they look great, albeit a minor increase in unsprung weight... which the BBS FI-R wheels make up for.

Camber plates allow adjustability in setting the camber angle of the wheels/tires. Which effects handling and tire wear. You don't have much camber adjustment stock.

If you want to retain your edc, M Performance HAS and Ground Control Camber Plates are the way to go. If you dont have a CS get your edc coded to the CS software.
