Burble settings stock hardware?

[E92TiAg335i]

Hey guys.

I did BM3 stage 0 CS tune to my base M4. Met up with some of my friends yesterday that have the m3cs and m4cs, respectively.

I noticed their cars burble significantly more than mine?

What can i adjust to (safely) make the car sound better on the CS map until i get downpipes?

PS- yes, i am 12

I was 12 last year...no probs man.

You could increase the aggression a notch each for Sport and Sport+.

It could also be how the CS exhaust is physically a little different from Base or ZCP.

I suggest you try the freebie GTS tune (not the AGG) and see how those burbles compare to your buddies. It's a safe stock Stage.

For what it’s worth, this is what PTF told me about the aggression slider: With stock downpipes we do no recommend going past 5.6 on the aggression slider.

Is that for stock downpipes? Or just in general?

Yes, correct 5.6 should be the maximum setting for burbles on stock downpipes according to PTF. With aftermarket catless downpipes, you can put the slider on maximum for burbles.

Thanks for that!

What about the other settings for stock downpipe: max rpm, min rpm, and duration?

No problem! Maybe someone else can chime in for those settings since PTF had never mentioned anything to me for those options. I had left the min and max RPM default and duration to 1.5 seconds since I didn't want to be obnoxious with the burbles. Feel free to mess around with those settings until you get your desired outcome.

FWIW this is their follow up to my question about the 5.6 aggression: We don't recommend running burbles without downpipe, but if you do, the recommended setting would be the least likely to cause damage to your cat. worst case scenario over an extended period of time would be your cat would need to be replaced.

The stock ZCP cars burble and everything from before so I don’t see the issue as long as you don’t want flames shooting out of it

run no more tan PTF suggest...... I run stg 1 93 and use their ots std burble. Remember the factory GTS car burbled so like Jimmy mentioned you can use that and it will give you a small bump in power

I just have the CS flash and it burbles a bit, just quiet compared to my old n55 335 that didn't burble...

I think i just need downpipes! Lol

GTS flash is free in Bootmod3. Just look in OTS maps and download.

I'm currently on CS flash. Is it that different? I don't need any supporting hardware at all with the GTS flash?

[TopJimmy]

Just a big smile...
No other mods needed for GTS.

Hmmm. How similiar is it stage 1?

My car has 40k miles and not sure if plugs need to be changed or not, so that's why i didn't flash that on my car. CS tune is not agressive at all.

CS and GTS flash are similar. Both stage 0 tune.

I would go straight to stage 1. You can flash stage 1 completely stock. It is a whole different animal.

Have you try turning up the burbles settings? If you have a midpipe the burbles should be pretty loud as is.

That was the OP's origional concern...can he run more burbles and is it safe with stock hardware

Stage1 is a little more power than GTS and it comes on a little earlier. I ran a BPMsport Stage1 for a year without any issues, then did my hub+CBC (never spun, prevention) and Stage2.

Stock plug interval is every 30K. Just call the dealer and check the service record. Prolly done at 30 and now not needed till 60K. Only need those "colder" plugs to run alcohol or very high boost gasoline.

How is stage 1 or the GTS map compared to the CS map?

CS map has the power come in much more timid (despite being a TICK more powerful up top) compared to the stock map.

To be honest, the stock map feels faster around the city.

GTS is a notch up from stock across the same basic power curve but the Stage 1 or 2 tune comes on quicker and stays stronger. Stage 2 has higher peaks than 1 but the same low-mid feeling. Nice thing about BM3 is the torque% reduction by gear, so you can tune-down to make a safety margin, or retain grip.

Awesome! How does GTS feel compared to CS?
