On my 335i n54 with a muffler delete I literally get a gurgle everytime i let off the the throttle. I can sit the and feather the throttle and It'll just keep on gurgling haha. I love that gurgle sound.

stock e93 other than MHD and a DCI. The medium setting for 3 seconds is a pretty good balance between sporty and sleeper. It gurgles every time you let off the throttle and occasionally when you get on it harder it will pop and bang. It's a nice balance between enjoying the sound with the windows open or top down but without being obnoxious to others on the road.

Though a WOT 2nd and engine braking will definitely still get some pretty loud bangs.

has the honeymoon period ended yet?

pattern so far:

waiting for implementation -> flashed -> awesome! + lots of videos -> tweaking for the sweet spot -> some oddities felt + noise gets annoying -> undo burble option

lol

Same thing happened to me. Happens during the duration of the burble. Once the burble ends then powers returns. So now i jus keep it at 1 or 2sec

Same issue here.

Also the car was way too jerky and didn't have that crackling sound I was looking for.

I love the sound, don't get me wrong.. But i was under the impressions that there was no side effect to performance? Maybe just needs to be fine tuned a little?

The jerkiness some are experiencing is being looked into, it should be a pretty easy fix!

+1. That's the problem when everyone signs up to be a beta tester.

I highly doubt a passenger would even notice the jerkiness, but it just wasn't going to work for me....

Second, or 20th here I guess. Noticeable Jerkiness that can be dialed out with the right foot but it's definitely there. Also I put about 400 miles on the car this weekend, all kinds of roads, streets and my mpg is only down by .2 (yes I reset it) With the setting on aggressive I can even hear it burbling when I coast on the freeway above 70ish since my rpms are over 2k.



Here's some cracks on a sharp decline windy road.

Yes, which is why I'm giving feedback and asking others are experiencing the same even with different setups.

Hey Jake, would this also address the loss in momentary throttle response that I posted above also?

I don't think people are complaining (most of them anyway), but mass feedback is great and rules out isolated issues in a smaller beta audience.

Yea I don't have this. So might be worth getting a log to see what's up.

Also, Jake, if you need a log of the jerkiness from a stock 335i e92 let me know.

I see there was an update to the timing and an additional aggressiveness setting.

So, 35is would be equiv to 2.25/stock?

- Exhaust burble: added a "softer" setting + duration now goes from 0s (for pedal only control) to 5s by 0.1s increments.
so much more control

i guess the softest setting is for the jerking manual people to try?

I have DP's and BMW PE, the second most aggressive setting seems to sound exactly how my car felt lightly tapping the throttle, except about 1.5-2x more bubbles/gurgles without touching the gas pedal. Very awesome!

No negative symptoms to report here.
