What’s the status of stage II hardware and software?

B58 status?

Perhaps the F8X S55 forum isn't the most appropriate place to ask for B58 information.

Since carbahn mentioned the B58 tune in this thread I have followed it. I will be more than happy to discuss the tune further once they post something over in the B58 section.

Any chance to get cold start delete for off-road purpose?

I upgraded my F80 to the latest flash in April and did my first track day with it this past Saturday. I am generally very happy with it, but I was having trouble with the charge tubes coming loose from the clamps (the ones on top) under hard continuous acceleration, assuming a long high boost condition. I tightened the clamps between runs, really tight. On the last run the other side blew off - the intercooler output came loose from the elbow that connects to the intake manifold. I reconnected and tightened it really good after the track time was over. Now I'm worried that this flash drives the boost to a level that the plumbing can't take it. I have not broken or split the plastic charge tubes yet from what I can see.

Has anyone else had problems with this on the latest tune? @Carbahn, do you have a curve graph that shows the levels of boost that this tune produces vs stock? For example, by RPM, load or both ?

Thanks!

Sent you guys an email trying to figure out pricing?

Just had this installed at Carbahn in Mountain View. Power compared to stock is incredible. Only issue right now is that I don't hear any burbles at all but hope to get this resolved soon.

I just got the smooth power stage 1 tune installed on my M2C (fully matching warranty), which was installed by my Carbahn authorized BMW dealer. I opted for the "startup roar/burbles" option and it sounds absolutely sick with my MPE exhaust. A bit more burble from stock.

Only pita was the need to remove the DME and have it overnighted to Carbahn in Cali, due the DME being locked....but all was done in a few days.

The tune is manic, especially going from M2C stock power. A bit less of a jump from F80/F82 base and comp S55's.

Highly, highly recommended!

How are the burbles in sport and sport+ mode? Similar to stock? I noticed a few earlier mentions that the burbles were quieter, so wondering if that has changed now.

Also, how is daily drivability in terms of smoothness at partial throttle applications?

The burbles are the same, if not a bit louder now (and they were very loud stock, with the MPE).

Drivability is great, unchanged from stock, just with more power everywhere. Loving it so far!

Any more reviews?

Just got tuned with stage 1 from a competition M3. Nice jump in power and very streetable, even with winter tires. Overall very happy and happy to answer any questions.

QQ for the Carbahn guys: sport plus now does rev matching after the tune. Is this expected? Can I turn that behavior off?

I am always in sport plus, and rev-matching is always on. It will only disable if traction control is fully off, and I always have MDM enabled.

Yes, It can be turned off. If you return to the dealer that did the software flash we can send it over a new file

Or if you did it with a tablet we can email you a new file directly.
