Update from my end (since I also mentioned subdued burbles compared to stock ZCP). I don't know if this is by design but when I am driving in a more spirited fashion (usually mountain roads) I can absolutely hear the pronounced overrun. Now I can't do an objective side-by-side with stock ZCP but I can definitely say it is there.

CarBahn Autoworks I appreciate the focus on delivering a quality product and I definitely got that feeling when we chatted in person w/ Steve himself. I'm willing to be patient until you all complete your test regimen, but I would be lying if I said I wasn't anxious for s smoothened curve.

Looking forward to the updates and let us know if you indeed did change the overrun tables. I certainly wouldn't mind a little more burble.

Thanks for your interest. Here are the answers in order:

1. Yes, we are working to create a CarBahn dealer network, which will comprise of both independent shops as well as francised BMW dealerships.

2. Our flash tunes are compatible with Dinan bolt ons such as intakes and exhausts.

3. If you purchase exhaust overrun/roar for a ZCP car, both will be more pronounced. If you wish to retain stock levels of both, you will want to select "no" for those options at purchase.

4. We can reach out to one of our trusted shops in your area to aid you, but I think everyone who has purchased the tablet can attest to its ease of use. A comprehensive instruction list is included which will walk you through from A to Z.

We want to let everyone know that it is in progress. But, we've still got a couple kinks to work out, and it will be a bit longer than we anticipated. Have full trust that we want to get the updates out and running ASAP as well, since we have several potential customers who are wanting this update to be online before making the purchase. Right now, we are pushed back approximately 2-3 weeks. I know this will disappoint some but we appreciate the patience of everyone waiting for this update. We prefer to make sure any and all updates are 100% perfect before putting them on our customer's cars, even if it means a bit of a delay.

Thanks everyone!

regarding the BMW dealer networks, will this be nationwide or only in your operating state of california, specifically northeast would be great?

Thanks!

Optimistic two week bump for updates.

any updates on the F90 M5 competition tune?

My dilemma is I know absolutely nothing about flashing it myself using a tablet and I'm based in Charlotte NC and previous question regarding Charlotte didn't point to a local tuner in area.

My interest in Dinantronics was the fact that my BMW dealer will install and they actively promote Dinan products. I know there's lots of back and forth about Dinan vs. JB3, BM3 et al. but I have my reasons for choosing Dinan.

However, given who's at the helm of Carbahn and my research on the merits of flash vs. piggyback, I'm now seriously leaning to Carbahn. I'm just not sure how to proceed being on the east coast.

Questions:

1. Are there plans to offer this through BMW dealer network, like with DinanTronics?

2. Do other Dinan products, like intake and exhaust compliment Carbahn flash tune?

3. I would be buying the option for overrun, but will I retain the same burbles / overrun that I currently have with ZCP tune?

4. If not through BMW, are there other local / reputable shops (e.g. GMP Performance, Eurowise) that could flash car assuming I got the tablet option?

Thanks for any information.

I am sure they will walk u through the install process. It is Very easy to do and they also provide detailed step by step instructions supplied with the tablet and cable. They have a great support team and have responded to all my emails promptly...

[BzsBimmer]

Yes, easy to do. Worse case, find someone close to help 😁

This is the tune I want, the warranty is what does it for me, I'm Ok if its more conservative and not as many options as the others. Just waiting to hear reports the throttle mapping is smoothed out..

[EricSMG]

I'm interested in a 'flat torque' tune that has a near stock midrange but lets horsepower continue to climb to ~7k rpm... essentially matching the 7k hp numbers of this current tune. The huge midrange hit of the current tune seems counter productive for sport driving without boost reduction by rpm.

Any plans for this?

[brad-cam]

I did a track day at Sonoma Raceway last week on this tune, Sport mode, worked well, could feel the extra torque especially. I think it could benefit from being flattened out over a broader rev range a bit, but generally happy with it. The off-idle issue is of course not really a factor on the track

Hello all,

The throttle mapping changes are applied and awaiting validation. The car is here, and just waiting for its turn on the dyno that is currently occupied by a 800bhp built S63 M5.
It's been a long time coming but it is almost ready. Our personal thanks to all our customers who have been more than patient.

RE: F90 M5 and B58 software- we have test cars here already, including a B58 with an updraded turbo, we are waiting for our tuning platform to grant us access into these ECUs before we can get a move on.

What about M2C?

[reprod]

@CarBahn Autoworks Any update?

[_robert_]

Anyone want to be the first to upload a video of the burbles in this tune?

[SYT_Shadow]

do you have anything for the M3/M4 CS or do those use the stock F8X tunes?

[CarBahn Autoworks]

Hello everyone!

Here is an update. In addition to the throttle mapping, we have also created a significant improvement in mid range power.
But that's not all, we are also finished with the torque reduction feature in lower gears for manageable power delivery.

We will start rolling out the revised Generation II files by the end of this week. That means F8X customers will start seeing updated files by the end of the week.

Check out the comparison. Yellow/Orange is Gen II, and the dotted red is the outgoing Gen I.

Thanks everyone! We can't wait!

We do have a calibration for the CS models, to be announced shortly. Power wise, it will be very similar to that of the Gen II software, graph above.

M2C efforts will be back in full force once the M3 M4 Gen II updates are out and everyone has their files!

[CYA CFA]

Ooh, that's a nice looking curve - let's do this!

[CYA CFA]

Here's a thought, and I apologize in advance if it's already been discussed elsewhere, but it only dawned on me after mention of torque reduction by gears ...

Would it be possible to leave Efficient totally stock in absolutely every respect and apply the tune exclusively to Sport and Sport+?

I might be the only one out there who would even want this, but when I'm white-knuckle balancing it in fresh snow, stuck in bumper-to bumper gridlock with two kids in the back, or watching my wife trying to parallel park I don't always find myself saying "Hey, I wish this thing was producing way more power RIGHT NOW."

Obviously the rest of the time I do ...

Just a thought.

[EricSMG]

Still question the objective here based on that slope. You're going for bragging rights/dyno/peak numbers over a true motor sports driving experience, it seems, which is somewhat of a turn off.

The power drops dramatically from the 6k peak to 7k rpm (it essentially matches stock power at 7k rpm). This will make the car very "not fun" to wind out. You've essentially created a mid-range beast... effective, sure, but where's the reward in it? These cars are really, really fast stock so why not at least offer a "driver's" tune?

Not trying to be negative, just calling it like I see it.

Is it possible to see the power curves with the torque reduction active? Perhaps the drop off is less severe in gears 1,2 and 3 and thus resolve my primary point of contention with your latest graph.

Wait, wait, wait. 3 isn’t a low gear. We’re just talking 1 and 2, right?
