Thoughts on Cobb or GIAC?

Ok, it's been a few more weeks and here are my thoughts.
1: My car hasn't blown up. Always a good thing and a worry for modifying an expensive item.
2: Lay into the throttle, and the car takes off like a scalded cat. There's a slightly longer than normal hesitation as the car figures out just how to satisfy your need for speed, though. The factory programming felt better at noticing an unexpected need to accelerate (say, switching lanes in a tight traffic situation).
3: The engine and transmission are kinda schizophrenic. The engine wants to burn gas and make power. The transmission wants to stay in a high gear and be fuel efficient. The normal factory tune strikes a better balance between these two. It really should kick down a gear or two rather than just trying to power through being on the downside of the torque curve. Mostly noticeable when you're only pushing <70% throttle or so. Probably related to what I noted above.
4: Gas mileage. Yeah lost a little, but that wasn't unexpected. Mashing the gas is so much fun I don't care. It's not that bad when I get a chance to cruise at highway speeds, but that's rare for my commutes.
I'm not unhappy with the changes; they're all things I can adapt to. A little tweaking on the PDK side of things would be welcome, though.

1. It can get a little jumpy off a full stop even with just a light tap of the pedal
2. In cases where there is a quick change in throttle application (e.g. from cruising to quick acceleration), it is very jerky, in fact almost feels the car sputters as it is trying to figure out what just hit it.
3. And somewhat related to that and per your pt. 3 above the engine and tranny do not seem to be in sync and operating in harmony. This is my biggest gripe by far.
Cobb has released updates for the 911 PDK, when you call them they consider the Macan tranny a reworked Audi DCT and stated likely software revisions are not in the works. Don't get me wrong, best tranny on a cross-over, but making it work in closer harmony (and a tad faster) with the engine + eliminating the low end jurk upon trottle application would make the offering 10 out of 10. As of now, it's an 7.5 IMO

Thanks for the review, Chris. Cobb would do well to address these issues. I'd rather have less power and a smoother experience than the opposite. Won't be spending my money on a Cobb, at least until they perfect the software.

Big plus for Cobb is that it's nearly fully reversible.

i'm thinking of getting cobb for S and reading this thread make me double check.
my main concern is, can you set cobb to be in stock map in normal mode, and map 6 or 7 on sport and sport +
I basically want slow normal driving characteristics under non-sport mode and kick in sport mode when i really want to hear the engine.

Hey guys,
Thanks for the feedback. We always appreciate hearing how our product does in real-world applications. If you update your Accessport to BETA firmware via Accessport Manager (just head over to the "OPTIONS" tab and click on the box for BETA updates) you will have access to the V203 maps. We have relieved some of the boost and throttling at low RPM to get rid of the "jerkiness" that same drivers are experiencing. Go ahead and download BETA and reflash your car if you'd like to give it a try!

Any news on updating the PDK software? I know you offer that on the 911 and Cayman platforms. Last time I spoke to one of your reps he made the claim the tranny in the Macan is essentially a re-branded Audi DSG and not a 'true PDK' (in fact he made reference that the Macan does not have the "PDK" insignia on the gear lever as other Porsche with PDKs do for that very reason...) Would be terrific if you incorporate in your offerings. Staying hopeful and tuned to such updates.

Charles,
I updated my Accessport to the latest version (v1.7.3.0-15237) but I'm not finding the v203 maps anywhere just the v202 . Both boxes for beta firmware and beta Accessport Manager updates are checked. I can't find them on the cobbtuning.com website either. Where should I be looking for the new map files?
Thanks.

You will need to update only the Accessport firmware to BETA, not Accessport Manager to BETA. Feel free to shoot me a PM if you can't seem to get the map, and I can send it over manually.
There will be new maps released later on when Stage 2 and Stage 3 get finalized as well, so we'll have everything out as a new bundle. I don't have any details or dates as to what this will look like, but it is something coming.
In regards to PDK tuning the Macans, that may be something we explore at a later date when we've done some further R&D with the VAG DSG cars like on the GTI and Golf R.

We are running the COBB AP on our shop Macan S and the results are amazing. The power delivery is smooth and very linear. This is a must have for all Macan owners.

I installed both Sport + and the Cobb Accessport on my 2018 Macan S last week. The car has less than 500 total miles on it. From a dead stop in Sport + after a little hick up it took off like a scalded cat at full throttle. In normal default mode the car runs much more smoothly than without the Cobb. The additional torque allows the car to run easier when the transmission ups itself into top gear at 35 MPH as it doesn't feel as starved. So my opinion is the Cobb purchase is well worth the expense plus the pain of uninstalling it before trips to the dealer.
