CLeagones - you can do Stage 2 with the Accessport with an off the shelf map from Cobb, or you can go deeper and have a custom tuner referred to you from Cobb do a tune.

X51 Thanks !!! I was surfing Cobb maps for my .1C4S and didn't come across a Stage 2 map...Maybe they took it down from their site..

Send a PM to COBB Tuning and ask Marshall.

Is there a 100 octane tune for the 991.2 Carrera S?

Is there any chance of "bricking" the ECU in the car during the flash if something fails? In that case is there some warranty or recovery process to get the ECU back and functioning? Had a friend flash through the OBD port some years back in his BMW (not COBB) and the process bricked his ECU. Was left to replace his ECU by the dealer at outrageous cost.

Thanks for Cobb for their support, and I hope they will continue to listen to us here with the hope of adding new features such as removing the autoblip (rev match) and having the car start in the mode it was in when turned off, such as Sport or Sport+. Another unnamed tuner is looking into an update for those items so it would behoove Cobb to do the same!

Thanks Cobb for my GT2-RS killer : )

@Marshall has anyone done up graded turbo’s with Cobb yet?

Do you have anymore development planned?

Is the PDK tune far away?

It would be pretty hard, but should be fixable at home. I'm not a pro but the way the OBD flashes work, you have a base (Stock) map and that is Version A. you read that and your tuner (Cobb in this case) modifies and send you a tweaked data set of the Version A file. You load this and you are on your way. 2 years down the road if you Porsche releases Version B and you take it in and have that flashed onto you car youll be back to 'stock' but on Version B. You would need to have Cobb send you the same tune but on Version B base file else if you load your original Version A base modified tune you risk temporarily bricking the ECU. You would need a clean Version B unmodified, and then load Cobb tuned Version B.

This is the step that if there is a screw up, it bricks your ECU. Once corrupted, concern is that the ECU in the car must be physically replaced. In the case of my friend, he was in the process of loading the modified map into the car when a failure occurred. The corrupted ECU would not run the car and another ECU was required. The software tuner that sold him the software claims it was his fault, and disavowed any responsibility for the replacement of his ECU.
This is a good reason to consider using a tuner, because at least they will be responsible if a fault occurs during the upload.

So my question to Cobb is what do they do or warranty in this situation? Will Cobb replace or repair the car's ECU?

911.

That is unfortunate for your friend. I've bricked an ECU before with out physically needing to pull the ECU and repair/replace. Car was out of commission for a day. I too am curious to what Cobb has to say,

i just installed it in my driveway. In theory you could “brick” the ECU by turning the car power off or disconnecting the cord connecting the AP to the car in the middle of the tune but honestly you’d have to be an idiot to do that. Even then I wouldn’t know if it is bricked I imagine you could probably reflash although Cobb states it wouldn’t cover that scenario. I’ve had a friend who through a Cobb tune on top of another tune and def had some engine issues.

How did the tune affect your performance? How long have you had it running with the tune

DHL

Sometimes during the software flash sh*t happens. You know you bricked the ECU because the car no longer runs or starts. I have heard that earlier flashes required the owner to send the ECU into Cobb, so that is at least encouraging that may be they could recover ECU functionality at their factory, but I am wondering why Cobb is silent on this issue here on the forum.
