next time just dont clear them.

If your AccessPORT is currently stuck in Updating mode, please connect to AP Manager, click on the Updates tab, and press Ctrl+Shift+F11. This will allow you to exit updating mode. Then, delete your ROM, check the "Force update" box, and do the update again.

If you can, please get a list of those codes to us via PM and we can investigate this issue further. Is your car showing those codes now after the reflash? Did you reset the ECU and did those codes also reset? Please let us know if you continue to have issues.

This happen to me with the sport setting alternate V2... gave me 2 codes, cheque engine and no more power... re-flash and the code were gone... didn't have the time to cheque the codes... I will note them if it happen's again.

Quoting again for emphasis! Would love to get more information on the differences between 203 & 301 if at all possible!

The way it is described makes it sound like more boost. Drive < Sport < Aggressive. Maybe they are gearing their tunes more toward people who are a bit worried about the long term effects that "too much" boost will have on their cars. That's just my guess.

These calibrations are designed for ultimate performance and it is highly recommended that 93 or greater octane is used.

That doesn't mean you MUST use 93 octane or higher, does it? So can you still pick this setting even if you run 91 octane, and get almost all the benefits from it? Or it'll basically end up running like the Sport one then?

Based on the release notes, are you counting the 4 calibrations basically as stock (stg0), linear, non-linear (for lack of a better word) and valet?

As an aside, where do I get a description of how valet works / does? Cobb says valet will "limit engine revs and boost". Any specifics like what RPM's and PSI of boost?

I have pretty limited knowledge of all the aspects of tuning but, from my limited knowledge, it's not advised to run the 93 (aggressive) map on anything less then 93 gas. The problem is how consistently the fuel will burn, the higher the octane, the more consistent burn you get. When you get more aggressive the chance of knocking becomes higher becomes - a lower octane gas coupled with the timing and boost needed for the aggressive tune is not good for the engine (I am pretty sure the engine will protect itself but that's not a great way to go about things).

You can also run a meth kit to raise the octane (as well as the cooling effect) but, other than that, I only know of using octane boosters to help you (again, my knowledge is limited).

I hope these newest maps aren't just meant to placate those of us waiting for stage 2.

The alternate throttle maps offer varying amounts of engine power for throttle input. It is important to note that the pedal input does not specifically change the throttle plate on these cars. Instead, BMW has implemented logic to make the pedal input request a percentage of torque. The stock mapping has varying power output per pedal input depending on what part of the RPM band you are in.

We have now fully developed the throttle mapping in the BMW to improve over our initial v1 and v2 throttle mapping offerings. They are still available for download, but we are very proud of the new new Linear Throttle map. This map has truly linear and predictable power that is consistent across the entire RPM range.

The new v301 mapping addresses the limp code issues in the v300 maps. Otherwise, power output running the v300 93 octane map or the new v301 Aggressive map are the same.

From the v203 mapping, there were some revisions to improve partial throttle and cold start performance.

The new naming scheme offers users the ability to increase performance a little bit or to increase performance a bunch to satisfy the needs of different kinds of owners. Daily and Sport maps will improve performance over stock while not pushing the car all the way the edge of performance. With the Aggressive map, 93+ octane fuel is highly recommended and your vehicle will need to be in perfect mechanical condition (new plugs, etc.), but will make the car run like

I'd highly recommend uploading your stock rom on a storage site like dropbox.

If so, please explain then, how the AP can be used to uninstall/ un-marry the device unless you copy the rom file back from PC to the AP?

Also, to clarify this...the ROM listed on the Manage tab of AP Manager is a duplicate of the ROM that is saved and stored in the background of the AP software for the un-install process. Deleting the ROM from the Manage tab just frees up extra space on your AccessPORT to install all of our new maps!

Driving home tonight was a pleasure despite the rain and traffic. 3.01 aggressive linear is the bombdiggity higgity. Super smooth, predictable, controllable, and all the power. Excellent job guys.

[Zeus78]

To Cobb: AWESOME JOB!

It shows you are listening and the new maps are excellent. Although I have not gone through all (just Drive Linear and Sport Linear) the delivery of the power is SOO MUCH BETTER! I was enjoying so much the Sport Linear I did not even feel to change to something else. I mean for city I cannot see how it can get any better than this. No code issues, no cutoffs in power,no problems whatsoever... Just pure power delivery in a fantastic way that just makes your eyes tear up!

Thanks for the great service.

BTW: The New Naming standards are also very good. Much better than the old ones. If you attach some HP/Torque with them as well as some description on the various 3.01 throttle response V1 vs V2 it would be icing on the cake!

[uwotm8]

Am I one of the oddballs that likes the ferocity of boost coming on hard? I gave the linear map a try and it doesn't feel as fun on the butt dyno because of how smooth it is. With that said, it is definitely SMOOTH so if that's what you're looking for, Cobb did a great job with this one. Coming from a couple of subies and a gti, I'm used to the feeling of a large torque spike rather than the smoother progression. I'm going to give the other throttle maps a try.

Can someone chime in and tell me what the difference is between v1 and v2 throttle mapping?

[Zeus78]

I am pretty sure it is not an issue but I will ask anyway: Would running Drive or Sport maps on 94 Octane be an issue?

Also can Valet mode be used for giving the car to the kids? (If no Cobb can you make a "Kids" map next time turning the 135 into a Euro 116 or 118? ) :-)

Thanks.

v1 is for automatic transmissions, v2 is for manuals.

Does anyone know what is the difference between the stock throttle and linear throttle maps?

The stock throttle has a more aggressive, non linear throttle mapping, meaning you don't have to push the pedal all the way down to get full boost/full throttle.

Great! thanks, I will give it a shot. Sport Linear with DTC off is great, depends on the mood... its almost like having multiple cars to play with!

Hey I just realized I have a COBB dealer near me in Plano, Tx. Makes want to try their tune. Has anyone here made a comparison between Vishnu vs COBB?

[vasillalov]

So I updated my AP with the latest stable firmware and the 3.01 maps. I installed Sport map stock throttle response. I drove the car around town a bit, nothing serious. I must say that my car has been completely transformed! The power delivery is smooth, and from the looks of it, the throttle closures are all gone. I'll do some more testing over the weekend!

One quirky thing that I noticed: my car completely RANDOMLY decides to turn on the blower fan on the first position! At first I thought I was accidentally pushing the button with one of my rings, but then I realized that's not the case!

It happens randomly. Sometimes it won't happen for a few minutes, sometimes I have to turn the fan off 5 times in a minute!

Anyone else seeing this as well?
