BETA Firmware Update for BMW AccessPORT: 2011 335is Support and Datalogging Updates

[COBB Tuning]

A BETA firmware update for the BMW AccessPORT is now available from COBB Tuning. This release adds calibration and firmware support for the 2011 BMW 335is, expands the list of datalogging monitors from 19 to 68, and fixes the cruise control bug. This update also fixes the P2FA3 ECU code shown when an AccessPORT is installed. This latest firmware also enables the AccessPORT to read and clear historic DTC’s from the ECU.

New Vehicle Support
BETA AccessPORT support for the 2011 BMW 335is is now available for early adopters. Stage1 Calibrations for 93 and 91 octane fuels are available as well as Stage0 and valet modes. All 335is users can now install the AccessPORT simply by updating to this latest BETA firmware version. Note, this update only adds support for the 2011 335is and does NOT include any other 2011 model.

New Monitors and Features
COBB Tuning has added new monitors for datalogging and live data viewing to the AccessPORT, increasing the number of monitors from 19 to 68. This includes engine monitors like “Fuel Pressure,” “Injector Pulse Width,” individual “Cylinder Timing Correction Cyl 1-6,” and individual cylinder “Knock Voltage Cyl 1-6.” For a complete listing of current and new monitors, visit our BMW AccessPORT Data Monitor List.

The AccessPORT also has the ability to read and clear “historic” trouble codes removing annoying check engine lights from the dash. These latest updates make the AccessPORT the most convenient and easy to use tuning solution with the most comprehensive data logging and diagnostic capabilities available.

Calibration Updates
All performance calibrations have been updated to v3.00 with this update. Tuning has not been altered; this revision only represents changes to firmware logic. Updating to these calibrations for current AccessPORT users will not affect performance. The v3.00 calibrations must be used to take advantage of these latest updates.

Bug Fixes
This BETA firmware update addresses two bugs with the BMW AccessPORT. Some vehicles have experience disabled cruise control upon installation of the AccessPORT. This firmware update resolves that issue by returning cruise control functionality to affected vehicles.

This update also resolves issues with recurring DTC codes present upon AccessPORT installation on some vehicles, in particular the P2FA3 code. These new calibrations feature enhanced logic that no longer induce a DTC error condition upon installation. If you currently have DTCs present on your vehicle after installing an AccessPORT, reflash your vehicle with one of these new v3.00 calibrations.

How To Update Firmware
To update your AccessPORT to 1.6.5.0-2485 BETA firmware, simply open the AccessPORT Manager application, connect your AccessPORT to your computer via the supplied USB cable, navigate to the “Options” menu and then select “Check for BETA Firmware”. Then click on the “Updates” menu icon and follow the on-screen prompts. These new features will be installed automatically. If you do not have AccessPORT Manager, you can find the download link for your free copy on our Support Page. To complete the update, flash one of the new v3.00 calibrations to your ECU. Using older maps with this update may cause poor performance or unexpected issues.

These newest calibrations will be automatically installed to your AccessPORT during the BETA firmware update. For more detailed information on maps and revisions, please consult the Firmware Release Notes or call COBB Tuning at 1-866-922-3059.

That's great. But I don't own a 335is, as this states very specifically is all it's for.

How's the n55 1-series work coming along?

+1 N55

bring on stage 2

All of these updates apply to currently-supported vehicles not just the 335is. So you can get all the new features just by updating to the BETA firmware and using a v3.00 map.

N55 support is not part of this update and is still in development.

What does that mean?

Is it possible to get the over boost of the 335is on a 135i ???

[TunedM2C]

I think he's just saying the firmware update is available for all N54 models minus the only one left which is the 1M.

Speaking of the 1M, any updates on this Travis?

Thanks for the clarification.

Thank you guys at Cobb for the hard work and keeping those updates coming. I hope the rest of us will stop bitching for a sec and let these guys do their job.
Since July 21st there has been two updates. The guys at Cobb are doing a great job at working on all our issues, we just need to be grateful and patient.

[Lefthandblack]

Yess!! Cruise Control Works!!! Awesome Cobb, Thanks!!!

Pushed the car pretty hard last night, had check engine light come on. Turned car off then on and it was gone. COBB AP says fuel pump plausibility and cylinder 5 misfire. (just had fuel pump replaced), just did software upgrade yest afternoon. Any relation? thoughts?

Great job with the continued updates/support COBB. One step closer to stage 2 !!!

Just pushed mine very hard a few times. So far so good "crossing fingers"

With this update you can now log requested and actual fuel pressure! Log these two parameters and you can get a good idea if the pump is working or not. If you are getting the fuel pump code, the pump might be bad again, which would be really annoying. We have a local customer that had his pump replaced around 4 times, on a 100% stock car. Misfires and stuttering are not normal behaviour, naturally, and if you are increasing performance you are also increasing demand on the fueling system. Now that you have the ability to monitor fuel pressure AND injector pulse width, it gives you a good idea of how much fuel you are (or aren't) pushing.

Let us know if you have further questions or needs!

Thanks Travis! I'll try it today/tomorrow and I'll email you the results so you can diagnose for me .

Go COBB!

Can someone please answer this? I've been wondering the same thing. What's so special about the 335is that the 135i doesn't have? Why can't we get overboost function on a 135i? Is it possible to gain that function?

[Gimlet]

You don't need it. The COBB will provide a higher level of Boost than the stock overboost feature of the 335is. It's like having the overboost on all the time -

Best way to put it.

My impressions of the new 3.00 map.

Pros:
Cruise finally works

Cons:
1. I am noticing more turbo lag or or worse throttle response compared to the 2.03 map.
2. My oil temps are hotter. I am noticing that my oil temps are running 7 to 10 degrees hotter when comparing the same driving style and outside temp.
3. Slower. I do not know why but my butt dyno says that I am slower than the 2.03 map.

Now before anyone jumps on me to let me know that this is a beta map. I realize this and I am only posting this to give Cobb the feedback.

I have had Cobb since Jan and I cannot be more pleased. I am sure that they will work these kinks out and it will be better than ever. Ready to Stage II.

Can I change back to the 2.03 map with the 3.00 firmware? Someone from Cobb on the 3formum said that you can but the first post in thread indicates that you cannot without some issues.
