So far i've only tried Aggressive Linear and Aggressive alternate throttle V2 map on my 6MT.

Aggressive Linear feels 100x better than the Alternate throttle V2 map. Such a huge difference driving the car back to back between the two maps. V2 feels bone stock unless you have the throttle more than 50% where as Linear you feel the HP gain right off the bat. Comparing V203 to Aggressive Linear is so noticeable it was like going from the Jb3 to procede. I felt the improvement driving out of my driveway going down the block.

going to try the aggressive stock throttle map to see how it compares next.

So far no weird issues with either maps. Good job COBB!

The only weird issue that I have noticed is under abrupt acceleraton at around 2k-2,500 RPM's in 6th gear (AT). I tried it a couple of times and the car shook (misfired) a bit but no codes or lights. Any ideas? I am thinking spark plugs.

[QUOTE=COBB Tuning;10422264]

COBB Tuning is proud to announce new calibrations for BMW 135i, 335i and 535i turbocharged performance vehicles. In response to customer feedback, all BMW AccessPORT calibrations are offered with increasing levels of performance. Maps are now available in Drive, Sport and Aggressive configurations. This will simplify AccessPORT map selection and allow drivers to easily tailor their AccessPORT calibration to their specific driving style and performance needs. In addition, expanded throttle mapping options are available and each map includes improvements to power delivery. The latest firmware adds support for the latest ROMs discovered in the field.

If you have more than 20K on your plugs i would certainly change them out to see if it resolves it. They are time to go anyways.

I'll keep an eye out to see if my car does the same thing. I didn't use 6th gear all weekend lol

I'm at 39k miles on a July built 07 so I doubt that they have been changed. I feel like gunning it at such low RPM's isn't the best of ideas and it's not like I went from 10% to WOT either but at the same time I don't think this should happen.

OH MY!!!!

The linear v301 map is pure buttery smoothness! (6MT)
Some ppl may not like it since the boost doesnt really kick in until you get deep into the pedal. But the power onset is so smooth and progressive.

Anything beside the Standard throttle, feels weak to me lol

+1 I bought the 335 because I liked how it felt. I can see why someone would want the linear for auto crossing and track days. 99% of my drive time is not on the track.

Same thing happens when you exit out of a tight corner fast on the street. Proper throttle and boost management is requirement for both. It's just that on the track it matters more.

You know what, the more I am driving on linear throttle mapping, the more I am growing to appreciate it. I enjoyed that tip-in response on Procede and Cobb standard maps, but I noticed it is far easier to launch the car from a dig now than it was previously on standard/piggy throttle mapping. I can launch 1st gear on my auto (tough task) out the hole with almost no wheel spin on street tires. Keep in mind I have a non-xi.

Same thing. I have plugs on the way and a new VANOS solenoid. Hopefully this will correct the misfiring.

Only reason I ever come to these forums lately is to check on Stage 2 release..

I think not having Stage 2 on my car has lowered my enthusiasm towards my car, which has at the same time made me come less and less to this site

Stage 2 please!

ACN91 is still 91 octane, so the octane requirements would be met.

IIRC, in my Subaru days with the Accessport, you were supposed to try the standard 91 map first and if you had problems, downgrade to the ACN91 map. What I'm wondering is if this is still the case or is the standard 91 map known to be too aggressive for ACN91.

I've bailed on Aggressive Linear and gone to Sport standard mapping.
Too ho hum for my liking. Enjoyed being on the highway and while in 6th gear giving gas and going from 80 to 100 without a shift needed. All boost. A little more choppy on the front end, but enjoy the boost coming on more quickly I think.

On v203 I was using the alternate throttle v2 since I liked having the power, but only when I provided the lead foot. It felt smoother than stock in normal driving as well. I preferred this over the BMW stock map as well as the v203 standard map. FYI I was using the ACN91 maps due to the gas here in socal.

When I saw the map notes for v301 that the linear map was an upgrade of the v1/v2 series, I was excited to try it (Drive series of course).

I am not as thrilled as some others on here. Is it just me or do I sense some funkyness with the Linear map (and not just on 6th gear)? I find it hard to stay at a constant speed when cruising (any pressure on the pedal seems to increase speed instead of just hold it) and the pedal drive to power delivery is not as predictable (peeled out when I wasn't expecting to!)

I then tried the v301 standard Drive map and liked it much better than the linear map. I was hesitating to try the v2 again since the linear was supposed to be an upgrade of sorts, but maybe I'll give that a try...

Anyone else have a similar experience/feel with the new linear map? Esp those who were using and liked v1/v2 on v2xx?

[tomob63]

Snow King, I agree with your opinion. Go back and try the stock map for Drive and Sport. Have fun with these. Cobb is doing a nice job in at least giving us choices. Our feet, our perceptions and our cars all seem to handle these maps a bit differently, and that's OK. What other tune can you get into your car at lunch hour and in 2 minutes flip to a different map (non piggy back )
Peace.

I don't understand.
You preferred 2.01 v2, but now hesitating to use it on 3.01 because others like the linear map?
Just try the v2 on 3.01!

That was your favorite map before, and will mostly likely remain that way on the latest firmware.

Unfortunately, I think this is probably the best advice. The other issue is the gas in the ACN areas is quite variable, and may tend to be <91, so it's definitely YMMV.

Call Cobb. They are extremely helpful.

Please send us a PM or call us at 1-866-922-3059. You can also follow these directions for obtaining ROM support for your car. What year make and model is your car?

I just tried to install my AccessPORT and it is telling me that my vehicle is an "Unsupported ROM Version" and won't let me install, what should I do?

You have encountered an ECU that we have not yet added support for. However, the AccessPORT is able to download your vehicle's ROM which you can email to us and we can then add support. To download your ROM, follow the instructions found here: http://cobbtuning.com/info/?id=5848. Next use AccesPORT Manager to save this file to your computer. Then email the file to rom@cobbtuning.com along with your Name, Email address, Vehicle Year Make and Model and transmission type. Once we have the ROM adding support should only take a few days and we will email you with instructions for adding support to your AccessPORT.
