I have 93 octane, at least that's what the pumps always indicate. I plan on starting with the sport mapping and may try the aggressive stage 1 once everything checks out.

Thoughts?

p.s. Does everything cobb related really need to be in a single thread? I wouldn't want to break a tradition, but this is ooooonnnnnneeee looooong thread.

I wouldn't worry about the beta version too much, if the map acts strange then just go back to 3.01. As far as how long they stay in beta...I'm not really sure; maybe a few weeks.

COBB's beta maps are usually very polished.

It's just beta so that people know they haven't been tested on a wide base of cars yet. Once people have tried them out and reported back that they have no issues then they will make them non-beta.

Just got back from testing v400 and bad news i have a 2009 335xi ijeos ecu and was running stage 1 aggressive linear throttle. i was on my way home getting on the highway(on ramp) i gave it some gas and ass i hit about 75(merging to a 65 in case the haters are around)and the car goes dead. Im not talking limp mode im talking DEAD lights on everything functioning just engine wont hold idle and when im stopped its revving the engine about 400-700 rpm (over idle). eventually turn off the car turn it back on and drive to the first exit. about 1/4 mile before the exit same thing happens again i pull over restart the car and drive extremely slowly and carefully home. anyway i just checked the code and it reads P2D59-DME INTERNAL ERROR MONITORING ACTUAL TORQUE. if u can chime in cobb or anyone else who knows whats going on id appreciate the help. Thanks in advance

Did you try reflashing?

where you at a low rpm when you gave it some gas? i had the same errors from the last beta maps. iirc rob said because the torque limiter cutting power because of gunning it on low rpms but i guess that fixed it after the official release.

yea i just did ill check again tomorrow 2 times stuck on the side of the highways is enough for one night.

and i was just cruising so most likely low rpm it came out of nowhere and happend twice so it couldnt have been me gunning it cause after the first time the throttle cut i was being very cautious wish i logged but i was going to the store and didnt have it plugged in.

adidasoccer,

I apologize for the issues your having. I would recommend re-flashing back to a v301 map until I can get some more info to you. It will be first thing tomorrow.

Thanks,
Jason

adidasoccer,

Can you PM me your email, I have a few questions to help get this figured out and will have another beta map for you.

Thanks,
Jason

Well, to be honest, I've seen weird ass issues with their v2.x firmware. The climate control fan would randomly turn on at its lowest setting, sometimes 4-5 times a minute. It was literally a game between me turning it of and it turning itself back on. This did not go away (even after multiple reflashes) till v3.00 firmware was released.

PM Sent if u need anything from me let me know

Ok now, I accidentally flashed to the Stage 1+ FMIC 4.0 'Drive' instead of 'Aggressive'..... Should I wait before I switch or this is just an isolated incident?

For the early 4.0 Beta testers, did you have this problem?

Are there any benefits of putting this on top of the latest BMW standard software rather than an existing tune?

Sorry if this has been covered!!

Apparently it is possible to directly flash over another remap. People have already done that with a GIAC remap IIRC. However, note that your Evolve remap will not be stored by the AP as it is encrypted and the AP cannot read it; it will therefor replace it with a generic map.

I would recommend reflashing to stock at a BMW dealership in order to avoid having problems with diagnosing if something does not work as it should - it would then be difficult to know whether this was caused by the generic map used or by the COBB tune.

Stg1 ST Aggressive I8A0S BETA v400, works fine so far..
Definitely smoother than v301.
As for the boost i can´t say. Because it´s raing, i couldn´t really test it..
I will mount ETS FMIC this weekend, and try the 1+..
VRSF DPs + DCI next weekend..

sounds like a good plan

Tried the 4.00 stage 1 aggressive stock throttle map last night and this morning. Big improvement from 3.01 I think - much more refined. No codes/torque issues for me so far, even from a low-rpm pull in 3rd.

Really enjoying the change

[2Times]

is there a changelog for v400?

[Bash]

Definitely a lot smoother, i do however feel the surge has been brought back in the rpm, meaning it used to happen between 3k and 4k now its around 2k, however very difficult to replicate or notice. I was trying consistently to.

Dare i say that COBB with these maps have the best OTS tune in the BMW world?!!!

[Cozy]

Can you go into any more details on the differences that you felt between v3.01 and v400? Does the car feel quicker, slower, what are its improvements?

[Bash]

I had a surge between 3k and 4 k which has been eliminated, much smoother than before, you dont feel the monster kick that i use to get on the 301 ST maps. My butt dyno tells me its slower, needs more adaptation or it maybe the smoothness fooling me.

I think the smoothness is fooling your butt..
I got the same first impression. But after some more driving, i think it´s at least as powerfull as 301.
And a lot more comfortable.
I like it a lot, and it feels like my AT does too

[Cozy]

I think I might stick with v301 for the punch in the back, unless v400 gives any significant inprovments.

[RimasRS]

Sorry guys just a stupid question to which I can't find the answer.
I'm receiving a COBB AP so first step should be that I'm connecting it to PC for firmware update? Or connecting it to the car for ROM recognition?

Appreciate...
