Just guessing here:

If the "wastegate conversion" option is absent with cars >09/07 and the technicians have only looked for the option with such cars, they may have fallen for the false impression that it is not available any more.

The alternative were indeed very disappointing: Your observations would go in-line with the following theory for software >= v33.1:

- Cars >09/07 get the wastegate conversion per default.

- Cars <= 09/07 get some toned-down lag fix to reduce rattle, but with less lag than the dreaded v29.2, much like v31.1.

If this is the case, I was lucky to get v32.1, when "true" wastegate conversion could be selected. If I get another update, I will look out for changes in behaviour...

I see... So when I say that 35.x feels snapier everywhere then 25.x even without tune, it means that the conversion was implemented? I would think so.

Yup. Seems so. And if it is even snappier than v25.2, I doubt that you are mistaken. But if Mr. 5 is right about his pre-09/07 car with v33.3 having open wastegates at idle, and your pre-09/07 car apparently has closed wastegates, I would conclude that the option still exists - otherwise I don't get why your cars should behave differently.

Since v32.1 was the last version that could also be applied by using Progman, whereas all versions above that have to be updated with ISTA/P, I get the impression that at least some technicians did not look out hard enough for the "wastegate conversion" option in the ISTA/P software, which was all new for them at that time.

The "wastegate retrofit" setting is believed to have become unneccessary from v33.1 on, but that was never verified, only reported by some people here. The original SIB 111307 still says that the "wastegate valve conversion" can be selected on request with cars built from June 2006 up to September 2007. Maybe the option is absent (and thus applied automatically) only for cars > 09/07...

So: did you specifically ask for the conversion after the update? (I did, but I absolutely had to with v32.1)

I always wrote, "apparently" the option has disappeared from the ISTA/P menus. But with cars built before 09/07, I'd rather request the wastegate conversion to be done, just as a no-regrets strategy.

Yes, I made sure that I got the "lag fix" option if there was an option (I can't remember if there was one or not but my friend knew what I wanted). My friend is the tech so I had nothing to worry about.
All I'm saying is that some cars do not automatically get "fixed" with the newer software versions. But then again, I don't know if the newer post 33.3 versions fixed this.
No matter what, I'm extremely happy that GIAC has made their software exactly like the pre 29.2 versions so no matter what BMW gives me, I will always have my lag free GIAC software.

I got flashed back to GIAC stage 1.2 after my 2.35.4 update.

I can feel the difference in power and throttle response again with no lag. i only had a couple of opportunities to push it and boost peaked in the 11-12 psi range, but it was easier to hit 8-10 psi in normal driving situations after the GIAC flash than before.

Temps were in the low 20's so I am positive now that the low boost figures are attributed to the lower temps now that I am flashed back to GIAC.

I must say that 35.4 far better then my previous ecu version. I own a 11/08 build 2009 e92 and suffered from turbo lag, rough idle, and backfiring exhaust. 35.4 has fixed all these issues along with idrive glitches. I think BMW did it right this time.

Yup, the 35.4 seems like the best so far.

NRG, the bucking sand hesitation was something that was fixed by a SIB from over a year ago if it is what i had. It usually does it when cold and when pulling away from a stop in first gear. I dont have the exact bulletin number but it subject is sopmething like Hesitation and bucking when accelerating. The fix was a software update, probably 29.2 since it was a pretty old bulletin.

Most probably! I jumped from 25.x to 35.4 and missed everything that was in between.

[Quisp]

That was the problem that I took it in for when I got 29.2. I would prefer the lurching and bucking to the "hit the gas and wait"

[cn555ic]

So is the 27.xx software the best out of the bunch?

[citrixscu]

28.xx probably. I believe they refreshed the iDrive firmware in that release.

No! The 35.4/36.x feels much better by a margin.

saw this a few days ago:
http://www.consumeraffairs.com/news0...12/ca_bmw.html

Fairly poorly written article (revelations per minute? Hallelujah I have seen the light! And again and again!), and doesn't tell us anything we didn't already know, except that there is now a class action in CA in addition to the one we know about in AR.

Been a while since I've been here, I know. I took delivery on a new '09 a few months ago, and it drives much better than the '07 ever did post-29.2 (except those DAMN RFT tires I can't wait to get rid of), and I attribute that to the new ECU and software. However, even though it's been 2 years, I still remember pre-29.2 being more powerful. I gave up trying to squeeze that last little bit of "monster" out of the engine and have been enjoying my new car since. The lag in the '09 is not bad enough to get in a daily lather about, and they made me a good deal on the new one. (Yes, only a little sorry to say, I was bought off -- but the old runaround was driving me crazy and getting a new one was win-win.) Some day when I get more time, I'll post all my observations of the differences between the '07 and '09.

[chromisdesigns]

Had the s/w in my early build date '08 updated from 29....to the latest level in November. Fixed the turbo lag just fine, too. But almost immediately, a fairly loud wastegate rattle developed. The TSB even warns about the noise.

I'd rather have no noise and no lag, but am willing to live with the noise if I have to. The lag was ridiculous, though.

Anyone else have the noise show up after the lag was fixed?

[Quisp]

iScream, how you been?

Didnt know about that california suit, interesting stuff.

My car was running like a sick dog for so long I cant remember the last time I was having fun driving it rather than disappointment.
Seems like things can get worse even when you think they cant.

Quisp,
What's the story with your car now? BMWNA still refusing to upgrade to latest SW? is your ride still Dinan tuned or is it back to stock?

You really need to get that sw upgrade, surly they would do it if you pay for it? It's worth it...

[Quisp]

Actually the dealer refused to even look at the car whether i paid or not. Went backand forth with them and told them Dinan would pay and they wouldnt even let me bring it in. Being flagged is not a good thing.

[ChrisK]

So what is the newest version right now? v35.4?

I have v29.2 on my 135i and I am getting the Alarm programmed on Monday, which means I will get the newest software.

I also have the older DME80.

[ChrisK]

I just went from v29.2 -> v36.5 and the difference is amazing!

[grubster]

I have an '07 e92 335i with manual tranny. I believe it had a software update back in '07. I have a small glitch on the radio where it sometimes loses the check mark next to the preset station I am on. They said they would do a full software update to fix it? I was hesitant due to lag issues, but what should I do now? Don't want to risk having problems?
Also, will the new software prevent me from tuning in the future if I decide to? Right now I have done nothing to it and don't plan on it, but you never know.
