You cannot. No.

Read this. Come back if you have a question that is not covered in the FAQ.

I've been chasing an issue with boost lag for weeks now and I believe the conclusion is that I fall in this category. I stopped by the dealership to see what they have to say and it turns out that I'm outside of warranty and they will not cover this service bulletin. Can somebody tell me if anyone has successfully programed the ECU at home?
Thanks

Most dealers WILL update your engine's SW for an hour or two's labor rate(ie $120 to 240 USd). Tell them that you will pay for the SW update... that should be music to their ears.

29.2 simply refers to the BMW software version in use at the time to reprogram control modules (i.e. Progman V29.2).

To determine which software version your vehicle was last reprogrammed with, you first need to know its current integration level.

During development of a given chassis (i.e. E90) and subsequent upgrades and/or fixes, integration levels are defined. An integration level is a defined vehicle configuration from an electrical standpoint (hardware and software) that is validated by BMW. There are three integration level states:
  • Plant -- the integration level of the vehicle when it left the factory
  • Dealer -- the current integration level
  • Backup -- the last integration level
The integration level designation is comprised of the system reference, SOP date (SOP=Start Of Production) and the I-level.

Example: "E89X-13-07-501"

E89X: System reference
13: Year of introduction
07: Month of introduction
501: I-level of the system reference

If you have a K+DCAN cable, you can use INPA or ISTA/D to display the integration level. Alternatively, you could ask your BMW dealer or indy to look it up for you.

To display your current (dealer) integration level with INPA, go to E90 -> Select E90 -> Functional Jobs -> <Shift> + <F2> Vehicle data:


Integration levels correlate to Progman (older) and ISTA/P (current) software versions. Google bmw group ista/p version and i-level overview and examine a chart. Here is an example from ISTA/P P3.57.0:


If your current integration level is "E89X-14-11-501", the vehicle was last reprogrammed with ISTA/P P2.54.3. In which case your vehicle is "post 29.2".

Another example:


If your current integration level is "E89X-08-03-510" or earlier, the vehicle is "pre 29.2".

You can use WinKFP expert mode to downgrade your DME to whichever software revision you wish.

See this thread for an overview of the process:
http://www.e90post.com/forums/showthread.php?t=1259232

My post in that thread includes a link to the WinKFP expert mode programming guide.

SP daten 29.0 contains all of the "pre 29.2" software revisions for the MSD80 and MSD81. It aligns with integration level E89X-08-03-510.

I would highly suggest against actually downgrading. Updating the DME to the latest version and then performing the wastegate conversion in ISTA /P is the proper and effective way to solve the issue.

I would second this.

In my case got horrid wastegate rattle (because they are worn bad which was masked by the old software).
Re-adjusting the rear rod got rid of most of it (not completely) but the car feels so much better without lag. Drove like 3 yers with lag without knowing it, now car performs soooo much better.
Just use ISTA /P with retrofit option, since adding the d-(or K-?) word via WinKFP doesn´t do the trick (missing the proper DME maps I think)

Correct, adding just the VO code won't change anything; it needs to be flashed in.
