You can just flash a stock file that matches the MI20S program. RSA only cares about a valid signature, you don't need to flash a stock program.

In this case though the dealer is insisting on stock software, so it's best to just flash everything. I believe the original problem is the module was way out of date before the tune was flashed, which caused issues.

[nsjames]

it must be pretty software specific, as mine was still carrying it's factory 09/07 software and I haven't had any issue.

For 06, 325i and 330i have different part numbers for the automatic transmissions (and different rear end gear ratios). The transmission ratios appear to be the same. Is there a 330i transmission flash that needs to be done to match the engine?

Thanks for this awesome thread!

[hassmaschine]

Yeah, I'm sure there is - maybe we could add that as a std upgrade for people with the 325i.

Not sure if there's a comparable update for the 328i/GM trans, unfortunately.

Thanks that would be great. So the 330i version of the ZF trans got different software because of the different 330i power band and rear end ratio?

Yes,

Shift points and TCC lockup points are adjusted to suit the power band.

You will like the 330 trans tune if you have upgraded the intake manifold and tune on you 325.


Hass, I remember building a Teaser tune for Bimmerlabs that turned on the gear display, maybe one or two other tweets can't remember the details.

Great news. Anyone ever swapped out a GM trans for the ZF? After I do my current 325i, I am going to do a full 330i swap on a 2011 N52 328i. I think some 2 door 328i came with the ZF from the factory so hopefully it won't be impossible.

Euro LCI 330s got a GM transmission. I think someone here flashed that with good results.

Edit: Caveat with the GM transmission in general is that it's susceptible to the D-CAN bug. Unless it's a very early model that still uses a K-line JBE, flashing the GM transmission will require the BimmerGeeks cable / EdiabasLib firmware, or something like an ICOM or Omitec interface.

I think the E89 Z4 3.0 came with a ZF gearbox. So there should be ZF software available to work with the MSV80.

hassmaschine, any updates on RSA delete and 325i —> 330i tune for the N53B30 people around here?

Still waiting impatiently

this.

I've talked with Dylan over at bimmergeeks, he has the software numbers.

I haven't had access to an icom cable, and I'm not willing to try a 6 hour flash on my can cable, so I haven't attempted it.

my brother will be upgrading to an X5 soon, so he'll buy an icom cable and I'll mooch it.

[hassmaschine]

The bimmergeeks cable can flash your transmission no problem. It's not going to take 6 hours to flash (maybe a couple minutes). but absolutely do not use a generic $20 D-CAN cable!

[nsjames]

I was under the impression that it was going to take hours from the people I had talked to.

guess the GM controller can speed just sucks massively.
I'll hit him up again about it.

Hass is correct, the TCU calibration file will only take a minute or two to flash. My old Z took two minutes while Dylan mentioned something like one minute on his E90 using the Bimmergeeks cable.

Unlike flashing the DME, flashing the TCU will not keep the fuel pump running so battery back up is not really an issue.

Does not take hours. And ICOM won’t be any faster than the pro cable for this task.

Absolutely have to use a pro cable though. Anything else is a guaranteed brick.

[nsjames]

yeah, I may have to update the entire firmware, not just the parameters, as my software is ancient in the car.
that may be why the long time was told to me.
hass had similar concerns about the ancient DME software, but I lucked out on that.

but if it is indeed possible withthe can cable, I'll have to bump this up on my priority list.

[Pinscher]

Do make sure you start with newest software before ruining these tunes..i got into a hell of a mess with my DME disappearing while going back to stock.

My new software DME lost communication to my old software GM Tasmanian and there is an fault code now...not sure how to fix it yet.

{Subscribed} Pretty sure I have fairly current firmware, but still interested in the process/progress.

[vilord]

Ooh, I'd like to update the shift points on mine too.

Any idea what is ideal for economy? For more power?
At least in my TT, better economy seems counter-intuitive, and I need to rev higher than expected for better gas mileage.

Since mine is a 6MT I'll have to update the software between my ears...

Nope. Entire flash takes ~15-20 mins, not hours. Parameter flash is basically 1 minute

If you want to update every other module on the car, yeah that’ll take hours media modules in particular). But that takes hours with an ICOM too

then I am corrected.

how does one go about finding the correct flash for this?

I remember the dealer doing a fairly simple job for me and decided to update my software for me as well....turned into a four hour affair.
