Wow... Should we open a separate thread that starts with this post so we din't loose this discussion? This sounds to me like very knowledgeable information.

The question: why 330 software needs to be flashed? The assumption at the board is software is identical, but behaves differently based on VIN #

[e90pilot]

I don't remember reading any assumption the the software was identical. In fact, just the opposite is true. The software on the 325 is different from the 330. The reason BMW techs can't just flash it to your car is because of the VIN. Some people can change the option list but not your average tech. If you try to force it on, the software vin will not match the cars VIN and that will cause issues. I think XDR's post fixes the issues.

Ok, maybe I misunderstood something, but anyway, XDR sounds like he knows something.

Personally, I'd prefer to convert my 328i to 330i factory settings. I don't like the idea of after-market tuning... And I do not believe after-market shops are able to utilize 3-stage manifold advantage as they simply do not have enough knowledge and equipment.

325 328 dme software do not recognize Three-Stage Intake Manifold
flash 330 software necessarily

...may 325 tuning software recognize Three-Stage Intake Manifold ?

e90pilot try remove connector from DISA actuator motor and read error from DME
or test DISA actuator motor DIS or ISTA/D

if error not will appear 325 tuning software do not recognize Three-Stage Intake Manifold .....

[e90pilot]

Let me try that. I do know the factory software will operate the DISA motors at the correct rpm. Maybe it doesn't look for faults. I'll check with Active Autowerke on this. I'll unplug a DISA motor and see if I get an error.

[mike-y]

I can also confirm that the DISA motors function with the 325i DME. I tested them before installing in my car, and both opened and closed at the appropriate RPMs. The valves may operate on a passive rpm signal, without being monitored by the DME.

@XDR, what enables you to align the DME and CAS?

Is the process all done in the DME?

because I'd like to try a 330i DME instead of reflashing my original 325i dme. thanks

[5erman]

are people really stillll discussing this? This is like 5 years old of information. it is NOT possible folks. You can get extra power but nobody yet has reached the power of a 330i from a 325/328. Its just not happening

LOL, so true...

(and part of the reason being, experienced people aren't willing to share new information... and I don't blame them... why should we? everyone presumably already knows everything there is to know about this motor right?)

[BudVlad]

325i software will recognize DISA and operates the flaps (tested on dyno).
I had 330i software loaded into 325i ECU but the car lost power and I had to reload the original software.
With tuning you can get more power from 325i (3l engine) than standard 330i. I’m not the only one who done that.

yeah,

but I don't think anyone has actually taken a physical 330i DME (or even another 325i DME for that matter) plugged it into their 325i and got it to work.

if anyone know how to do this, please share. this would be a great help.

[BudVlad]

As far as I know nobody successfully modified 330i software for 325i. Tuners are modifying 325i software.

This not help . After changing DME need change ISN in CAS or ISN from your CAS write
in 330 DME .After this the car lost power, same if 330i software load into 325i ECU . But if in CAS change coding CLASS_PWR keine to klasse_2 all will be ok .
If buy key ,CAS and DME from 330i only need coding CAS according your VO (option list )

dziakuju (Thank you) xdr!

What do you use to code CAS and DME? (BMW tool?)

ISN = VIN / Mileage?

[Mike.Beale]

Was just doing a bit of surfing on RealOEM and it looks like the US Spec 325i/330i uses an MSV70 DME unit. It looks like the 128i/328i N52 or later European 330i use an MSV80 DME unit, and the N51 128i/328i use an MSV80.1.

Does this mean that those of us that have 328is (or a 128i in my case) would need a DME (or at least the software) from a European 330i (or 130i) to get this to work?

Yes, I believe they switched to the MSV80 because of the GM transmission.
Anyway................


@XDR

Will this work for coding the CAS and DME?

dude do some searching this topic has been hammered to death and nobody with a 325/8 has dynoed a car producing as much as a 330 so budvlad stop spreading lies. No tune of a 325 with an 3 stage intake is going to make 330 power. The tuners have not got it down like the bmw engineers.

If you did some searching you would find that I posted dyno at least twice. Than don’t lie. Since 2007 325i is using identical engine as 330i. It’s no brainer that with tuning you can bring the power to the level of 330i. I had my car tuned by DS Motorsport. The guy is building racing cars over 20 years.

BTW: Wintertuning (Forstern, Germany) is claiming 201 kW (273 hp) for 125i/325i . He does the tuning by downloading the original software to his notebook and sending it to somebody who works for BMW AG (according to Winter on software development). However, unlike DS Motorsport he doesn’t have dyno.

Dude, who the hell are you to come on here time after time and call people liars? What are your qualifications? You add nothing to this board. All you do is come on time and time again and complain and shoot down people's ideas with nothing to back it up.

I have an '06 E90 and i approve this thread. we need a conclusive method to completing this conversion already ffs.
