I've been searching on the forum for tunes for a 330i e90 and all the threads I found regarding this were old. So looking for more recent info.


Found
-Active Autowerke stage 2
-Turner motorsports
Found some others but didn't find that much info

Active autowerke seems to be the best option right now. Anybody else have that tunes or other tunes that can clarify how good or bad they are?

Long term reliability and enjoyment of the tune?

Thanks!

Search harder. BPC is winning the race right now.

[Ruddigger]

Stop looking.

[tdavis42]

BPC is the way to go. AA only seems to have the tune because at one point they were interested in the N52 engine. The guys at BPC are currently interested in and developing new power systems for the N52. For me it was a no brainier.......Support those that a. Know what they are doing and b. Actively supporting the community.

Obviously didn't search hard enough, BPC is all over the place now!

Hey quick stupid question that maybe one of you guys can answer-why is the tune info/dyno graphs identical between the 325i/328i and 330i tunes?

Same engine. Just different intake manifolds and software.

That I know, but how is the initial output and tuned output identical on both cars? Is the 325i/328i dyno graph and numbers ONLY with the 3-stage manifold? And they both can expect identical gains?

[twastheglow]

On a side-note, I'm shocked to see an almost 27% drivetrain loss on a RWD 330i (yes, I know that a 10 year old car has probably lost some of it's original power over the years, but still...).

I'm pretty sure they just used the same dyno graph. I would hope most people who are going to pay to get a tune done on a 25/28i, would have already upgraded the manifold.

Ah, ok...so that answers my question. They're the same graph because they're using the 330i graph with the assumption that the 325i/328i peeps will be doing the manifold upgrade. That makes sense. Thank you.

Still can't believe that drivetrain loss though. That's depressing.

I would hope to see someone who would buy this tune and add some before and after review or dynos to make sure it matches what they claim. 675$ is not a cheap one

Their all over the forum...just search.

[ycehcky]

The gains will probably less noticeable for the 330i, since the end result is the same amount of Wheel hp for 325/328/330.

[hassmaschine]

I think if you have a stock 330i the peak gains are about 10whp but there will be part throttle improvements and more low end torque, plus a more responsive motor, no soft limiter, etc.

Everyone looks at a tune and only thinks about peak WHP/TQ gains but there's way more to it than that.

[3002 tii]

Anyone ever post before / after dyno on 330i 6mt with headers and tune?

Only a couple threads I've found for 330i's that seem to be about a tad over 210whp. There is the NA dump thread but I'm too lazy to fish through 30 pages to find a bone stock 330i dyno haha. I'm stock tune right now on my 330i 6mt. Only thing different is just the 3 inch intake hose and drop in filter with charcoal delete. I'll get a dyno done once I get my exhaust redone and get some afe race pipes. Won't be baseline though unfortunately.

[hassmaschine]

mine was 218whp stock (STD correction).

A couple years back, most said go with an AA tune- at the time the AA tune was in favor. My Z4 (n52,e89) took the tune well, I have been pleased (always want MORE). My 30i zed and the stock 330i should come with the same tune from factory, the AA tune added several HP (but as Hass said, helped through the entire driving range <butt dyno>).

Now it does appear BPC is the tune of choice. Looking at dyno numbers looks great, but conditions and the dyno itself varies so widely getting accurate results that are true apples to apples comparisons. Would love to see dyno results (from the same dyno, same conditions) of AA tune and then a BPC tune to see the results. In no way am I doubting BPC may well have a better tune, so starting with the best choice makes sense- buy once, cry once.

Has anyone here actually had both? Where are the gains and is there any downside compared to the AA tune? While I enjoy my AA tune, more HP would be better. I would never advise anyone to purchase their AA tune without looking at BPC first.


Note: My Z4 mods are simple, AA tune, K&N filter with charcoal delete and only top shelf fuel. This K&N did foul my MAF but was easy to clean (mileage numbers returned and stumble gone). My airbox and ducts had plenty of casting "slag" that had to affect airflow minutely, so I cleaned up the air box and ducting (minimal affect sure, but why not?).

Sorry if this kinda derails the OPs questions, but my feedback on the AA tune is positive for maybe 10k miles so far. BPC looks to be a friend to the N52 motor, but AA deserves praise for their support also. Maybe AA headers in the future?

Good luck OP, the tunes available do improve drivability and worth the cost even on a 330i/30i. The gains are not nearly as noticeable on dyno peaks compared to 325/328 n52 cars. Different dynos, different results, they all show gains. Anyone tried both?

You raise very valid point.

I am currently on AA headers and 3 IM tune. In coming weeks I am thinking about dynoing AA tune, purchase BPC tune and do dyno on it as well. It would be the same car, same mods, same machine. Maybe do a test runs a week apart, so the car has time to fully adjust.

[boro92]

W37V that would be awesome.
FWIW I would lean towards the BPC myself as they do away with the "4th" stage DISA event and alter throttle response (which AA does not do either of these things).
If the BPC tune also changes the power profile (or whatever it's called - Hass documented this in his thread), then all the better. Changing the timing of DISA opening and closing would be beneficial for a better power curve.

This would be great, if you can. I considered adding headers and another tune. The cost difference matters, unless the BPC tune is clearly worth the difference. AA will update my tune for $100, or start-over with BPC. Your results may well help me decide...

I guess our Simon tools are not needed for a BPC tune?

I will look for more threads on BPC tunes- I am not keeping up I guess.

Edit to add: I know doing 2 dynos adds to your expense, would be a great service to the community and appreciated. An apples to apples comparison would be fair, and easier to understand than the butt-dyno (yours may be different from mine). BPC will surely win, but by how much and where in the rpm's?
