E9X 330i Software

[Sinovich]

Speak to the tuners (advertisers) on the forum they will be able to advise you.

Around 5% - 15% max but you will have to spend on hard mods as the other posters have stated.

Think carefully as the need for more power will rear its ugly head. Try and spend some money on suspension upgrades first then play with the power

I mean this isn't expensive and it gives me options.

I would only do software and exhaust... I 'm not interested in racking up the kws, I just want a more responsive feel overall.

A full aftermarket coil over kit would also be a huge +

Has anyone had a full local exhaust put on their 330i?

Would I be able to do the BMS Box and a exhaust without software, or is software a must to take advantage of exhaust?

I also own E90 330i and currently preparing to do E46 M3 headers/branch swap and full decat.. KN filter and CHIP! Thinking also about diff swap... but that is when all my other projects finished :bangdesk:

How much is the e46 Headers/Branch and full decat going to cost you?

I have a guy who I would most likely get my software done with... he specializes in BMW, he did my Fiat Bravo... great results and service.

I already have the E46 branch and KN filter, I paid R2000 for the branch and a 1000 for the filter bad? I dont think so, my friend-exhaust fitter will let me work on my car in his shop and i wont pay more than 500 rand for the flanges.. I enjoy working on my car myself when I have time.
I would appreciate if you give me contact of your tuner.

I would always go the software route... I like being able to go back and have a few things changed and without having to bypass the ecu.

Would the cost of changing the diff really improve the drive? I have seen a couple people do it on their e46 on this forum.

I think it will help, surely. Especially on the 330i with our long ratio

Why worry about a turbo when you could go for this? :rollsmile:

Keeping it NA, there's not that much that can be squeezed out of the N52, but with all that's said about you can at least make it a bit more lively.

I have an e46 330i, contemplating putting on a full viper exhaust in the coming month or two. Looking at about 6.5k for a full exhaust.. Will contemplate a chip/software after that :thumbs:

 

[Dhp507]

Project Shift, Xcede, are on the forum..,,,then externally chiplogic are good with BMW's too

 

[K33G4N]

What about CAI, Branches, Full Exhaust, Some octane booster and Software ?

Should atleast give it a nice raspy tone and feel more responsive.

Maybe a lighter flywheel , So it will rev up quicker

Just suggestions...

 

[DieselFan]

Branches, freeflow exhaust, software will get you around 5-6wkw if done properly. Its not worth it if you after power.

If you want musical tones and a smoother rev range do it.

I know what branches and a good tune coupled with KN filter does, have you seen branches and cats BMW utilized in the 330i ? I have. For a performance motor such as N52, (200kw i consider as performance) its Horrific. Im sure i will get atleast 20hp atw!
Ive seen maxima 3lt NA with well designed branches and exhaust gained 35hp atw and no tune!

You cant compare two completely different engines. Lots of people on the forum have done these mods and there are only small gains to be had.

 

[akash]

I think they have reached the maximum power output on that engine.

Unless you gonna change the displacement, cams etc dont expect much gains with only exhaust and a tune.

Beside emission laws, it could be the reason why BMW put an end to the NA inline 6 enegine line and went turbo

 

[MKVally]

i say make sure the car is 100% healthy in all aspects
then full branches and zhorst
then software

this should put a smile on your face even if its N/A
although the figures wont be much but im pretty sure the drive will improve by a noticeable difference

I did not try to compare 2 engines! I said good gains can be had from proper branches on NA car!
Looking at the 330i stock branch I can say its crap! Too much backpressure from the 2 small cats sitting right after the cylinder head then another cat in the middle.. There is no scavenging from the cylinders when you have backpressure! That leads to poor performance at the top of the rev range. I understand BMW engineers had to find compromise between price-emission-performance. Obviously performance suffered here. Fortunately we are not obliged to have a Catalytic Converter in SA but in the rest of the world it is compulsory!

Is that viper exhaust from headers all the way down?

 

[Sherwin@xcede]

Ya ya ya

I've read that the throttle response can be increased dramatically actually.
Surely that would result in much better 0-100 times for example?

Hi, better throttle feel results in exactly 0.00% better acceleration.

In a 330i, expect 5 up to maybe 10kw more if you lucky. You might feel the difference, but most likely not really. Might have a bit more mid-range torque & very slightly better consumption on the open road.

Is that after doing the software? 10kw is 13hp! haha i think after all those mods on my daily driver i wont stop and will just drop SC in it hahaha :roflol:

I am not sure how much different the E90 and E46 330i is other than being N/A for the purpose of this thread.
But on my E46 330i I've done the full decat and exhaust at Speedway for R3500 and the Unichip at RBTS Racing for R3200.
According to Ross the stock 330i makes around 117wkw in his dyno and mine made 121wkw. So I can say that the exhaust system gave me 4wkw.
After the Unichip The figures jumped from 121wkw/241nm to 132wkw/266nm.
I pretty happy with the gains for R6700 spent. And u feel it on the road.

The torque delivery is further enhanced changing to the 3.38 diff ratio courteousy of Gizmo.

So as I said initially I don't know how much more different the E90 is but this explanation was to illustrate the gains on the E46

 

[HellfireZA]

@YUBEN Where is Speedway and do you have a sound clip of your exhaust?

Like i was saying, from 117kw to 132kw, 15kw is 20hp. This is good gain!
Thank you for sharing!
I expect a bit more gains from exhaust on the E90 330i as it has more volume of exhaust gas leaving the heads, due to higher output stock but the branch design looks identical. Anyway we shall see when its done.

 

[Yuben]

Go to th Advertisers section. Ralf has a thread on my setup. There are sound clips as well.

My 330i will be at the Charity event next weekend if you wanna hear it or go for a drive to hear the sound.

I just read this now, indeed it is. My friend did his e46 325i at Viper and it sounds great! :thumbs:

After doing a lot of web research I can officially say that FULL exhaust replacement: Properly built branches, downpipes and muffler gives up to 35HP on the N52B30, on the average this number is 20HP!!! without even a tune! Apparently car's behavior changes dramatically too.
Tune on its own does't give much say in 10HP range on average and intake 5HP(Induction). There are also plenty on NA N52's in the 270-300WHP (race) range as well.
Has to be proven but looks legitimate.

Hi Guys,

Based on vehicles that we have tuned we have achieved 13kw and 18nm of torque which is considerably more than the 330i's which achieves 8kw and 10nm.

More torque, more responsive and will rev up quicker in mid and upper rev range.

 

[Philip Foglar]

One thing to consider when looking at overseas (US) 330i's (and 328i's) is that they have the US style emissions intake which has a restrictive carbon filter after the air filter. One of the first (and possibly contributes to the stated gains) things that they do is swap the standard intake out for the Euro style type which is what we have on our cars here. This does not have the carbon filter and instead of the pad type filter is has the cylindrical type.

With better breathing, the exhaust is next. And I have also noticed that they tend to do a full exhaust system with headers etc. After this, a software tune and you will then have worthwhile gains I reckon. I am just not a fan of the sound that most of their exhaust system make - for me somehow it loses the typical signature BMW sound. But each to their own...
