BMS Powerbox for 323i - more info?

Can someone provide me with some more info about the BMS Powerbox? I've read that the improvement in performance for my sluggish 323i can be quite noticable but in essence it like constantly driving it on DS mode. Is it really work the mod?

Any comments will be appreciated!

U can't feel very obviously the change by just gaining hps around 10, so, better save your money, this is my personal opinion.

In my opinion, modifying cars is not all about gaining an extra horsepower or two. My experience with the 323 is that 'sufficient' torque is only acheived at a relatively high rpm. Hence, this makes the car feel unresponsive and sluggish, especially when going up a hill or when the vehicle is fully loaded... and you need to select a lower gear earlier to keep the momentum going (in your case, through the use of the DS mode).

Having said that, I dont know anything about BMS Powerboxes, but the first thing I'd do is look for quantifiable factors, such as the power and torque curves (assuming that they have not been exaggerated), compare them with the original 323 and go from there...

steven,

I run the BMS Powerbox on my E93 232i.
I cannot say that I have noticed an increase in power. BUT, there is a tremendous increase in acceleration. To the N52, it is more a throttle mod rather than bhp & torque.
I would recommend buying and installing it...
You might though want to consider additional performance mod to bring your 323i to the Max performance its engine can get

I owned a E93 323i before my E92 335i, this E93 is really heavy in weight, 7 months had asking me to refill with 1.5L engine oils by totally 3 times, and got some loosing sounds occured from hard-top which is seem can't be fixed even 2 times were sent back to BMW and checked and fixed (they said). That's why I rather lost some money and changed to my present E92 335i. The potential of mod on 323i is relatively very low when compare to other models except 320i, maybe you have spent over 100K on modifying your 323i but is still considerly not very fast, that is why I thought to spend 100K on 335i rather 323i is more worth, anyway, this is my personal opinion only, u may not agree with me.

Happy New Year ^ ^

Renus> Just out of curiosity, when you bought your E93 323i, did you go for a thorough test drive before you put down your deposit? I test drove both the E92 and E93 323i before I settled on the coupe. The extra 200kg of the E93 was quite noticeable compared to the E92.

In regards to your oil consumption issue, it is common knowledge amongst E9x and E60 owners that these engines have a thirst for engine oil. Each time the low engine oil light comes on, no more than 1 litre should be added... although 3 times in 7 months seems a bit on the high side, unless you floor your car at every opportunity!

With the roof - BMW Concessionaires has an obligation to have it fixed under warranty and any substandard maintenance repairs should be reported and escalated!

Happy New Year!

Thanks for all your input ... so i guess its sorta no different from driving my car on DS mode all the time.

So do any of you regularly drive your cars on DS mode? Would it harm the engine in anyway? and how much more fuel consumption is there on DS mode?

Believe me, both bmw that I have bought were never get a test-drive, but my present 335i never asking me to fill any single litre of engine oil even same as 7 months have using it.

Renus: My reply will be divided into 2 parts.
1. I have been driving my E93 for 2 years now. I don't have a problem with the hard-top (noise, malfunction or what soever) knowing that I am person who drives with HT down anytime it is not raining.
In 1 year service interval, the "Check oil" have never been less than the Max. That is I do not run the problems you have stated above.

2. I agree with you, a 323 is not a 335 and will never be... The BMS for N52 Engines is designed for acceleration purposes and not to render the 323 engine as close as the 335. If someone is so obsessed to turn his 323 engine into a 335, he might need to install a twin turbo or a Turbo charge, etc and yet.. I am not sure if anyone really wants to go down this road.

I have spent over 100K for my mods, but they are not for matching the performance of a 335; they are rather esthetic/aerodynamics... If I got the 335, I would have spent this same particular money on it as well (money went for Rims/Wheels, M-Tech body kit, Suspension, etc..)

Happy New Year to all...

Hi Steven,

I will be strongly suggesting you to give it a shot and whilst, Terry of Burger Motorsport is very helpful in which, giving professional advice even at our local time!! In fact, I just chatted with him by email and he did response my email at such local hours, surprise right??

I'm not sure if the BMS Powerbox is operating by chip tuning just like the JB3 I'm using in my E92 335??? If so, it will be a fantastic news for you, Steven!! This is because Terry spent lots of times on R&D to improve + enhance his software!!! I purchased the JB3 around 4-5 months ago and the chip was equipped with 1.2 version of programming chip....today, I'm chatting with Terry to get the new 2.0 version while I have been tried the 1.3, 1.4 and then, my existing 1.5 final version i/o Beta Version!! My friend's E91 335 has volunteerily to be the guniea pig for Terry's 2.0 for testing purpose!! Another good thing is downloading the new version of chip is completely free if you have a chip burner and then, buying the little monster chip at Sham Shui Po computer market....... I don't see any other tuners can provide such service and again, I just bought the JB3 PNP for 4-5 months time!!! Thus, don't wait and give a try....... Terry does send int'l though.

Cheers,
Matthew

Hi E93 DT,

You should go to the BMS website to check for more details!! Since mine is a turbo, the gain is pretty substantial in which, it is around 50 HP and 60 lb/ft torque added according to the Bavarian BT code scan dyno run's data record!! I'm not yielding the high boost maps' set up, while I'm merely running map 5 to wait for my DP sent it over! If I tune the program to Map 7 with the DP, the result will be more progressive......

You can check out Terry's website to get more info as below;-

This is only an FMIC..... (Front Mount Intercooler)!! JB3 is a piggybag tuning chip...one is software and the yr link is a hardware??? However, you gonna need the bigger cooler to replace the existing one if you wanted to yield for much of the gain!!

yep, it just front page. All processor,blow off valve kits are inside. I also found installation manual there.
Just not sure which band is good

Hi E93DT,

I strongly recommend you to read more of those users' comment in our E90 forum especially on the Turbo Bimmer's section!! You will see different members have different views which even provided w/ Dyno Graph for comparison using the fact to proof which Tuners can run faster!! Then, you can come up w/ the one you like the most in refer to yr driving style!!

As a reminder, I've heard some users were saying the Processor has pop up the fault code of 30 FE which is frequent limp mode situation especially during cold start in the morning and then, press it hard!! Not sure if the Tuner has fixed this issue though??

As I've elucidated my choice on BMS, this is because Terry is super helpful and I have a few buddies using the same JB3 BMS set up in HK whereby, we can chart and exchange the good/bad experiences we are facing from time to time, together w/ the parts we added to yield the most output! If I go for Processor, I've got no one to share the problems and headache when the problem is related to the its software caused by Tuners' software bugs ! We usually gather our issues/problems in asking Terry to check why and then, fix it all at once! This is just my choice but doesn't mean that, it applies the same to you!!

All in all, have fun w/ it as the researching period is what makes the whole Tuning & Moding process fun in getting to know more abt yr vehicle.....Then, you will start to appreciate the manufacturer even more for such masterpiece of N54 engine design!
