I know for 6MT 330is, they can run low-mid 14s depending on track/traction condition.

What about 330i 6AT guys? Anyone been to dragstrips? Most told me we will trap 93~95mph with anywhere between 14.7~15.0.

With all the hype about PBX and all, no one is proving it with results. Dyno gains are too minimal to make a decision. I might hit up the local drag strip to get before/after times of PBX to end this hype after all. There is Northwest BMW dyno meeting so I might even attend that.

i dont give a shit about the gains that pbx gives, the throttle response alone is worth the $300!!!

You want to get real gains, get a 335.

Throttle response blah blah blah has been going on for the last 158304 pages of PBX related threads. If butt dyno is all you are pursuing for, then thats great. I want to see some real life numbers(past dynos).

Dyno results are proving that PBX isn't a joke(since sound a little too negative) and I certainly appreciate fellow vendors/sponsors in this forum dedicating to performance of unpopular N/A E9Xs. I just want to see if all the hype you guys are creating is real before I make the purchase. Call me too-careful, but Im not about to waste $300 for "oh-it-feels-better" kind of bullshit.

Why isn't anyone posting some serious video analysis of this mod if this really is all-that? Just a little frustrated. Not to offend anyone. The burn-out video was badass though.

i am curious too about seeing some hard facts. i want this mod if it works.

what does it actually do? i have heard about the throttle mapping, does it change fuel delivery and timing also?

what exactly is throttle mapping anyway?

when it remaps does that mean 10 percent throttle is now 20, 20 is now 30, 30 is 40?

if that's all throttle remapping is, then isn't it true 100 percent is 100 percent no matter what?

So if i give it a little gas coming off a stop, instead of acting normal it acts like i gave it half pedal or more? If so that would make me feel like i have more HP but really its just hitting the gas pedal harder for me, which i could do anyway if i floor it. Does it just make the pedal more responsive?

forgive my ignorance.

Numbers are going to be small if anything.

0.91 second average gain is rather "big".. Im actually impressed if that video is true.

The only thing i can suggest is drive a 330i with pbx, and you'll feel the difference.
I put the pbx on map 0 (stock) and i swear i couldn't believe i was driving the car like this lol.....it felt sooooo heavy, its unbelievable.

What kind of videos do you want? I'll try to get some for you

My car peels out soo easy now, i love it

To be honest, I tried that with my car, and i was getting the same time with and without the pbx.....it can also be that i pressed the stopwatch too early or too late.

How hard is this to install?

my 325i 2.5l
0-100km/hr increased 0.9 sec with pbx

So the car is slower with the PBX on?

[lux.sh]

Overall gain in speed might be slower, while the "sweet spot" for PBX application is what the video is showing. 80-120km, pbx definitely pulled harder. I guess it doesn't perform as well in the lower-range.

Man, only if I someone with PBX lives next to me...

[csupernova]

me too. been thinking about installing the PBX but the possible long term ill effect just scares me. I'm not saying it will do any harm to the engine, unless someone has tested this device for a loooong time, I can't convince myself as I intend to keep the car for at least another few years.

[G35to330i]

Scared of the powerbox? I wouldn't worry about it at all - the changes are fairly minimal - it's not like you just adjusted the wastegate on a turbo car or changed pully's on the S/C car to achieve some amazing new numbers. It's adjusting A/F and timing slightly - not a giant deal in the automotive world. So don't fear a PBX. I would imagine driving habits are the impetus for greater wear/tear than a simple PBX mod.

And you're not going to see any massive gains on our NA cars - just the nature of the beast and it just won't happen. To see (easy, cheap, simple) massive gains you need to have some sort of forced induction (as mentioned above) and adding that to our cars has proven ridiculously expensive.

I recently installed one and while it's slightly more involved than making a PB&J I wouldn't say it's hard - just be careful and pay close attention to what you're doing and you'll be just fine.

well I plan on keeping my car for another few years so if you want to wait I'll let you know how it is in another few years

There was a serious video of a 528i showing 0-60 40-80, etc times before and after a couple of months ago.

[Wlew]

As I said in another post, I have always raced with my friend who drives an E36 328. fully tracked out (chip, intake, exhaust, racing diff, role cage, completely gutted, etc) its like a tin can with an engine. very quick. and before the pbx he would always zip away from me. zip as in would walk away, not run away. hands down big difference and would always win.

after the pbx, I launch quicker than he does, and we are dead even after that. even if we go 20-80 or 60-120, we are even. he was rather impressed with what it did.

So yea, the throttle remapping is great. its liek you dont have to push the pedal so far down and when you do tap the gas it is instant no lag. sure, you could floor it whenever, but even with flooring it, it is quicker to respond. wont help too much in racing, its the HP and tq gains that come with it that really help. Which is proven on mine since he used to win every time. now we are dead even.

and before you even ask, no I cant post vids, because driving and filming at once is dumb, and I refuse to go to best buy and buy a video camera for you ladies to be "convinced" to buy one. haha. I will waste my money on future mods and not video cameras.

No front to yall, just not tryin to buy a video camera. You should buy a pbx. End of story.

[mike-y]

also, track times are often more inconsistent than dynos are. You are going to get different results without any mods whatsoever, so trying to go to the track to measure an 8-10whp difference isn't going to be so easy.

Well, actually, it's probably easier with an automatic, and if you get enough runs, hopefully you will be consistent enough to see changes in ET and MPH.
