After dyno, and after 14 days of driving, if I don't like the result, I can always uninstall the software and go back to the factory setting, with all money refunded. So, I guess I can at least give that a try.
And yes, it's not like the old days, and if it was that easy, BMW or Dinan would have come out with their own long time ago.
I am only doing this since I had a great experience with my 2000 E39 540i. I ended up asking powerchip to tune it aggressively after the first installation, and they custom tuned the app just for me. I thought the result was good, but I have no dyno to back up my statement.
Hopefully after Monday, I will have some evidence to share with you all. I will be the first guinea pig so you can make judgment on what you see.
Wish me luck!

OK, enough indulgence in this nonsense, time to burst another bubble.

Since you hadn't bothered to search, here's a good thread summarizing the available chips, including powerchip, for the NA engines.

Chip ECU Flash Summary

What do all these chips have in common? fail.

ECU tuning is usually a waste of time and money on NA cars. You will get more hp and tq with bolt ons.

This reminds me of my E36 days when you'd break your back for 5whp here or 5wtq there.... And then you looked over the fence at all the ricers and their turbo cars which would net 50+hp for mere change....

My, how things have changed with the 335.... I forget how shitty it was to try to extract power from NA engines.... But, man, there was soooooo much you could do.... Headers/exhaust/cams/M50 mani/OBD1 swap/rear diff/ECU tune when done with the hardware upgrades.... It got soooo expensive.... I did all the work myself on my M, and even with the money I spent just on parts, I probably could have bought a turbo kit.... But, I digress....

I was using exaggeration to emphasize a point I was trying to make. I forget the literary term for it because I spent 7 years in the Marine Corps where my vocabulary was reduced to four words above four letters in length.

But congratulations for spotting the M-tech bits. Ya done good, kid.

Well, for your information, I have done much search with no success.
I have already visited the link you provided long time ago, and all of the links are either for turbo engines or 325/330. None of them has one for 328i. Plus, there's no mentioning of Powerchip in that link you provided.

I am not sure why you're so negative about something I would like to enjoy. If you don't like what you see, then just don't bother looking at it. There are many people, including me, who are interested in this stuff, and I just wanted to share the news with them. It's obvious you aren't one of them.

it is quite obvious that these other members have good knowledge about ECU flash, especially used on non turbo vehicles. They are entitled to their opinions even if it is negative. I mean i have a 328i and thankful that you could share this information but i too have doubts we would see much gains. You say there is a return period, so that is cool that you want to try it out regardless, just let us know how it goes.

Yeah, I don't mean to disrespect other people's opinions. Like I said previously, I will be the guinea pig, so you guys make your own decision after you see the result.
I think it all comes down to personal preference. If I like what I see even with the expense of software update cost, then I think it's worth it to me.

Just a clarification.

ECU tuning is the last thing you do AFTER the bolt ons. For MTs, ECU tuning affects fuel mapping and timing (shift points for AT). If a tuned ECU is the only thing you do, you are wasting your money.

If you upgrade intake, manifold, header back exhaust, port, polish, bore, compression and injectors, an upgraded ECU will make everything work together.

No negativity towards you intended.

I just don't want you to get your hopes up for what has been in development for 3+ years now. Whole bunch of tuners claiming to having chips for 325/330 a while back... got us nothing. No concrete dyno results, no concrete gain.

I appreciate you trying it out and reporting back the results nonetheless. I hope it really works this time around.

That really depends.. maybe it's not so great on BMWs, but in the honda world, ecu tuning can make significant improvements in power. Most of that is because of good rom editing software (like Hondata), that can be purchased and tuned by anyone, instead of getting it from a shop who sends the ecu out to some obscure place, and waits for it to come back reprogrammed.

sadly, nothing like this exists for bmw's yet.

I am sorry if I sounded a bit too harsh on your previous statement.
I didn't know this many people would contribute to this thread. I hope I am not causing too much trouble by posting the original message to the forum.

And yes, I understand the ECU tuning without any further modifications such as exhaust, header, CAI, etc, may be a waste of money. Since powerchip is giving me the first opportunity to try it out, I guess I will try it. If, however, it turns out nothing special, I will definitely ask for full money refund.

This will be my first dyno test as well, so overall I am very curious of what the software update will bring. I just hope that I don't sound like a rice racer who wants to do all ugly stuffs just to make the car go fast for stupid reasons. I hope what i try to do to my car is to make the overall daily driving a bit more enjoyable than what it is.

I know it is a blasphemy. I am driving a BMW, the ultimate driving machine, so I really shouldn't want anything more .

See you guys on Monday night!!!

sounds like something to consider, depending on fuel consumption etc...
after all, many buy intake / exhaust (bmw perf ones) for about the same price for less gains (albeit sound gains)

that is really unprofessional that you had to call them to find out the their guy was not going to show up for the appointment. What? the guy suddenly fell ill on the morning of the appointment? :thumbsdown:
