and my hood is not well bu the way, Moscow has already gathered to reflash 5 people (guys who do it, do not live in Moscow) It is possible for: 116i -> 118i 316i -> 318i (136 hp to 170hp) 320i -> 328i (184 hp to 245 hp) 520i -> 528i x1 2.0i -> x1 2.8i x3 2.0i -> x3 2.8i z4 2.0i -> z4 2.8i I think if the United States would be willing to re-flash the 15-20+ cars, our guys could come to you too |

^^^ How come no one in the US has done this reflash (x20 -> x28) yet, especially reputable tuners like Terry, Vishnu, Cobb? The potential/demand for this could be huge.

Because it sounds like BS. Notice no mention of dyno or other solid numbers to back anything up.

You have to remember all this ECU cracking data is coming from the guy who opened his hood while driving fast to "cool his engine down" Sorry but after that the credibility of the poster went out the window. |

wonder what evidence would you believe
dyno? but i can show you guys dyno from 328i stock as well as any other data like a racelogic or 1|4 mile time You can always find some reason not to believe. We have many people in Russia reacted to this possibility skeptical as you But then there were 5 more machines flashed How come no one in the US has done this reflash (x20 -> x28) yet, especially reputable tuners like Terry, Vishnu, Cobb? I do not know, may be because that is not a simple box, which they can easily sale. It's a long procedure takes 4-5 hours, well, still need to think of how to do it all Last edited by ilya_treg; 08-24-2013 at 01:52 AM.. |

Guys, you can not believe. But facts are facts. This weekend will be reflashed int0 328 for about 10 cars. Reflashed 320xi goes on Dyno on Wednesday to see the real result. But the drags with 328 shows that speep of reflased 320xi is the same.
The White one is reflashed 320xi. The Red one is 320i stock. Reflashed 320xi vs. 328xi stock with downpipe. Surely your tuner can also make this procedure, but apparently there are questions the legality of the use of original firmware BMW.

I can confirm that it's possible to reflash our car's ECU. I took a ride on my friend's 320 reflashed to 328 - the difference in power is huge (I own 320 myself).
I think US tuners know that there is a possibility to reflash the ECU and make 328 from 320, but piggybacks are way more profitable. Piggybacks can be shiped any place in the world and they easy to remove to keep the warranty. Whereas to reflash the ECU you need to bring the car to the shop for at least 5 hours and procedure of reflashing involves physical opening the ECU, which is going to void your warranty if something happens with your engine. |

As of stolen soft - I am not the legal expert but I must disagree with you. Why would you call it's stollen if its not even commercial product. I mean BMW does not sell 328 software which you can buy and reflash an ECU. These guys don't sell it ether they install BMW 328 soft to 320 BMW car, and charge for the labor and know how. As an example: when someone modify original N54 software and chip his ECU would you call it stolen/hacked ? |

It is funny. When i read this thread i keep thinking about russian tech heads in the james bond golden eye movie who said "western software crap" and hack into western systems like child's play :-p
I wonder if there is also a hot "natalia" behind the software :-p In the end, a modded 320i is only mildly quicker than a stock 328i, which is what is suspected would happen and why i coughed up a bit more for the 328i.

That is unbelievable! if this info is true, BMW has a lot of balls distinguishing its models based off of software. I won't be surprised if they eliminate the n20 engine from the 320 in the near future. iam so going to check into this further. everything is pirated now a days. its easy to reinstall an entire ecu map if you have the know hows & if you have the original software (which we all do). that's what my last car had. I changed all major components on my stock hemi engine and pretty much fooled it into thinking it was an srt engine. it worked like a charm but it took me almost 8 months to really get the engine dialed into the new ecu parameters. you have to really monitor and know what your doing. if someone can somehow translate this, they would probably be driving a ferrari as there daily car and a bmw as there winter beater!
i wouldn't even want the jb4 to be honest...it wouldn't be worth the money if I could make 240 hp at the wheel. the stage 1 costs 400 and the stage 2 costs another 150. is 20whp worth $550? hell no. plus you wouldn't make anymore power on pump fuel. The stage 2 cant even do it now unless using e85 mixture. to me stage 2 is useless unless you want to data log and play with parameters. and that thing has a higher chance of voiding your warranty. You got to connect and semi splice into your factory wiring harness! what were they thinking?!? the stage 2 reminds me of Sega CD. The genesis was great until they brought out the life support system. they should have redesigned there tune. just an opinion. I still love my bms 1. |

Now there are many members who reflashed their ECU's and posted reiews, racing videos e.t.c. Last week I was given a ride on 320i reflashed to 328. Now I am 100% sure it's possible The guy who reflashed his 320 has BMS ST2 as well, after reflas he connected it and looked at logs - according to him reflashed 320 - has a lower boost than 328- probably to compensate for different compression ratio. Intresting thing is that if you have less that 50 hours of work on your engine - the reflash could be done without physical opening the ECU |

It's STUPID.
The 328 software is engineered as such, to match the car and all its hardware and fuel trims, boost targets etc. The 320 is not the same, largely due to the compression ratio. So just loading up 328 software to a 320 is a hack job. At least with BMS they watched all the information from the sensors and had safety in mind when they tuned the 320 SPECIFICALLY. I am sure there is safety margins and you can get along fine with a 320 left stock on the 328 software and used the highest grade fuel. But for $349-500 you could just buy the BMS tune and make more power and know it was done with the 320 in mind. When spending money on a new BMW, when a few hundred on a tune is turned down over a software hackjob, your money priorities are a bit F-ed. Lately it seems like most N20 tuning threads devolve into this Russian software hack crap. Put it in it's own thread instead of muddying up the rest of 'em.

at least, now, it seems like you believe reflash is possible Jamesons, without taking into consideration that the reflas was done by Russian tuners - could you please explain in technical terms why BMStune ( which does not have full control on solenoid, and many other parameters and still in Beta testing) is better than BMW software that has full control on every sensor and was designed for ALMOST the same engine. btw I am not promoting Reflushers )) I am deciding how to tune my 320i , the way will be the best for the engine |

It's different because BMS bought a 335, 328, and 320 and monitored all variables to each specific car and tuned accordingly. What you are talking about is taking BMWs specific software for the 328 with no changes and blindly applying it to the 320 when it is a known fact that the two engines are not identical. I do not care what people do, make your own decisions. But it's been prevalent for weeks now that in this forum about engine tuning, it digresses into this scenario of "In Russia we OEM tune 320's with 328's..." Either way... 1) Something not done in the US which is what 90% of this forum concerns themselves with 2) Voids the warranty-which is what the aftermarket tunes do anyway-so where's the benefit? 3) Not something that is specific to the 320 N20, a compromised plan from the start I said my peace. Carry on.
