Ecu tuning

Sorry if the post is not in the right section, i'm from Qc, Canada and I'm not as good as all you guys/girls in english...So Hi I have a 328I 1999 e46 and I already know that their is many many thread about this but i'm don't understand and I don't find what I am searching for(even with two full night of intensive search)
Here's my ''problem'':

I would like to turbo my 2.8, and I know that I need gasket and arp studs, after that I would like to build-up a littile setup(i'm gonna see later what a REALLY want but I have a good idea by-now) by the way I am going to school in mechanic and I already have a good base on it, but when it comes to ECU tuning....i'm lost.... I'm running a obd2 ecu and that's pretty all I know... I found info about kwp 2000plus, MS2, AEM EMS, but I don't know where I need to go with all that...every kind of help would be really appreciated... btw I would like to keep all the luxury/comfort things I have, such as mem leather seats, control on the steering, etc. Thank you

Do yourself and your car a favour and let it set up! even with a really good damos file, you won´t be able to set it up properly.

In order to keep all your dash functions and wheel functions you are going to need to use a piggyback, personally a piggyback is a poor solution for a turbo in a BMW application. I have done what you are talking about search my name in the forced induction forum I have an extensive build thread that will give you lots of info. If you have any questions feel free to p.m. Me

Also I have a clutch master clutch stage 3 Kevlar segmented with light weight flywheel all from clutch masters, has less than 6000 miles on it and looks perfect, it would work great for what your doing, I bought t brand new for 1600 I will sell it to u for 500 plus shipping if ya want.

Probably this statement.

It's not difficult, just do the research and get the right tools.

i consider myself pretty knowledgable on EFI tuning; i did a lot of street tuning on my previous acura rsx (k-pro FTW). but, when it comes to extracting more power and improving throttle response, ignition set points, etc.......on a bmw, i like to trust the guys that have tons of experience to tune my cars (eurocharged, or others for the e90/e82 cars)

That's so funny... small world. I'm actually Hondata's biggest competitor.

WinOLS. You'll need to use some other tool to flash, like kwp2000+.

Piggybacks do not work well on BMW e46 platform, I have tried them all either they run but very poor and then the BMW goes into limp mode, or the dme re flashes itself after a day or so back to stock.

You can get a piggy back or full standalone, but it's not necessary.

Megasquirt is very basic but it will work.

I mean megasquirt is limited in table views when tuning, also it only controls a few basic functions. It is a very basic program, bt as stated it will get your car running, but it won't control vanos which is a big help on our turbo cars.

This is a loaded response by you, okay you are technically right ms can run single vanos in a on off type of setting which anyone that know anything about vanos or variable timing knows in a on off situation it takes ms a second or so to go from on to off or vice versa! so to sum up to properly and beneficially run vanos on a turbo car you need a more advanced stand alone that can process the variable timing or vanos in real time.
