Your car will blow the fuck up if you turbo it or try to tune it! N/A is best!!! I take responsibility for nothing. All info is owned by someone else! Probably Jesus! Feel free to copy and paste my info and links ANYWHERE and feel free to make money off this! I don't care I want to help! Rick P. is a ****!

Good luck, and when you see this ^^ you know you need to crank up the boost to blow the chunks out the 5" DP.

So RHMT is > HMT. I get really tired of people thinking having the tools to tune a car = being a tuner. I am also tired of lame asses acting like they are god's gift to man for having their boyfriend or parents buy them a tune, or hold their hand and click the mouse for them.

I lost my old harddrive with all of my programs from megasquirt stuff to honda stuff to bmw programs, but this is plenty enough for someone to make a basemap, or even a solid baseline tune. I will continue to add tid bits here and there.

Ok some background stuff:

A collection of BMW .bin files that I still had left... lost a few "pro" rips I had, will up when I get a chance... better yet, someone PM me and I can send them to you and you can host them/deal with the legal consequences if there are any. I divided them into 403nv and 413vanos rar files for now. I will update and add many more but for now those are STOCK bins.

http://uploading.com/files/9WR8MW76/413Bins.rar.html 413

Ok now you have tuner pro, a chip burner or ostrich (hardware available from xenocron.com).
Now you need to make a definition file. I will update one soon to add injector offset and a few other little things to make driveability and PT better.
Here is a collection of .xdf's from around the world wide fail. I also included links to MapHunter and Analyze for hex savvy people to use and contribute if they so choose.

The referred to injector latency constant that DRAMATICALLY helps PT http://www.bimmerforums.co.uk/forum/...latency-t1443/

Ok some more info for tuning non vanos: The MAFs hit the voltage limit relatively early and there FEW other options so you have to mess with the stock MAF. Here are some ideas I discussed with a very cool guy from Romania. "regarding the MAF issue - a method that works very well it was this one: remove the 325MAF element from original plastic tube , put that one in a aluminum or stainless 90mm diameter tube + a 800ohm resistor on MAF signal return wire (in my car that wire is blue, but you should search for your MAF wiring diagram, because is different than the wiring used in 402/403 configuration ...) - in this configuration, even at 14psi, that MAF will not be maxed out. Mention that you will experience some low-load issues, as 200-300rpm idle variation, slow throttle response at low loads ...
another solution is to install a resistor on your original MAF signal return wire (i can't tell you how big should be this one, but bigger that 400ohm - i tried with this one , and it seems that is not working well , even at 12-13psi, at 5000rpm the MAF is maxed out ...)
anyway, using a big resistor you should think about the fact that you are diminishing the range of your MAF (probably after 4000-4500rpm the MAF will start to indicate the same value ...) in this situation you will need to manually increase the fuel for the top of the rev range ... and if you will be on that rpm range without full boost (part throttle), the mixture will be very rich ..." - Bogdan
The idea here is to increase the Diameter of the MAF tube if necessary and by adding a resistor you essentially "bump up" where the maf table begins to read the load. You are losing resolution and low end response but there are not many options. I suggested using a zehner diode to limit the voltage to say 4.7volts and/or adding a resistor. I recommend for both vanos and non vanos cars locking the MAF at max voltage of ~4.7.
For the 413 vanos cars you have a ton of options of bigger and better maps that will read well over 500whp. I personally believe that using the 413 DME, proper injectors and MAF can yield 700whp or better. Stock MAF should be good to 300whp with minor adjustments, maybe more depending on how you play with it. Same resistor tricks can apply, also changing the MAF tables. The included XDF's have tables for stock 403/413 MAFs, resistored MAFs, 540 MAF and the porsche 803 MAF that can take you over 500whp.

Here is a GREAT collection of threads and documentation AND a FANTASTIC corrected MAF table .xls... you NEED to get this.
http://uploading.com/files/NXCBDDKT/Docs.rar.html

Also, a thread about making a <5$ multitune for the DME, I personally uses this as a theft deterent .
http://forums.bimmerforums.com/forum....php?t=1176730
Also! If you have an EWS enabled 413 or 506 DME (M50 and S50 can interchange bins, and DMEs!) in order to use non EWS bins and tunes you will need to kill your EWS. To do this, use a non EWS tune and snip pin #66 at your DME, alternatively snip pin #7 at the ODB connector, although I always cut it at the DME. It is probably a thicker green wire. But pin 66 is the one you gotta kill.

UPDATE 10/31/09

There has been a lot of development in this field by minds greater than mine, with more free time than I. The Tunerpro website now features definitions which are A LOT more complete than previously posted by me and the new beta of TP features data tracing or something of the sort so you suckas are ready to tune a lot better than a year ago.

Really this should be enough to get anyone on the road. I will add more as it is convenient for me, or as is requested by non failures. Thanks.
Also if you think you might be of use of me, or want to buy something from me, suckblowboost@googlemail.com is the addy. Pictures of your female relatives are also desired. Also, this is was written by me, and posted on multiple forums for ANYONE TO REPOST SO NOBODY CAN PURSUE LEGAL RAPE OF YOU FOR COPYPASTAING THIS. EVERYONE CAN HAVE THIS INFO. SUE HAPPY ASSHOLES; KEEP A COPY UNDER YOU PILLOW.

5 star that shit for an HMT brotha and lets get this 413 DME more hooked up and pimped out than a p75

cool but i dont have a bmw and not into european fail building

BoostedSchemes · « **Reply #2 on:** March 08, 2009, 07:34:37 AM »

the nice thing about bmws is that there is no fail building involved if your looking for <500whp
stout fucking motors
just dont be me and run an obscene amount of timing because you dont understand the fact that timing in upper cam profile uses different numbers from lower and end up running 30* of advance at 30psi on a 4th gear highway ripper and listen to what appears to be a truckful of newspapers being jammed into your intake (lovely det)

30 degrees of timing at 30 psi sounds insane diffeent motor wants a different timing curve but that seems a bit hi. less than 10 degress sounds like a bunch for a honda even!!

Nice, there don't seem to be many BMW people that can do more than change their wiper blades, much less tune their own car. I'm hoping to get a rwd as my next project car (67 bird not included), so its either S2k, BMW, or Nissan. Small & overpriced, big & overpriced, or old & overpriced.

BoostedSchemes · « **Reply #5 on:** March 10, 2009, 01:34:53 PM »

Find an early 90's 325i coup
RWD, I6 good for 500whp, LSD
If its beat enough, you can find them on CL all day long for 1500$ or less.

That's about what a SBC-II with a ~1000whp turbo and good flowing gear bolted to it likes to run.

HiProfile · « **Reply #7 on:** March 11, 2009, 03:53:38 AM »

It also has a 20% wider bore. M50's are like any other motor, they don't like peak cyl pressure at 8* before tdc...

Joseph Davis · « **Reply #8 on:** March 11, 2009, 09:31:58 AM »

I wasn't saying it was good timing to run on the M50tu, I just said it was valid timing for some engine package out there. Mr Tangent here, ok.

food for thought: if you can log in any way from your knock sensors (try tapping the wire at the DME, or get fancy otherwise) if you are in anyway picking up det on your sensors the stock dme will seriously fuck with your tune. disabling the adaptation, I am told, can help but I really like the feature so I will have to play more once I get my new pistons/rods in

reason I mention this is that I had to dramatically swing timing one way or the other every time I would retune, even at low throttle cruise... someone on bimmerforums pointed out that once it pulls timing from seeing det, then adds fuel/pulls it from its adaptation you won't be able to ... tune your tune... until you remove the dme from the car. changing the bin does not clear the adaptations.

A certain hairless freak has helped me out with some winOLS loving, a lot of people say its useless trash but I will see if it can help me out some more. not gonna make ANY progress until my car is on the road again and I get a job though.

Update, there is 404 DME definitions starting to circulate. You niggas know you love that v8 E34 boosted shit.

you suck at tuning

what happen to that WAR chip thing, wasent that supposed to me $350 tuning package? i got another 325i + holset waiting for me to do somthin about it

It was an invite-only link to the TunerPro 5 download, sorry. It should be released in another month or two.

Not so long ago I had it... didn't know you didnt. Would have gladly passed it on, you know im on tp's dick.

No, I had it. Reason #1 why I didn't hand it out; some bridges you don't want to burn.

im gona wait to see how this shit pans out before i try to learn all this tunerpro shit, this looks more like somthing i could figure out

I have tuned BMW and VW OBD1 cars yes. I did a 93 318 with a GT28rs and 42# injectors and a VW 2l with T3 and 42# injectors. They are both alive and well as far as I know.
