Sup all,
Chasing advice and info about changing/flashing another tune on my ecu.

The car: 2002 a4 b6 quattro (AVJ 150hp model)

Current mods:
-3 inch decat, followed by 2.5 exhaust
-K04-015 turbo (recently replaced the stock K03S)
-R8 coil packs
-Stg 2 clutch
-upgraded diverter valve, TIP, crank breather
-Running SSP stg 2 tune for stock injectors and turbo, spiking at 22psi.
This ecu is out of a similar American AMB 02 a4 b6 and works because the immo, SAI pump and 02 sensors are deleted. I only get 1 engine light for the evap pump (because my euro model didnt come out with one)

I have been running my k04 with a manual boost controller (set to limit boost) and the n75 valve.
This did not work well so ive just ditch the controller and used the n75.

Now the boost surges and i hit 1.5 bar on 3/4 throttle  :o 

My plan was to use the k04 with the 440cc injectors I have (which is fairly common apparently) I have been trying to get a tune locally and various tuning companies overseas like Motoza without any luck. No foreign companies are interested. I will mention the one local tuning business that said they could do it for $1400.

My questions:
-Can I edit the tuned ecu myself so I can use my 42lb injectors and K04 turbo? (Im completely new to ecu flashing)
-If it isnt possible to edit, where can I get/buy this special tune file to flash on my ecu?

Anyone with a Audi B6 1.8t K04 tune that could add to this? Any help would be greatly appreciated cheers  :)









 
 

Youd be beyter off making a new file anything more then 1 bar to redline and the cars out of fuel on stock injectors or at least leaning and not making request. Tuning off evap is a simple bit switch.

Thanks, yeah I am definitely running lean so im just staying out of boost as much as i can. Im currently reading various how-to guides but I doubt ill be able to simply make a new file.

Its really not as hard as youd expect. Tooners want you to think its hard to make a proper file because 8t makes tjem worth somthing but in reality youll find that they dont know much. 8ts like 10-12 maps youd need to adjust for a OK file for your setup not including  emissions maps

Well let be helpful aswell, you sir are in luck there is a thread on this forum about tuning your car.
In that thread there will be a base file and alot of modified files most of those will be very close to
what you have now, there is also complete instructions and mappacks in that thread. Literally all of
the hard work has been done by those that came before you and shared for free out of the kindness
of their hearts (Except PRJ) he shares because he likes to prove he is the best (which he is). ;D

I've been looking for this thread you speak of. So far I've found this:

http://nefariousmotorsports.com/forum/index.php?topic=5621.0

It is for 440cc Bosch injectors like mine but for the stock turbo. No idea if this will work on my car. I will probably need to edit it so I can delete the evap pump and change the compressor map. Does anyone know if I can flash this and use it on my 5sp manual Quattro B6? I have the ecu soft coding on my donor AMB 6 speed ecu changed to suit my car and it works fine. The ecu I have is also 'AK'

Spend more time looking for threads, try to use google because boardsearch is crap

Man when we have to give them links, i almost feel we should just write the tune.

 ;D links save lives, thanks

Any opinion on buying this and flashing it?

http://www.ebay.com.au/itm/02-05-Audi-A4-B6-1-8T-8E0909518AK-K04-Stage-3-ECU-Tune-95HP-NO-CAT-NO-IMMO/122552162600?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2060353.m1438.l2649

Or i could use nefmoto flasher to put the stg1 tune (made by Blkserialkilla) on. Other than the fact this tune is for the stock k03S, is there any reason why it wont work just choosing it in the flashing tab and selecting 800bb memory layout? It cant possibly make the car run more lean than it already is.

Just do some in depth reading and get a good understanding of everything in the Wiki... It's not an overnight thing, but at least then you won't have a melted engine (unless you cock it up by rushing into it without an understanding) and you'll make decent power.

The k04-015 btw is barely larger than the k03s, I would think you'd be just fine on the k03s tune boost wise. Injectors only need a few things changing... All of which is in the Wiki.

Do whatever you like man, it's your car so it's your decision.
But if you don't want to put in the time to learn to do it yourself.
Then pay a local tuner, and let him make a proper tune for it.
But I strongly advise against a eBay tune.

WAT HE SIAD. ^^ THIS ISNT THAT HARD AND YOU HAVE A GOOD COMMUNITY SUPPORT AND A FEW GOOD THREADS TO START WITH. If you have any questions feel free to ask. Id be happy to help

Alright thanks ebay tune is no good. I only looked at it as i have few (essentially no) local options.
Cheapest tune i am aware of is $750 and thats not local (other side of Aus). As for trying to edit a tune
myself and getting it to work perfect... Id have more chance of landing a triple back-flip. Haven't given up
though. I have been reading the s4 tuning wiki and this:

http://nefariousmotorsports.com/forum/index.php?topic=6955.0title=

I have been looking at different xdf and ecu.bin files on tunerpro and trying to follow
the community 1.8t project. No idea when i will actually understand what im doing.

Blkserialkillers tune for 440cc injectors looks promising if i can figure out how to edit the
boost. K03S and K04 are similar but still i get way too much boost after swapping
them. The attached file is the tune im referring to. Should i use this as a start or read the
ecu tune im currently running and use it?

Krkte and tvub maps to get injectors scaled. Use block 32 to dial them in on vcds. Dialed in by adjusting krkte value +/- based off adaption. Use good brand injectors and be sure to put the voltage times into tvub that came with the injectors. Injectors dont have the same dead times between sizes or brands sobe sure youre using the right ones . Start with the group-in 518ak, read what changes are made and try to u derstand why

Some are not going to like this fix for your boost and YES it is a hack BUT it will work and keep your boost spike down until you learn how to log and make changes to dial in pid control. Work on fueling with larger injectors and get that set first before you try to get boost set with just the n75

No.. Do NOT do any tuning with broken hardware.

Period.

It is a complete waste of time. You're "saving" time by working on something you'll only have to retune later.

whats broken? did i miss something? 

Sorry got this confused with the boost spike thread.

In any case, i'd just start with a much more conservative IMX to limit boost while dialing in fueling (if the hw is fine).

I agree with lowering imx but considering his boost issue and lack of fueling i feel for now his easiest option is to 7se a manual boost c9btroller

Sorry my phone is a pile of shit

Pulling IMX takes 30 seconds, plumbing a MBC in parallel... a ton of time, then you have to undo it and start all over again anyway

Just my opinion, YMMV

But if he started with a tune with less boost like the stage one here.
Then he could throw some 550cc injectors in and be really close after
a couple tweaks.

I can't do a full read flash of my tuned ecu or my original. I have done everything the forums say and have researched the problem. The memory layout I choose is  ME7 29F800BB.MemoryLayout.xml. I have the battery charging while doing reading it. The Baud rate is lowered. I see people say you cant read some tuned ecus, ok but why doesnt the original work?

I should work with my own original tune rather than someone else's tune which is why im trying to read it.

What we mean by YOUR tune is obe you make. The reasons why you make your own file is so you know what changes have been and why. Lean how to log, how to read the log and how to make changes to your file based off the log. The file tjsts on your eci is not gold and i bet its not even that good of a file. Ive recently retuned some of the files made by your current tuner and i can say they really are junk. My point is spend your efforts readimg amd understanding efi to start and how to make a file for your car on tour own or use the group in project as a base.
Youre not going to read the pile (i mean file) without removing it from ypur car and bootmode read. Tooners will F0 >FF the bootrom or add "noread" tags in the file to stop the read. Any good brand tool respects noread tags threw port flash

Thanks, I have known about using the n75 and mbc to limit boost for ages. I am running the setup that you sent a pic of right now.
It works but the boost surges and is not as good as when I had the old turbo and just the n75... makes sense

Trying to move away from stock injectors and the mbc.

I agree, my current tune is worthless now that I have different hardware. I have 2 ecus I can work with, just which one to edit is the question (stock or tuned)
Nefmoto flasher wont let me do a full read flash of either -This doesn't matter because i can just flash the new tune over it, I understand.

Since i cant read my own file and edit it i will need to get another file to work with. The stg 1 tune for 440cc injectors which i keep talking about is what I was thinking of using but nobody has said "yes" or "no"

Where you want to start is your choice. Youre asking for input well heres my 2€. Use the group in file as a base and tune for larger injectors. Lower imx as Nye said and start from there. Not all 518ak files are the same i think 4 versions? So not all of the maps line up with other versions and you wont be able to use missmatch map pack / files. The main reason im saying to start with the group-in rom is it comes with the right map pack for the file. If you want to use 440cc injectors you can port tvub from the 440 file and calc krkre.

Thanks. Im getting there.. Slowly :') Im using the stock AMB ecu file  (8E0909518AK_368072_NEF_STG_1_Stock.bin) and comparing it to the 440cc stg 1 file because I have no idea what the values should be. When you say port tvub i guess you mean copy over the injection time offset from the 440 file. I still dont see why I cant copy both tvub and krkre values over but maybe i just havent read enough on s4 tuning wiki. I thought of flashing the stage 1 440 file straight over my tuned ecu and then logging it with me7logger (which i currently cant do because i dont have my .bin file) so all i will have to do then is adjust IMX according to logs.

TVUB can be copied if you know for a fact the injectors are the same.

KRKTE most likely needs massaging anyway.

Apparently its safer flashing me7.5 ecu's in boot mode so im going to try and make a bench flash harness. Ill have to find an ecu harness/connector and a female obd2 connector somewhere first. Just following this:
http://www.audizine.com/forum/showthread.php/445065-how-to-build-a-bench-flash-boot-mode-harness-for-your-me7-ecu

I read somewhere if you fail to flash the ecu via obd2 using nefmoto flasher you will brick the ecu. If i cant full read flash either of my ecus with nefmoto flasher then the chances i can flash a new file over using it are slim. Next attempt will be boot mode + galletto

Also I am planning on buying bosch 550 ev14s since i can get them pretty cheap and the 440's i bought (unwisely) are not genuine.

Not sure where you read that but it's not really true.  I had a stock R32 that wouldn't read, but would write fine.

Hey a see this is taking a good turn. 550s and new cable

Start from scratch.  Set or verify IMMO is off.  Write the software version you intend to work with in boot mode + galletto.  At that point you shouldn't have any issues flashing with nefmoto.  You'll need to power up an additional pin for me7.5 (forget which one off hand) for bench flashing with nefmoto; I did not need to do that for the 95040 tool or galletto.

If you don't start from scratch, you'll never get it IMO.  What I've learned, is that the pieces of the puzzle are all available (s4tuning wiki is a huge piece) but it's up the the individual to put them together.

I've stuck with the 0003 version from the community stage 1 thread and have built up the definition file from referencing a couple of fully defined 0004 def's.
