MAF off the throttle is because somebody deleted N249 valve.

Put it back in.

What I'm worried about is that my turbo lasts too long to spool until desired boost pressure. It can reach desired boost only in around 3500 rpm... Too late. :/

It does seem a bit slow. Perhaps you have an intake restriction? It is common to have inlet hoses collapse.

Hmm I wonder if I could use my n249 for dv purposes ? Its used for intake tract changeover by default, what do you think ? its a 3am idea dont bash me Cheesy

like telling it to open at x rpm and 0% pedal but then again I dont know the axes in na soft .

Can anyone who owns a BEX/BFB/ANB tell me if these small k03 longitudinal tend to glow in stock and stage1 condition?

Yep, especially if the kat is there Smiley but should only glow after spirited runs

So I've been following everything for about a week. I've tried doing things on my own (got tuner pro, been digging for XDF files, etc...) but I'm hitting a wall. I didn't wanna give in and use the community BIN. That being said, I have an 8E0909518AF ECU with 0002 software. I don't wanna flash your bin, but i did want to pull it and use beyond compare and move some things over and test it out. Are there any major differences between software versions 0002 and 0003? Thanks again for the great work everyone. This is all really cool stuff, and something I've been interested in for a very long time!

Well, looks like other people have changed SW versions without much issue, and if I can't drive the car, I've got a working stock tune to flash back to, so here goes nothing! So I was looking over the community bin and noticed that PSI peaks around 14psi, then tapers back down to 7ish. This is because we're getting pretty high in IDC. There are tuners out there selling "Stg1 tunes" that are making 18psi and claiming like 30-40hp over stock. I wanna dig into this, because I wonder if they're dialing back timing to prevent detonation to run a bit leaner than we may consider safe, or if there are other values we can look into as far as fueling is concerned (and I'm about page 20 of the thread, and maybe I'll get flamed for this, idk) but I'm also wondering if anyone has an off the shelf tune that they can log for us, so we can see what kind of results the big guys are seeing as far as boost taper, peak boost, timing retard and injector IDC. I hope this wakes this thread back up because it's VERY exciting!!! Cheers!

Given the fact that we don't have the appropriate RAM locations to log, I think this is a fine idea to help narrow things down.
I see this thread has been dead for quite some time now, just wondering if anyone was able to successfully locate the RAM locations needed to log the torque intervention variables.

I think KFLBTS is wrong in this xdf. Bassicly im making mappack with winols, studying this software and i found some errors. In my opinnion it should look like that
Start adress 198EF 8 bit 16x12, rpm columns 16 from adress 199B0 offset 40,000000, load rows  12 from adress 199FF offset 0,750000 both axes and map are 8 bit.
I dunno how to correct xdf, but will post more mistakes.

Odd offsets are suspect. Most maps should be 16-bit aligned (even addresses, not odd)

I should say factors, not offset, my bad.

No, i understand.

The issue is the *offsets are odd numbered*. this has nothing to do with factors. 198EF and 199FF are odd. Not odd strange. Odd, not even.

I can't stress this enough. You MUST understand what that means, period.

In ME 1.5.5 damos load axis adress is also odd, you think damos might be wrong?

Why the calculator? F1 is odd. F0 is even.

not sure about ancient versions of ME.

There is an alternative "tylerW" .xdf file for the for the 8E0909518AK-0003 ECU in addition to the 8E0909518AK_368072_NEF_STG_1v7.xdf that was developed within this thread. The tylerW xdf can be found over in the rather short stage1+ thread;
http://nefariousmotorsports.com/forum/index.php?topic=15799.0

I checked and verified that the tylerW dxf had KFLBTS located at the same 198EF location that you have identified.

As a nooby at this myself, slowly trying to understand this entire long thread and using the included xdf to sort through the many .bin changes, my feedback is that the 8E0909518AK_368072_NEF_STG_1v7.xdf from this thread is perhaps not actually the best available xdf to use. The identification and function of the numerically labeled "parameter category" folders that are visible for this xdf within tunerpro do nothing to help find or explain the purpose the scalars or table groups and the documentation available in the individual "parameter comments" is minimal.
 I am finding that the tylerW xdf is more helpful to me for understanding the .bin files within tunerpro as the tables are all categorized with more easily recognizable and useful parameter category labels and the parameter comments entries are more complete. Many of the parameter comment descriptions are included in both the original German and with English translation so I would presume that this xdf might have it origins as some sort of original Bosch map definition?

One potential criticism that I can see for the tylerW xdf for nooby use in this thread is that it has more additional tables identified than might be strictly needed for the stage 1 tune but I find the additional organization and documentation outweighs that con.   

This entire thread has been tremendously helpful for getting me started with ECU tuning for my '03 A4, many thanks to all the contributors over the years.

I had a look at you files and tried to emulate them with my ecu which is a hj, it started very well.
It was overboosting and then reducing down to 10psi, and then stopped. I have this code on my ecu 01314 -  Engine Control Module        004 -  No Signal/Communication I can connect to other modules but not the ecm?

Can ecu's brick themselves while running?
I cannot connect through the obd to the ecu to reflash.
