Absolutely pointless. MBCs are for people who provably can't tune N75 properly.

Gotcha. I definitely have a loooooooot of reading and trials ahead.

Sorry to ask but was the stage 2 xdf ever shared in this thread?

I have the stage1 xdf and the full mbox xdf, but honestly there is such a huge difference between the 2. The stage1 xdf is awesome, the full mbox xdf is thoroughly confusing.

Any chance someone can point me to stage 2 xdf for mbox?

There are not multiple xdfs, dude.

If you have a fully defined .xdf, then you basically have stage X
(X=insert arbitrary number here).

As in fully defined; you have all maps at you disposal.

Kasper, I'm aware of that. My question was, is there an in between of the 2, but apparently not.
The stage1 xdf that daz had left us was nice and simple, maybe too simple? The full xdf has an overwhelming amount of maps/tables in it, with so many obscure ones.

Perhaps I got spoiled by tactrix/romraider for subaru where the xdf tables are very defined and clear. And I always had daz help me with my S4 bins and never had much time to learn me7 until now. Anyways, motor on!

After the start with the bare bones Stage 1 XDF we just used the full XDF, so there is no Stage 2 XDF.

I did try to summarize the changes in the Stage 2 tune and mention what the table did along with giving the name.

The summary is here -> http://www.myaudis4.com/stage-2/.

This.. sorry about the confusion. The "stage 1 xdf" is just a "noob" version of the full xdf.

Just use the full xdf.

Here is how I view logs for timing work:

If the camshaft angle is 0, that means KFZW is being used. If it is 22, that means we're in KFZW2.

In this log, we can see that from 3800 onward the values in KFZW are being used. Prior to that, it is KFZW2.

We can also see two knock events. One at 2200rpm, 150ish load. One at 2500, 160ish load. Take a look at the values for in KFZW where 2500rpm and 150 load intersect. Reduce timing in that area. NOTE! Just because CF is 3, does not mean you have to pull 3 degrees! One knock event at that RPM means CF's will be 3. This is actually not bad, and can be left as is, but I wanted to post for illustration purposes.

I would then suggest making sure KFZW/KFZW2 have the same values around 140-160 load at 3500-4000rpm to reduce the notch in timing. After that, relog. If you are not showing any CF's, I would then suggest adding more timing up top, from 4500 onward (to KFZW).

I have another Question about KFZW and KFZW2:
Are the values in the table the angle of the Crankshaft when the Ignition is initiated ?

It is either BTDC or ATDC(-) and 0 is TDC

I wanted to flash this to a 2000 A6 but I have a bosch MAF so I edited the file. The only changes were for the MAF

I've got a near stock 2000 S4 6MT with OEM Bosch MAF. I've flashed another 551A bin but this would be my first attempt at flashing a 551M bin. Running Verify Checksums in Nefmoto hung the program, so I ran me7check on camlacen's above bin but received the following errors:

me7check v1.12 (c) mki, 06/2004-05/2012

-> Contents of ECUID data table:
- 'HW_MAN004'

Page checksum failure(s) found
Data area checksum failure(s) found
-> Found 4 errors!!! *******************************

Should I try to fix these errors using me7sum (it would be my first use of that software), or is there another issue?

Done. Attached are two Nef Stage 1 bins adjusted for Bosch MAF, with the second being optionally adjusted to avoid a nuisance communications DTC on non-CAN-bus cars (such as my 03/2000 build date S4 6MT). I've briefly tested both with no unexpected issues, but have yet to do logging (and one of my recently replaced exhaust flex couplings just let go on my way to get stickered, so it might be a while).
