https://s4wiki.com/wiki/Tuning#DTC_disables

You need to be more specific, you'll get the dtc's with no parts on it, sort them as per wiki/numerous threads, sort eskonf - done. You are using a definition file right?

Yes, using one from here http://nefariousmotorsports.com/forum/index.php?action=dlattach;topic=491.0;attach=522
and here http://nefariousmotorsports.com/forum/index.php?action=dlattach;topic=491.0;attach=509

Shall go through the s4wiki link, thanks I didn't see that particular page.

Still very new to WinOLS & TunerPro, so youtubed it.
Found out there's me7eskonf https://www.youtube.com/watch?v=0z9U8JBFlH8

Can't find it here though. Is there a trusted source for DL, or even a github available?

You don't need it. Find KFKHFM (easy map) few places before that in hex is your ESKONF. Should be able to recognize it.

You have too much faith in me knowing what I should look for!
Using the 8D0-551L from s4wiki files & xdf from the previous post in WinOLS.
When I drag xdf brings up weblink for plugins, as using demo version.

Tried using Turboman's vid https://www.youtube.com/watch?v=0dkuoFh2foQ&t=81s
but have no refence to match it to.
I really am a FNG to all this.

Also thought ME7.1 for my 4b0-551G ecu with 8d0-551L map. Would they look the same?

https://s4wiki.com/wiki/Tuning#ME7.1_bit_pairs

From my own ME7.5 "knowledge". See what is installed and what is not. Calculate using binary > hex this should give you a pattern to look for. Atleast that's how I would go about it. And we know it is before KFKHFM, so i believe this method to be quite bullet-proof.

Though i'm not sure if XX would be 10 or 11 but you'll find out fast enough. If you look for it you'll also find ME7ESKONF on here, i must have it somewhere on my PC.

No- that address doesn't match with your 2.7T ME7.1. It comes from my own ME7.5 1.8T. Your ESKONF is twice as large.

Read wiki and it will start to make sense.

Thank you Sandstorm3k for the pointers. I'm learning slowly but surely.

Not sure how to contact s4wiki admin/mods, but https://s4wiki.com/wiki/Tuning#ME7.1_bit_pairs
is missing Byte 9 for ME7.1

Also anyone know what the "ZUE: Ignition coil" refers to?
Original 3 pin coils with coil packs thingies on top of airbox (for 2.7t's)
or the 'RS6' coils or whatever people call them, with modded loom and 4 wire coils.

with my decoding of the Hex (Technically Theka Hexidecimal  [10+6 decimal, not 6 decimal!!]) shows EV2 & EV4 'not installed' which is ONE HELL of a coincidence since I have had misfires from those two cylinders.

Obviously no rush in responding as running original 4B0-551G ECU, but hope to switch over to 8D0-551L without any DTC's.

Cheers

Its a wiki; you can edit it yourself. Are you familiar with wikipedia?

Anyway, that looks like a typo. Also ME7.1 only has 6 cyl, not 8, so probably its doubly wrong.

Quite literally, the output pins of the ECU that correspond to the spark plugs.

ESKONF merely represents what outputs are enabled on the ECU.

Totally irrelevant.

no idea what you're saying here. if ESKONF is wrong for EV2/EV4 your car would not start.

Not done S4's but eskonf unsurprisingly looks same/similar to 7.1.1.'s, usually around the 010xxx mark at quick look, printed off a csv if it's same/similar/cross flashing etc - it's 1a.m. I'm sure you can figure it out!

Yes I am, but I would hate it if someone put wrong infomation in place of an omission. Also meant to be 13 bytes for 2.7s,only shows 12.

Anyway, that looks like a typo. Also ME7.1 only has 6 cyl, not 8, so probably its doubly wrong.

What I'm saying is: some idiot decided to re-invent the Greek language. 'Hexadecimal' is meant to refer to 16, not 6.
As I am 3/4 Greek, it is the equivalent of someone from a different county deciding to leave off the 'teen' in sixteen.
Hence Hexadecimal should be corrected to 'Theka Hexadecimal'.
A pet peeve.



Anyway, the ESKONF is "13 bytes in the 2.7 flash"...

    10 = SPECIAL TREATMENT. For all intents and purposes, we're going to ignore this.

I think they're calibration files in that last link so it may not be 100% accurate, but you'll find a set of values similar around that area in yours if not the same. You're on the right track though!
