Title: FIRST POST HERE ! Question regarding a Octavia RS 1.8t Stock vs ABT tune....
Post by: ngt84 on April 06, 2021, 04:41:14 PM
Hello ! This is my first message i think....
After many years of guys harassing me to start to tuning the "nefarious" german 1.8t 20v engine... I bought some tools
A friend came over he just bought a used 2004 Skoda Octavia 1.8t RS 180ps and it has an ABT tune (as the ABT stickers and psychotic service manual of the previous owner suggest)
This car allegedly outputs 210ps now on the dyno. There is a dyno sheet in the glove box.... Also this car has two error codes appearing once every week or so (EGR and boost valve)

-So i read this cars ECU and its tuned file, with KESS after switching on and off the key numerous times as per the kess instructions i got a 1024kb file....
-ECU INFO HW: 0261207440 SW: 1037363908  Engine: 1.8L R4/5VT SW upg.: 06A906032HN 0002 CHASSIS: 1U5 5MT MOTOR: AUQ 180PS
- Wouldn't open with winols so i had to edit out the NOREAD injected text with another binary editing program.
- Downloaded a DAMOS file, wouldnt open with demo winols from their website, had to download an illegal old one i guess....
- So i compare a stock file and the ABT tuned file and the differences are....
1) KFMIRL is changed on the last two load rows a little bit....
2) NMAX to 7314
3) NMAXDV 7306,750
4) KFMLDMX  raised last two HPA 900 and 1100 loads after 2250rpm
5) KFLDRL lowered last load row after 1750rpm
6) KFLDHBN all the map maxxed out
7) LDRXN raised a lot after 1500rpm
8) LDRXNZK same as the previous one
9) KFDLULS maxxed out whole map maxxed out to 1275

So can anyone explain what did they do here ? As far as i understand they didnt change AFR fuel target and Igntiion advance at all.....
The only map im guessing from searching for these acronyms that enabled the car to overboost 1.2bar and fall to 1.0bar is the KFMIRL and the LDRXN and the rest are  just limiter maps  ? (LDRXN is kidna also as a limiter)

Is tuning so easy with a stock k03 turbo ? That was so anticlimatctic for me since i come from aftermarket ECU tuning background....

Don't bother looking at anyone else's tune.

This should be FAQ someplace

1) you don't know what their strategy is, and it's often misleading or flat out wrong: we know much more about these ECUs now than any of those "pro" tuners did at the time.
2) they often obfuscate their maps and relocate them to misdirect

S4wiki answers all of these questions.

I do find it interesting to observe such tunes (but it's a bad starting point for a beginner), and try to understand the changes. Even though, after a while i've come to the conclusion some changes really don't make any sense.

S4wiki answers all of these questions.
Not really, i created this post because  i loooked at s4wiki XD and according to s4wiki this file shouldnt work and boost more than stock....
 and i assumed many of you here after so many years you would have checked what some popular brands trend to do
Also what i read here and in s4wiki, is about not overboosting past 1.5bar because then the car will destroy itself because pid will go crazy.....
All the tunes here in Greece in the past 15 years are all overboosting 1.6-1.7 without installing map sensors and rescaling ( And sometimes risking 1.8+ and bending rods after 6 months )
Imagine if i was saying to a future customer. NO that cant be done !!! and everyone literally does it with 95% with no problem.

Now for the file
1) the car is boosting more than the stock file....  It shouldnt do that according to all the things i read .....
2) Maps relocated ? But i just click winols and compare the whole binary file and see if they drastically moved anything....

Whats a good upload spot to put the ABT binary file here so you could whiff it ?

It is almost as if you didn't bother reading my post.

100% bullshit. Bad tuning is bad tuning, end of story. There are a ton of hacks out there *because* people are clueless about how stuff works and blindly copy shit.

Nowhere. You're wasting your time and everyone elses.

If you want answers, post a log, not a binary. There is a reason posting binaries is useless. Go back and read my post, again.

Ive seen those greek me7 tunes (e***s) for a custom hw and theyre completely bs

Lazy mofos wont spent a few days to research 5120 and thats the key explains quality of those "tunes"

2) NMAX to 7314

Probably byte sequence should be switched in winols from HiLo tot LoHi

4) KFMLDMX  raised last two HPA 900 and 1100 loads after 2250rpm

KFLDIMX i believe. No reason to touch stock values on a stock turbo. Raise axis if needed. Bs tune.

5) KFLDRL lowered last load row after 1750rpm

they faced up with overboost with changed dimx. and couldnt get any better idea than limit wgdc. pathetic
