Hi!
I think I have found these two tables in the software for my Seat Leon 1.8T Sport 2003, AUQ engine. They have a similar shape, but one has slightly higher values then the other.

What I'm looking for is basically for someone to confirm that I'm on the right track here, and if I am, maybe tell me which table is which. RPM axis can be found in the attached screenshot. My guess is that axis values should be devided by 4, which will render values between 1000 and 6520.

table1:
90   108.00   111.52   117.00   125.02   131.02   136.01   133.01   126.00   129.00   128.02   132.00   136.50   138.00   130.01   122.02


table2:
90.00      108.00   111.52   117.00   123.00   127.01   131.02   127.01   124.01   126.00   127.01   130.01   133.01   135.00   128.02   120.00

I'd say first one is LDRXN and the second one LDRXNZK

Thanks! That's what I think as well. Then the XDF file I started from probably had them mixed up.

Just some more info for now: After doing some logging, I noticed that the requested load during a third gear, full throttle pull seems to follow the shape of the second table.

look at your knocks, if there are knocks encountered then it will follow LDRXNZK

Right, I'll try to remember to log those. I did however find an intrseting comment in another thread:



So maybe the lower map actually is LDRXN.

LDRXN is always the first map in the file

I have discovered that firmware from 06A906032HS (VW Jetta AWP 180HP engine) has LDRXN > LDRXNZK. Other 1.8T firmwares like 06A906032HN (from AUQ 180HP) or even 8N0906018CB (from BAM 225 PS)  have LDRXN < LDRXNZK.

Since in HS they have SW up to 0008 while on HN there is only SW 0002, maybe that was really bug and in VW they have found and fixed it in latest versions? Or maybe they swapped addresses of LDRXN and LDRXNZK? In any case please who can explain, what sense does it make to lower boost in normal situations (LDRXN) and increase it when it knocks?

I have the HS with SW0007. What .xdf or .kp are you using for yours? Will you upload it please? The ones I have I'm not so sure is for SW 0007. Thanks!

Even more, AWP_HS.LDRXN=AUQ_HN.LDRXNZK=AUQ_SJ.LDRXNZK

Following equation is true for 1.8T map definitions:
AUQ HN1 = AWP HS6[7,8] = ARX HJ2
AUQ HN2 = ARX HJ3
So, if you need a definition for HS7, then just open HS7 binary and import HN1 maps pack. Or another way, vice versa, open HN1 binary with maps defined and then import your HS7 binary as new version. There are many definitions for HN1, for example in this thread http://nefariousmotorsports.com/forum/index.php?topic=576.15

I have a fully defined HN .kp file I have been pulling maps off of and putting into an HS specific .kp file. Not all the maps line up but some are at different offsets. I have located the maps used for VVT in our engines and a lot others. I haven't made translations yet fully but I work on it in my spare time.
Argdubs .KP I believe only has maps that match the locations in the HN/HS/etc...for instance the VVT maps I found in my HS are at a different offset(164) than the HN but the basic load maps are @ the same addresses along with everything in Argdub's .kp. if you would like a copy lemme know. I will eventually post it up in the definition section but not till its finished I think.

Hi Guys,

Did someone find out why LDRXNZK is less then LDRXN in stock many bin files?

Its basically like a safety how much boost your going to run if knock occurs typically 15% lower than LDRXN alot of guys do 99 across the line.

But in most stock bin files LDRXN equally or less then LDRXNZK. it's the main question - why?

Because stock, especially on the 140hp 1.8T's there is enough reserve to run higher charge pressure in case of lower octane fuel to compensate for ignition angle inefficiency, thus retaining the same power with 95 RON as with 98 RON.

On many stock cars the second map is never used, because the switchover is disabled.

Hi prj!
Your thoughts are absolutely logical! Thanks a lot for your explanation!

Could you explain which switchover you meant?

I see, thanks!
