It still says inside ---> Audi.....A3.....1.8T.....1999.....Turbo-Benzin.........150PS / 110.3KW.......557B .....0261204806.....358127....PLCC44.........0261204806..
It is for a 4B0907557B - D03 - 0261204806 - 1037359157 - M3.82 ECU.
I think that is the M382 that have been floating around since many time.

This DAMOS is good to my file, i find the maps in my ecu file, are not exactly at the same address, but well next!

If i put the file of A3 1999 1.8T M3.8.2 0261204806 on my ECU the engine will works? its better for gt25 turbo charger on NA engine?

KFFMLTA effects just when the engine is cold?

soon i will post vídeos of my passat here!

That is what many of us do with this type of Damos files. It is not exactly the one that I need but serve as an excellent guide to find as much info as we can. From my little experience with M38x/M592 ECUs NA and Turbo ones are different, then you can not use a turbo file in a NA ECU. I have tested with a M592 NA ECU with M383 Turbo file and doesn't work. KFFMLTA is a weird map, as you says seems to me that most control is when engine is cold or something warm.

Thanks!

i will try now with this DAMOS!

Hi people!

There is pair of groups related to injection control at startup:
ESSTT: A 13.0  Einspritzzeit Start           
FHSA.0   4x1   Heißstartanhebung     
FHST.0   4x1   Heißstartaufregelfaktor     
FKSM.0   9x1   Kaltstartfaktor     
FKSM.1   9x1   Kaltstartfaktor     
FKSU.0   2x1   Abregelung Faktor Kaltstart über Umdrehungszahl     
FKSU.1   2x1   Abregelung Faktor Kaltstart über Umdrehungszahl     
FKSWDK.0   5x1   Kaltstartfaktor abhängig von DK-Öfnung     
FSTD.0   4x1   Dichtekorrektur Startfaktor     
FWSTT.0   6x1   Wichtungslinie für Wiederholstart     
KFKSNM.0   6x4   Abregelung Faktor Kaltstart über Drehzahl und Motortemperatur     
KFKSNM.1   6x4   Abregelung Faktor Kaltstart über Drehzahl und Motortemperatur     
KFWKST.0   4x4   Wichtungskennfeld Wiederholkaltstart     
KFWNST.0   4x4   Wichtungskennfeld Wiederholkaltnachstart     
NKSM.0   2x1   Drehzahlschwelle von B1 -> B2     
TMH   1x1   Motortemperatur - Schwelle heiß     
UKSS.0   1x1   Umdrehungen in Bereich 1     
           
EVSTUE: A  9.0  Einspritzung Vorsteuerung Übersicht           
TLST.0   1x1   Startgrundmenge     
TLST.1   1x1   Startgrundmenge     
TVUB   5x1   Spannungskorrektur

But basically TLST.0 / TLST.1 is Startgrundmenge in ms. (Startup injected fuelmass in ms.)

with 52lb injector fails on heated start, dont start without open a little the thorttle.

i have the same phenomenon. my starter turns very fast, strong and long but car does not always start.
when i touch the pedal very light, very short, almost not touching... the car starts.

whats the general advice on this?

You can adjust KSTT maps, Ive done this before with large injectors when I have that same issue. Watch when defining them most of the damos or map packs that are floating around have them defined wrong. High low or low high is backwards
