Hi all.
I have a Skoda octavia 1 with 1.8t 180hp AUQ engine (032HN ecu) with stage 1 and next modifications:
- FMIC
- 76mm downpipe
- evap deleted
- sai deleted
- n249 deleted
- cat deleted

Car works ok at 1-1.1 bar maximum boost with 210 hp and 300NM.
I want to make stage 2 and i saw all tuners estimate 230-235hp and 360Nm .
I choose methode with big injectors from audi tt 225 hp BAM engine 386cc at 3bars . I don't choose 4bars fpr and standard 312cc injectors from two points : one - in the future will change the turbo and two - i think stock injectors works with 4bars fpr at their limit.
So if i change injectors after i read all wiki and all thread about this and with user ROGERIOUS HELP (THANKS YOU VERY MUCH) i understood i must change next:
- KRKTE
- TVUB
- TEMIN
- TEMINVA

Please give me your advice for next questions
1.TEMINVA it is the same with TEMIN value i saw , Correct?
2. Must i change FKKVS for fuel modifications?
3.With bigger injectors and all modification in file from above will not have any more power, Correct?
4.For more power i must increase boost? Correct?
5.For increase boost i must change LDRXN only? If not please tell me all variables / maps to must change.
6.It is necessary to change MAF with bigger one?

Many thanks in advace to all.

1.yes.
2.it is for injector non-linearity and fuelling inconsistency.
3.yes, bigger injector just gives the possibility of bigger power.
4. Boost or timing is the quickest and cheapest way yes.
5. LDRXN determines maximum torque output of the engine and therefore also max boost.
6. Bigger MAF shouldn't be necessary for a K03s.

Thanks a lot for your fast answer.

Please give me an answer for point "2. Must i change FKKVS for fuel modifications"
because i dont understood if i must change it or not.

And for "5.For increase boost i must change LDRXN only? If not please tell me all variables / maps to must change." please tell me if i must change other maps
For this point 5 please tell me i have values in this stage 1 file higher then an audi tt 225hp , must i increase more?
This is my ldrxn

Many Many thanks in advance.

If you can find the specific calibration data for the injector, it would be best to use that.
And since you have OEM injectors, that should be relatively easy to do.
But if you can't, FKKVS fixer is a great tool for creating your own data.

Required boost calculation isn't the same between the two ECUs among many other things.
So you can't really compare engine power and/or boost with the two LDRXN.

With regards to 5.LDRXN, you need to decide what boost you want and log the requested and actual boost and adjust LDRXN so that you get the boost curve that you want. Also remember that you specified load comes from KFMIRL and LDRXN limits it, so make sure you request enough load in KFMIRL. And with that comes the KFMIOP adjustments. There's better explanations than mine in the S4 wiki and in lots of threads on this forum

Thanks a lot fot yours answers.
I'll study and will come back with questions.
