I've struggled with this a bit, this is just my guess. If someone experienced could suggest which similar file to define to use it, I'd appreciate it.

Help, I have a problem finding KRKTE, I am creating an xdf file for the first time, the address found on the forum is not very reliable, my findings are not certain, I lack knowledge.

Thank you very much. Did I find good KVB and TVUB?

XDF

I found the reason. The KRKTE value depends on the ECU microcontroller frequency.
This Sharan ECU has a hardware type ME7.5 C2-2alt 1M-flash 24MHz clock.
The previous ECUs with 8-bit KRKTE value had 512K flash and 20MHz clock.
To get the correct KRKTE value, you should recalculate
factor = 0.002133333333 * 20/24 = 0.0017777777775.
Now your KRKTE will be 0.1156 (or very close to this value)
The KVB value in your ECU is defined as 262cc/min.

Question on tvub, the main conversion should be 0.002667 * X or maybe 0.003200 * X or some other, I am installing injectors from AUM and a fuel pressure regulator from AWT and I am a bit confused.
