You might get a lean code from that, but likely not.

Here in Brazil our gasoline has 25%Etanol (ABCD are you from Brasil too ?) the original files are the same ROW and doesn´t throw DTC.

if E25 has different stoich AFR than pure Petrol then you have to change KRKTE for sure!

I agree, but here in Brazil it doens´t like would be Cheesy

As example, Golf MKIV has the same injectors and file than ROW... if you see channel 32 you´ll see about +8~10% in LTFT.

Same thing with Jetta 2.0 TFSI, about 10~12% LTFT

Just few cars have something to deal with this, for example A3 180 that use 512kB file and Audi solved using injectors 10% bigger than ROW but keep the file the same

for sure the ECU will adapt by at +8-10% as you said if you have KRKTE for Petrol and you put E25!
That is why they offer E85 without software change!

I used to mix a couple of gallons of e85 with each tank fillup to get ~E30 in my A4 and S4. It was right around 25-30% that I would get the lean codes, just fyi.
