What ^ said. But LDRXN and other stuff. Go check it.
With E85 you need to change krkte and some injector tuning, but you can safely set timings to kfzwop usually.
Everything you asked is on the forum

yes of course
KRKTE
TVUB
KVB
LDRXN
but for the boost there must be other maps to modify?
LDRXNZK....
I have a few maps on my xdf but the units and axes are not all good. Can someone look at it please?

I don't think anyone bother help if you don't even tell me what your ecu part number is, now we have to dig it out from your binary. don't hide it.
Btw, your injectors don't go very far with ethanol. Increasing the power ends up very short with them if you want it to run on ethanol.

thank you
I modified with ecu number.630cc are too small for e85 and a bit more boost?
I have the stock K03 to remain reliable how much can I put 0.8 /0.9 bars in it?

thank you very much TeKnoFi.
LDRXNZK can remain original? is it protection? does it lower the pressure in the event of a blow?

I admit my first reading of the ecu went well in 7 minutes. but I worry a little more about the writing. because I need it to go to work  . maybe I should buy one backup ecu at 100 euros? because given my level I have a lot of log tests and adjustments to do. if the ecu crashes it's easy to put back in original boot mode? by obd and for the cold start with E85. where should I start looking? is there a map for the warmup?  thank |

Yes, get a spare. Learn how to bootmode and do it before you need it.
Yes, there are warmup maps.

So that boot mode can be turned on at any time while ecu is attached in the car. I made a small hole through the ecu shell and sealed it, so whenever I want I can get the ecu into boot mode and do a repair via obd if normal writing fails (common with mpps  ) |

I'm interested, I thought the bootmode was as simple as reading with nefmoto since there is the option. how does it work? soldering to do? |

Same bootrom version and pcb design files can be crossflashed without any issues. Pretty much anything but please dont make me look up all the info.
Post the whole output from me7check of bins..
It looks like that is even the same ecu so one of the softs is newer so tldr you can. Dont forget about your eeprom

hi,I ordered a spare ecu. how do you read the eprom ecu? I understood that it is necessary to be in bootmode (pin 24 to the mass or by obd which software?) for the moment I manage to read the eprom cluster with vag commander. I equipped myself with me7eeprom me7_95040
but I am far from having read everything and understood everything. I have plenty to do
sorry for my google translate
