hello everyone

first sorry for my bad english i try to do my best


the car is stock just mod on admission(inlet ,air filter, silicon hose ) 125 000 km 2013 DSG Eu with Mpi stock

new battery, new coil , new plugs

i have hard limitations negative retard ignition when i try to tune with 100% E85 fuel (no test on gasoline)

in my tune i have juste raise up max torque power class xxx and some limiters torque and boost goes up but timming its bad

i have tested many directions : play with fueling (base ,di,mpi) no change

change ethanol calcucation manual or lambda ( i have no sensor ) car works fine but also timming retard
