Hello, trying to tune M50b25 on Bosch Motronic 403 and I need to disable lambda feedback or delete it from the ECU. Does anyone know how to remove it, DTC or feedback tables ?
Thanks.

Set all values to 0 in this table will turn off O2 regulation and adaptatives, did some tests this morning and it works ;)

Hi how are you
I know that you put a lot of effort in creating that xdf and i noticed that the addresses cover the 2 chips for 403. May you please share it or is there a way i can get it?
Thanks in advance
