this dtc just reading fresh version ISTA from 4.35...
i have try delete dtc and nothing.... still no resolution...

Maybe delete DTC s0777 with DME directly during chiptuning

when tuning i dont touch EEPROM, and only 4096kb flash is touched.
For example when i force monitors on MEVx to ready, and it shows S0777 afterwards.

The tuning detection function is stored directly in the ECU.  The ecu Edc17c50 checks the data set for correctness.

If it is recognized as incorrect 27ab00 is set as dtc in the info memory.

Once this error has been set, it is saved in the eep and can no longer be deleted.

Therefore, always delete the corresponding error with every tuning.

In the case of edc17c50

Error class 27AB00 DFC_SIA_CycSigChk_Data >0
Error class 27AC00 DFC_SIA_CycSigChk_Prog >0

Shutdown Mask 27AB00 DFC_SIA_CycSigChk_Data >255 255
Shutdown mask 27AC00 DFC_SIA_CycSigChk_Prog >255 255

In my tunings, when I create some, these errors are always deleted and when the ecu is flashed back to the original. Is no s0777 set afterwards.

i dont doubt what you are saying. i have been successful in restoring original DME D-Flash, P-Flash and EEPROM to get rid of S0777.

what i would like to do is leave the Tune in and do not trigger S0777

DTC 27AB deleted works fine in EDC17XXX, S0777 is a info fault on ISTA isn't a DTC on DME\DDE
