Hello
Everyone I am currently trying to read an MED17.3.5 ecu from a 2019 alfa Stelvio qv. I am currently using ktmbench which has pcmflash module 71 and 53 activated. Module 71 lists tc1793 protocol. The ecu was connected according the pinout diagram provided with the software. I am getting failure to read when even just trying to id the ecu. I attached some pictures of the error, connections and pinout I am using. Does anyone have any ideas of how to go about reading and writing this ecu? Can anyone please help I am truly stumped thank you.

I think that MED17.3.5 is not listed in PCMflash 71 module.

Not to argue with you sir but the med17.3.5 uses a tc1793 and on the webpage listing for module 71 it lists MEDC17 (TC1791/1793) EEPROM


Is there something else I am missing ? does this ecu need to be done under boot mode with module 53? if so would you have pinout for boot mode and boot pin? or do you think I should try to use clone Ktag with 2.47 sw ? thank you
