Title: errors?? Post by: EuroXs4 on December 10, 2016, 12:53:56 PM Hey guys I am having the following problem.I am trying to read a me7.5 ecu with the nefmoto software.I keep getting this error:
Immobilizer not Authenticated and security access is required???Anyone know why???I can read the flash fine in boot mode.However in slow init mode i have this error.Anyone know why this is???Ecu has a stage 1 flash file from the me7.5 thread.Modified immobilizer flash to match the vehicle its installed in.Both the 95040 and the 29f800bb checksums have been corrected.

Title: Re: errors?? Post by: TijnCU on December 18, 2016, 09:56:02 AM Does your bench harness give 12v on pin 121? I can bootmode flash without it, but not with nefmoto.
Title: Re: errors?? Post by: EuroXs4 on December 18, 2016, 11:36:58 AM No I did not have pin 121 powered up.With galletto i can do it no problem without pin 121.With nefmoto no way in hell.So For nefmoto I need to power up pin 121??Ok I just set immo in 95040 to off and powered up pin 121.Still No change.I noticed the ecu is missing the ground pad from the pcb.looks to be lifted or missing.Could this be related to my issue??I thought the ground pads was just that??circled in this image whats missing.
