Thanks for your help. After putting your file to the ecu the car start and drive ok , but the ecu become lock out , no start , no crank, no communication with diagnose after locking and unlocking with the remote key few times , write again the file to ecu, car can start but same problem after a few locking and unlocking with remote, now looking for another ecu to try again see whether it is hardware or software problem

Is a sw problem. Check-sum incorrect. Test this file:

Any chance of a copy of this file daughters car has fubared ecu (same soft/hardware version) in her 207 due to coolant ingress and can't dump old flash.
I have got a used ecu but need to make it immo off or virgin

Hi, I have the same problem with a PEUGEOT 207 with MEV17.4 (TC1796)
here is the original flash I read with ktag

if you can make it IMMO OFF with correct checksum would be perfect
thx a lot in advance

Hi,

I need calc Checksum MEV17.4 TC1796.
ECU is has only Flash without EEPROM

I have IMMO OFF but I do not have checskum (Fgtech, Kess, Ktag no calc CS)

Thanks

cks correct

[spider-wifi]

cks correct
Ktag writes a checksum error and does not write the dump, next step?

[pinotec]

try other toools if you have any

[spider-wifi]

try other toools if you have any
I tried to Fgtech v54 and Ktag and the same checksum error (original dump even without a checksum write OK)

[spider-wifi]

no one has the correct recalculation of checksum?

[vak5]

May be because this processor has OTP, no will checksum from original to another one?
