ktag has wrong cks for this ecu

is wrong because you read/write mpc 512 kb separate.read maps 2.5 mb ...then ktag will correct checksum

ktag has not wrong checksum...
ksuite does not correct checksum in MPC...
ask support...

with this kind of ecu and KTAG, has to read/write map area as @aem wrote...
and then will correct checksum automaticlly...
if read map area, SW reads part of flash and part of MPC...
