Hi I tune a 1.0 VVTI Aygo with M7.9.5 ecu ( not same as ME7.9.5 ) and I can't use it because of Bad Checksum




I try Ktag: Wouldn't write / don't correct CS ( say bad checksum )
MPPS V18: Boot says that checksum is bad too and don't want write...
IO Terminal: Can read / write by OBD without problem but no CS correction




Does anyone can correct it for me?
