Astra J 1.6 ECU Delco E98 Problem Write (KTAG)

[macako6]

Hi DK members, I have a problem writing the ECU DELCO E98 Opel astra 1.6.
When I try to make a change to the SW and if I write it back to the ECU then the vehicle does not start, if I return the original SW then the vehicle starts properly.
I think that's the problem with KTAG can't do CRC but I'm not sure.
Has anyone had a similar problem? And what is the solution

HW: 55595656
SW: 55491601

Use an original tool and you will have no problem I also had a problem with this ECU with K tag clone

Thanks for the quick reply,
my friend I use the original KTAG and also asked for help from Alientech but surely due to the situation in Italy I have not received a reply

Ksuite (Ktag) does not make checksum
you have to calculate the checksum
