KIA EDC17CP14 Tuning

[Inquizit0r]

I have strange situation with KIA Sorento EDC17CP14.
Readed with KTAG clone 7.020 - all ok. File was tuned and wrote to ECU - no DTCs, car starts and stop. Flashing MIL, glow plug and Immo pics.
If file has changes only in 2nd datablock - all ok. Car starts, working, etc.
WTF?
KTAG can't calculate checksum in 1st datablock? Or what? I have same issue on two cars.
Plz, help me.

Mate,

Make folder, put all files in that folder. I mean:
-EEP
-FLS (if ext flash will read avail)
-MPC

Tune the MPC and delete ori mpc.
Select full write and choose backup.

Ktag will now write full with calculate checksum and car start.

I have doned this car 1 week ago with ktag clone 7.020

But, when i write full backup and choose compressed single file, KTAG can't use EPR and MPC file? And if i choose MPC as full backup KTAG show "Invalid backup file" message.
May be i doing something wrong?

You need choose " backup" file. no mpc, fls or eep
