Stage 1 Kia Ceed Kefico CPEGD2.40.2 using FLex 

ECU belongs to a Kia Ceed 1.0turbo 120hp.
after writting bench car no start and flex would not comunicate with ecu anymore but ID ok. so i had to open ecu and recover in boot. i m still investigating if problem was file, checksum , or flex.
Warning: this ecu is v difficult to open. Glue is very strong.
Please share in comments if u had any trouble with these ECUs.
This is not a easy ECU to modify, lots of torque monitor strategies.
