Hello!

My friend had his w202 200cdi merc "optimized" by bulk tuning shop and the car didnt work properly so i made him a new file but now i cannot seem to calc the checksum even with mpps, ultimo cs corrector or ECM titanium. Ultimo and mpps both say cks zones 2 corrections 1 in red and ecm titanium doesn't find any driver for it somehow. :shock: Ive done many of these older mb edc15c5 ecus checksums with ultimo or ecm but now even looking at the ecm drivers for 102hp model of the 200cdi any of the ecu numbers doesnt even match the ecu in car so i cant really choose manually the driver for it. Anyone here that could help with the cs ? I have attached orig and mod file!

Greetings from blazing hot Finland! :D
