Hi, does anyone know anything about this ECU?? specially im interested in checksum...

My OLS recognize the chk as OLS248 - Siemens Volvo/Renault/Kia, but in im not sure about it. Lot of maps are not cover by chk areas...

Any ideas?

ORI here. Car is Chevrolet Cruze 1.8L N/A

checksum is ok, but think the file is not ori, or it s missing info

File is OK, 100% sure, becouse I remove the F800 and read it. What I dont thrust is on winols Auto CHK, becouse I get lot of areas uncovered by chk.

Why do you said file is not ok?

Can you correct the CHK for me in a tuned file I made with another method than OLS248 module?

Regards!!
