Need checksum correction chk

[Ahmy501]

Can someone please check my file for checksum correction i have included 2 files one original and the other is a remap kindly correct if needed this`s my last attempt on this i don`t want to brick the pcm.

ECU is P10 Delphi car is Chevrolet Trailblazer 4.2 in-line 6 engine 2003

Thank you

Are there any reliable tools that can auto correct, i`ve already tried ECM titanium i don`t think it did a great job though because when i reload the corrected file it always says checksum error and tries to auto correct it but i really do not trust it . any ideas

the file that you called origiale remapped and are equal there are no major changes ..
you can write the original file and remapped files without seeing any difference ..
for cks you should WinOLS

Thank you for ur input, actually there are minor changes if you compare the two files in a HEX utility you would see offset 00008000 , 0000DC30 . 0017200 thisn`t a total remap its basically immo off only.

Have you run chksum on the remapped file?

the rammaped was edited in tuner cats and saved as .CAL then a converter was used to convert it back to .BIN i had to hex edited the converted file cuz the ecu SN, VIN all were FFFF after the conversion

Hello
The checksum of your files is ok. Legal Winols shurely supports this ecu!

I am looking to learn. I see you have Tunercats that can edit this file so why use WinOLS?
