Original file plus new file should be needed to do correct checksum ..

Where is your problem m8 . Not enough info?

m8 the ori file that you upload has the AD08 checksum. Your mode file has 8F83. So, i fixed your mod file with the same checksum that you uploaded as the ori file from your ecu. Try first to upload at your ecu the ori file. If the engine starts, upload the file that i send to you. If your engine doesn't start with your ori file, something was wrong when you tried to read your ecu at the beginning. If again your engine starts with your ori but not with the mod, then something happening with your modification. I hope that you know what are you doing with the "egr off" reprograming and not just use these free programs that you can find on the net. All these are simple "shit", don't trust them. Find a pro to make your egr to work better or to eliminate completely through the "egr switch". These programs just trying to guess the switches and change some values, for some ecu's working but not for all.
Good luck
