File is not checksummed. Could someone fix the checksum please, tried with Winols 1.5 but it doesn't seem to get all summs correct.
Anyone care to take a look?

Here are the files with Lambda OFF, the one called "checksummad" is summed with Winols 1.5. Bricked my ECU with that one and had to desolder the chip to get it going again.

Anyone care to take a look what might be wrong with the file "checksummad"?
