Lightbulb FYI: Invalid Checksum (UTEC Map corrupt)


Not sure if any of you out there have attempted to modify a UTEC map file with notepad yet or not but if you do, the file will become corrupt.

The end of the file contains a checksum calculation of all Fuel/Timing/Boost (and name/comment) values. The UTEC creates this checksum value then truncates the HEX value to a 16-bit number.

If you'd like to modify a map file without being connected to the UTEC, stay tuned for the UTECLogger software which should be released this Friday afternoon.
