What is the checksum fix for the 32-bit Subarus?
With the 32-bit ECUs, Subaru uses a checksum that verifies that the data in the rom is not corrupted. When you edit a 32-bit rom, you can cause the ECU to enter limp-home mode because the checksum no longer matches what is expected. Fortunately, RomRaider has a parameter called Checksum Fix that allows you to overcome this issue, regardless of the changes you have made. Simply click on the “enable” check box and the checksum problem will be fixed after you save your rom.
