Hey folks,

I've got a really strange issue that I cannot for the life of me work out. It only just started happening on recent tunes i've been updating.

I have attached the 2x tune files. The 0000.ctz file passes all checksum. The 0008.ctz file, only has 1 small change, where I changed the cranking VE %age, then saved a new file. It's now coming up as checksum invalid. Rather than "Force all Checksums to be correct", am I doing something seriously wrong? Or did my V8 Tune Editor just take a dump? File version is 8.3.4.16. Any help would be great! Thanks!
