LSX454 E67 checksums disabled

[Xman]

I am trying to tune this LSX454 crate engine with the supplied E67 and harness. I was able to read the file with no issues, but it says Checksums Disabled and will not let me flash.

Thanks for the help in advance23075

This is normal for those GMPP files.
You simply correct the checksums, if you are looking in V7 there is a button just above where the checksums are shown called "Update Checksums", click that and resave your file.

That's what I did just making sure before I tried to flash it. Thanks

Good decision to check, when they are marked as disabled it is usually ok to correct them, if they ever show as incorrect (with a red marker) then that would indicate there is probably something wrong with the file and it should not be used.
