I've upgraded a VT to COS 1 for SD and am using 92115988 calibration from a12225074 O.S. and it will only use the low octane spark table. It's not a huge issue but it would be nice to know if anyone else has had this issue. It's not logging any KR, burst knock is zero's.
Cheers

Yep twice, as I though maybe the first time had an issue. When you look up the O.S. it comes up.

Well I got nothing except perhaps trying an alternate GM calibration and then upgrading that. Have you considered just using OS3 or OS5. They have alot more features than OS1.
