Came across a random observation today and I can't figure out why or what's going on.
Car is a 2003 C5Z, stock OS is 12593358
I table-by-table copied my current tune to a 2002 C5 Manual trans tune file with OS 12212156
From that tune I converted over to COS5.
The tune is set to 7000 RPM rev limit. With the 12593358 based file, it works fine, as expected. With the COS5 (02020005) tune, it hits a limiter right at 6500rpm.
Did multiple back to back test to make sure it wasn't a fluke and got datalogs. My best guess is I have something weird set in one of the custom OS A series tables, but I can't find it.
Thoughts?
