Someone on the Corvette Forum posted an in-car video and I can clearly see that his CAGS light is working as a shift light. You can see that here:

I have an old version of LS1Edit (1.21) and this option is not available in my software. I emailed Carputing about this and I was told that they do not think their latest version (1.5) supports this feature. Someone posted a screen shot from HPTuners and it certainly appears to be an option in the HPTuners app.

Does anyone know if LS1Edit 1.5 supports using the CAGS light as a shift light?
