Here you go, it's COS 3 (came from 9381344 then to 12212156 then to 02020003 (COS3)). Careful as it's in SD mode set up for mine (obviously), (LS1, TR230 Cam).

Thanks, ill try it.
Keep in mind a flashing SES light usually means misfires were detected. On cam'd applications, the misfire tables can be too touchy and may require some adjustment. For my car, I just increased them (C5622, C5623, etc.) 200% across the board.

I have a custom tune with the misfire codes removed for a long time and never had any code with the tune that i have with my custom 2000 OS 09381344, When i installed the 2001+ OS 12212156 and change all my 2000 OS over is when i get the SES (Flashing light) and that's only when at cruse or WOT but not a idle. And when i scan the codes there not any!!! Its all most like a ghost light.
