P59 ls1b cos5 setup help!
I have a 2002 Z06 originally a 411 pcm. I am switching over to a P59 ECM # 12589162 with OS# 12592618. I need help deciding which os to use. This is an ls7, I'm using a lingenfelter box to convert the crank and cam signals. I would like to use cos5 for nitrous in the future. Also running Flex Fuel. My thoughts were to load cos5 and then copy the tune files from a 2004 z06 file. I have already repinned the ecm connectors. I found a chart to choose the COS# 051200##. Just looking for some direction on a gameplan. Thanks for any help.
