    0411 OS to suit LS1 swap

    Hi guys, I have an ls1 to fit into a 97 express. It is running the 0411 pcm on the L31 vortec and 4l80E at present. I have researched a lot of info and think I have a handle on most of the swap but I cannot find any info on the best OS to use. At present the OS is 12212156. (02 express van) When the conversion is done what OS will have to be in the pcm to run the LS1? I believe I have worked out the injector wiring but not sure of the coil wiring. Can anyone advise of any extra wires that need to be added? Thank for any info that may help.

    So, with no advise I have spent the weekend surfing the net looking for info. It seems a 12225074 OS might work? Anyone?

    This forum has as much life as a cemetery, you'd be better off searching on ls1tech
