    99 OBS Tahoe 0411 swap

    Hello I have a few questions hopefully someone can help with. I have an 0411 pcm from a 2002 s10 with the 4.3/4l60e combo is there a way using hp tuners to either activate the other 2 cyls and displacement to make it run the 5.7? Or maybe segment swap the engine OS? Any ideas would be greatly appreciated because this had been a drawn out project and now I could really use another running vehicle.

    Thanks,

    If the part number is the same just flash it with SPS to a good VIN of a Tahoe and you are set.

    You need to segment swap the engine and engine diagnostic segments from an 02 Express van. Make sure the OS matches. Should be 1221256 for 2002.
