I'm not totally up on the details, but from what I've seen-
The nutter bypass basically takes the computer out of the picture. I think there's 2 wires you have to cut and splice, and it works better with a different distributor. They say it runs *way* better afterwards.

The Nutter removes the computer from the Jeep. It restores the Duraspark ignition to the same configuration as was found on a late 70s or early 80s Jeep 6 cylinder engine................It does not affect any other emission control equipment, and the remaining emission equipment should be kept and functional, it doesn't hurt performance.

You should replace the distributor with a pre-smog dizzy or mod yours to pre-smog configuration.................Quite simple, really, just some work with a file on the centrifugal advance base plate. Other than that plate, both dizzys are identical.
