Is there a straightforward way to disable the cold start sequence that lights off the cats? On a car with an off-road pipe, it's uselessly LOUD. As in, shakes my whole house loud. The sequence usually involves a BIG spark retard and additional fuel to light off the cats.
Is there a simple way to "disable" this on the Copperhead PCM? Searching in the software and on these forums didn't turn up anything.
