Correction, if you disconnect the battery the light will only stay off for awhile. The computer will recognize that there are no converters. MILs are a must for anyone running an O/R H or X pipe, unless they have a handheld tuner/dyno tune. In order to "plug in" the MILs, you need to disconnect the battery.
Yeah, he asked if he put MIL elims on, would it make the light go out. I said yes, you have to disco the battery first, then the light will go out. Read before you post.
