A few of my thoughts.....tell me if I`m thinking on the right track.

ECM has a remanufactured label on it because it is a preprogrammed hi-performance ecm. If I buy a stock ecm along with new rear secondary sensors, and mil eliminators, it should be enough to get this truck through Indiana emissions....of course unless there are other mils that need attention.

Will the MIL eliminators allow the catalyst monitors to pass, or do they simply just keep the MIL off?
