Hey everyone quick question for you all. I picked up a translator plus this past summer but have not hooked it up yet also bought a 3.5 ls1 maf. I'm curious about how the extender chips work. I've been using erics chips so far and love them . I'm about to upgrade my injectors from my current 42.5 to 60 motrons. I know I need another chip and want to go with erics again cause he can set it up for my alky system. But how does an extender chip work does it replace the ecm chip or is it a seperate thing . any info appreciated before I spend more cash thanks..
