I have two pairs of 24pin chips that manage my car’s fuel system in different ways - stock and performance.
I’m wondering if their is a reliable/simple way to switch between the 2 pairs electronically so I don’t have to take my car apart to change the fuel management system.
I’m picturing a little pcb with the 4 chips and 2 outputs, with a switch to toggle between both modes.
48 relays is an option be feels overkill to me. i’m wondering if their is some kind of switching IC you could recommend.
