What is the beef with DFM/AFM? I drive my truck and don’t notice anything. It doesn’t even tell you how many cylinders are working at any given time. The ONLY reason I have heard that makes sense to me is it could be trouble long term. There’s a plate with solenoids that are pressurized off of oil pressure. If the solenoids fail or there’s an issue with oil pressure, well there you go- a good way to burn off a cylinder or head..block..whatever. It’s just one more part in the system that can go wrong in a mechanical system. When this was explained to me, I can see why you’d want to disable it. Now with regard to the aftermarket solutions to disable- is this controlled by software or is a physical mod required that voids warranty? Sent from my iPhone using Tapatalk
