    Unless your driving somewhere really flat and slow DOD isn't going to help on mileage. Here with 75mph speed limits (so I drive 80-85mph) and hills it never kicks in. I can get better mileage turning it off and doing a good tune than leaving it on. Plus every vehicle I own that has DOD I had a lifter fail so I deleted the actual parts now vs in ecm only.

    Being new to these engines and how they work, what causes a lifter to fail? I'm not familiar with the internals of a DOD/AFM engine.

    Joecar, it won't let me send you the file or post it. It may be sleep deprivation since I just pulled my second 20 hour day in a row.

    Crappy design. The DOD lifters do not have very much travel in them since the part that collapses takes up 3/4 of the lifter length.

    Can the same or better fuel economy be achieved with DOD/AFM disabled and the parts removed? I want longevity and economy, but I do want this thing to be Mommas little sleeper too. I already cut the muffler and resonator out, I still need to install a tube resonator for drone issues and some Dynomat. I know I need to install an intake to free up the other end still.

    Can I set up two tunes, one for a majority of our driving which is 80% city with some added power and then another for those vacation drives. Lord it would've been nice to have a DSP2 switch, LOL!

    Sorry its taken me so long to upload this but things were going on with the vehicle that needed to be addressed first and now that I have dealt with those issues both vehicular and family, its time to work on this tune and make this thing the way it should've been from the factory and better.
