DoD thoughts

[caffeine]

If closed loop is disabled I wouldn't think the computer would care about the o2 reading. VVT doesn't really have anything to do with DoD but could further improve fuel economy.

also, true DOD shuts down the cylinders via preventing the lifters from opening the intake valve (and possibly the exhaust valve as well) to reduce pumping losses.

Isnt that going to skew your front 02 sensor reading also Just a thought or maybe i am not reading /understanding right And isnt the 3900 VVT ?

[robertisaar]

disable a bank of injectors. either 1/3/5 or 2/4/6. that will keep the firing intervals equal.

also, disable closed loop fueling, otherwise the extra air from the "dead" cylinders will cause a LOT of extra fuel to get dumped into the active cylinders.

I've been pondering making my monte DoD for an experiment. My drive to work is a now 45 minutes on the highway so I could actually log results to work. My plan was to get a extra injector harness from the wrecker and selecting 2 or 3 cylinders to shut down when I'm in cruise with some toggle switchs in the cab.My miss fire is disabled so it might not even set a code. The 3900 has this and I was going to try and find out what cylinders it cuts out. My fuel economy is nothing to complain about at 28mpg but something higher would be something to brage about with a 288hp v6
