Yes Frank - it will. During those times when the engine consumes fuel to make power we don't use (light throttle and cruise conditions) switching off injectors will save fuel. Not as efficiently as some other methods granted - but when you think of the effort we go to with hypermiling techniques this is a simple idea to get similar results. The real question is how clever has heihetech been with his design to get the best from this technology?
If his customer liason skills are anything to go by, I think it'll have a few bugs in it!
