atomgonuclear has no tact, but some of what he posted IS worth reading because it's true. I didn't read all three pages but I see no reason for him to be offensive. A more confident and mature person would have set a constructive tone.

Where he's wrong is when he implies that only the newest high end vehicles use sequential injection. The Honda Civic has had it since about 1990 across all of the available FI engines. And this is an economy car. Toyota was slower to adopt it on their low end cars but I assure you that all of their USDM 4 cylinder 96+ cars feature sequential fuel injection. It certainly sounds like he is quoting an unrevised text book on that one.

He's also wrong in his assumption that there is nothing to be gained from such an experiment and that if there were mpg gains to be had, the manufacturer would have implemented them. Such an implementation would have been very expensive to develop and manufacture and there would be very low demand for it. It's likely to cause hiccups in drivability that are not acceptable for a production vehicle but which may not matter to someone on this forum.
