Chip is right, with only 2 channels you are going to pump some fuel out of time with the cam phasing... but.. we use an algorithm called X-tau, which compensates for the fuel that is left on the port walls ect, used alot for acceleration enrichment calculations.

In general I have yet to have any problems. With timing resolutions of .001ms (thats a thousanth of a millisceond) we can get pretty good low speeds, but yes if the injector is old, choppy and slow then don't expect any magic! Staged injection is a feature of the V4, and one which in that case I would reccomend!
