Other than Bosch to my knowledge the others such as mentioned are using modified units running a more gasoline injection strategy. They work but are crude compared to the volume injection strategy used by the OE and Bosch which is basically the same thing. They are also some serious money and no matter what are never going to be at the same level as factory as with any aftermarket injection. The factory uses a total volume target strategy that is a combination of rail pressure control and injector opening. With a pre injection and main injection on the older engines that merges into a single main injection at higher rpms. The calculated volume is then trimmed per cylinder based on the rate of acceleration of the crank per cylinder.
