Ross,
maybe your system is better but I have to say, I much preferred the carb FA cars to the toyota injected ones....but I preferred the cosworths to the toyotas...the point I am making is that full engine management is one thing, but simply adding injection will not magically make more power, nor better drivability, in a race application....can it, yes but the 4AGE carb setup was pretty mature and well sorted by then, and with the rest of the development restrictions on the engine gave as much power. It is documented fact the the injected series engines made less power within that rules package. In all fairness this was in the early 90's...think Jaques Villeneuve the yournger, David Empringham, and Patrick carpentier. (I was a young shiftercart driver picking up club rides as I could.)
