Why would I need a boost reference at all if it is being injected pre-turbo? Wouldn't it just inject based on air flow to achieve desired AFR?
I'm also slightly concerned about the potential kaboom if there is an intake backfire with the entire pressurized intake tract filled with air/fuel, which may or may not include an intercooler (I'm also looking at liquid-to-air charge coolers).
I'm very intruiged by the throttleless idea - I've never heard of such a thing - but how would I control engine power/RPM? If I just control fuel metering then I would end up going lean during anything but WOT, which I assume would be very very bad.
