Whatever it is it must be capapble of precise sequential injector control.
This seems to be the big trick to it. The rest of the GDI system is not so
difficult. I think the Mitsu system uses MAF. I don't know how you'll go
shoehorning any of the GM ecu's onto it though. Sounds like a backward step
to me!

Oh, and the fuel rail pressure is varied to change the spray pattern more
than flow rate (that was a query from an earlier post about GDI).
