Just bought this Hilborn EFI

was just thinking about how you run an Idle Air Control valve on an IR intake. Does it have some sort of injection tube rail to each runner or a linkage kicker like a Dodge TBI? Wild! Boats would seem to maximize the "All or none" personality of a mechanical injection, but EFI would smooth that right out.

I’m not sure exactly how it works without an IAC , but I’m pretty sure it really just uses a TPS, Map, coolant temp, O2sensor, Air temp, EFI dual sync distributor, unless I’m missing something. The whole setup from Hilborn is over 7k.
