EDIT i think that finally makes sense.
too true - not to mention the wire that goes into that little vaccume box that controlls the manifold, it must have some function from the ecu...surely
my old, grey POS pulled 115kw at the wheels with a jdm header, stock TB, skunk2 IM, modified stock airbox and hondata. running with the 'ol (stock) faithful b18c2.
it's not a bad little setup really, i'm guessing it'd have made quite a bit more herbs with a decent head package.
the vacuum hose is attacherd to the vaccum tank, that is charged by the engine and activated by the solenoid that is wired to the ECU...Quote:

goos stuff :) so to use the vtir intake manifold properly you need a vtir ecu.
thanks for the help
or use a programable ECU with a rpm triggered Aux. output...
