as said above...acis works great with larger turbos
the way we hook it up here (like newguye's set up) does not require any adjustment to the acis actuator
items needed
fully operational acis manifold and actuator---needs drilling/tapping and fitting stock AIT sensor
1 normally open VSV (it should have 3 ports, 2 "free" and 1 with a samll air filter connected most likely)
some vacuum hose
1 one way valve
1 vacuum canister (a sealed container with 2 ports on it:haha
1 rpm activation device
here's how to install
find a vacuum source/port in the acis intake manifold ---->connect vacuum hose to the source/port and run hose to one end of the 1 way valve (the direction of the flow is VERY important, basically you don't want boost reaching the vacuum canister) -----> connect vacuum hose to the other port/end of the 1 way valve and run/connect vacuum hose to one of the ports on the vacuum canister----> connect vacuum hose to the other port/side of the canister and run/connect hose to one "free" port on normally open VSV----> connect hose to the other "free" port on the VSV and run/connect to the ACIS actuator port
you are basically forming a "looped" system
the VSV will be controlled by the rpm activation device/signal, which will operate the short runners. basically when activated, the VSV will switch to atmosphere and allow the short runners to open. when deactivated, the VSV will keep vacuum in the canister to hold the short runners closed
Disclaimer---all risks are at you. i take no responsibility for any damages
will try to edit it as i find more time...maybe add some pics if newguye has some time
