Question installed vafc...car now runs like $&*#

just installed a VAFC and set up the initial settings step by step and started up my car and it runs like shit.

rechecked wiring and the car only runs bad when the vtec sol. wire and the pressure signal wire are connected.

I left all the "monitoring" wires connected and disconnected the VTEC SOL. , VTM, PRESS. SIGNAL and reconnected the stock ecu wires and the car runs fine again...

i dont get it...
and i know its connected right because the pressure signal, throttle signal, rpm,and voltage signal read out in monitor mode

what pessure do you have it set at 760, or is it set for boost??

also do you have the right throttle setting and sensor type????

all these make a difference

gonna recheck all wiring today. the sensor type is at IN 06 OUT 06 . throttle is at diagnal up right arrow ( / ) .. vtec type is set at 1

if you hook up the vafc and and perform the intial set up but leave ALL other settings at default, the motor should run almost normal right?

would really help if someone could help me set it up as the book isnt very helpful describing what things are and what they should be set at
