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
