Can't find "official" forum/support for Apexi

Maybe someone here can help me ?
Have problem with idle.
With stock ecu car idles fine, TPS reporting about 370mV at idle, rpm about 650-700.
With PowerFC car don't want to idle and dies, until i set TPS to 800mV, but then ecu thinks that throttle is slightly open, and "idle" is about 1000-1100 rpm.
Can't start idle learning procedure, like it is advised in manual for PowerFC.
