just hooked up PFC are my voltages good?

Iam currently running non seq, street port motor (just got it back from rx-7 store), and a auto trans. with the key in the on position these are the readings I get.

PIM-2.60
VTA1-1.45
VTA2-2.90
VMOP-.83
WTRT-2.3
AIRT-2.26
FUEL-3.84
O2S-.03

also how do I know if the PFC is finding errors?

With a warmed up engine these two TPS voltages are way too high.
VTA1 should be about .48.
VTA2 should be slightly over 1.0.

These are higher even for a cold engine unless your cold start greatly opens the throttle.

YES, YES; but check the TPS when fully warmed up.

How about getting out the FSM, all the voltages you are looking for are in Section F.
