Since replacing an AEM with a PFC, my air pump no longer works.

Is there a trick to this with the PFC with datalogit software? The AEM software had a setting for the air pump but I don't see any options in the datalogit software? I am using a GM electric air pump. How do I get it to fire up at idle and cut off at 3,200RPM.

I have 5.08 datalogit software.

with the pfc, theres a way that you can turn off the O2 feedback from the airpump ( for those that have removed it), did you turn the O2 feedback off when you were first doing your idle learning?

Shifty, with or without the o2 feedback checked, the air pump does not run. The car is tuned well and runs well but I have failed emissions testing by a wide margin. What I am trying to do is to get it to kick on & blow into the cat and get some burn.

It was awhile ago when I was playing with the AEM but I recall configuring an output to switch the air pump on & off. Is there a comparable PFC setting?

No, there are no settings with the PFC. Take a look at the Air pump relay, if that checks out, then you may have the same problem that another user just recently posted about, where as the PFC circuitry for that particular ground seems to be fried.
