What is the latest model/version of PFC being sold today?
Is there a downside to buying an used/older unit?
Can the PFC software be updated?

 

I believe for the FD there's primarily 2 versions - the old one and the new one . The new one is better just since it uses the new universal commander. Not to mention they're so damn cheap new (Around $700 with commander now) there's no good reason to save a few bucks for a junky used one.

Do you know how long the 'new one' has been out and is there a way to identify one from the other?

 

Dale,
Just found your PFC FAQ so you answered my above question, great info.

I had been told the PFC will operate the emissions but your FAQ makes it seem as though it will not. I have the air pump, ACV and split air pipe installed, how are these or can these be operated?

Thanks,

 

As far as I know, it operates the stock emissions equipment and you can pass a smog test with it. I'm running mine with the emissions, and everything works great - airpump, etc.

Where in the FAQ is it ambiguous about emissions?

In the FAQ Installation section:

There are 4 wires that need to be disconnected from the wiring harness for the PowerFC to work properly. These 4 wires are for extra emissions devices that were added in the US market, but weren't in the Japanese market. These 4 wires are for the EGR valve control, the EGR switch (the feedback in the California ECU cars to tell the ECU the EGR valve is working), the accelerated warmup system (AWS) which gives you the 3000 RPM startup, and the Split Air Bypass solenoid, which alters the flow of airpump air to the main cat.

My concern is about the air flow to the cat. I've heard, without it the cat will not work properly and eventually plug.
