So I'm looking into getting a PFC and have some questions. I'm sure it throws codes but does it allow you to see why? Like an under-volt, or resistance change, in a certain component? Just wondering if it will help solve some wiring issues as well as the obvious tuning advantages.

Thanks,
Steve

 

It does not throw any error codes.

It allows you to view up to 8 engine parameters at once on the commander, and has a sensor check screen that allows you to view the voltage of the sensors along with the switching operations of the solenoids.

 

Right, no codes.

 

What about the switching operations of engine relays (i.e. fuel pump relay, etc.)?

 

Yes, it shows the starter, a/c, p/s, f/p, etc
