I heard this complaint on the race car tech forum ... about how the Power FC has a issue with leaving the solenoids in the secondary position after rpms dip back down into the primary turbos range. I was told by my shop that you can adjust the transition point for the solenoids on one of the pages. Is this true and how adjustable is it?

 

Nocab and I did some testing with the data accessible from the Datalogit hooked up to the PFC. Nocab got his transition (back when he was running twins) down to about .4 sec, if I remember correctly. He also adjusted the pre-control rod along with the software changes. I got mine down to about .5, with no hardware changes, only software.

I haven't tried to do this with a Commander...don't even remember if those screens are accessible from it (I don't think they are, but am too lazy to check for you).

Get a Datalogit...or find out who has one in your local area and buy them dinner or some beers!
