Does anybody know what the percentages on the far right side of the screen are for? I am curious since cause my friend was told to play with those to try to find a better setting for the primary turbo(doesnt spool fast). Exactly how does this work or what does it represent. I dont want to touch em untill i know what they are.

i think its supposed to be the duty cycle of the solenoid i think, just play with it until it boosts the way you want it and ignore that

thanx Mike, I found my instruction book....I dont suppose that can correct my slight overboost problem, could it?

I'll play with it since i found it!

Yep, that will correct your overboost problem. Turn your actuator duty cycle down and BAM!...lower boost.

Yes, it did help a bit. I pushed them down to about 48% on primary and 50% on secondary. It went from a .90 to .80 better but still higher than my .65(colder temps) I'm sure when it warms up again its gonna be back to raising the duty cycle. I'll probably back off a bit more on my way to the track this Sunday(with forecast in the 40s, might break into 12s this time around!) :bigthumg:

That's one thing you have to worry about with the PFC...the weather. it WILL overboost if you're not careful. https://www.nopistons.com/forums/pub...IR#>/boink.gif

I already found out the hard way. That .90 was scary since it did hit fuel cut. I went from WOT to CRAP....backed off immediately and so far dont think i hurt it.

If you tune for max power you are riding a razorblade if one of the variables change. Best solution for variable induced overboost is to add a $100 popoff valve and set it for just under the max boost you want to allow. I currently have mine dialed in to .95 bar (13.965 psi) on the Commander.



The first time you hit it though you are likely to think its engine rebuild time!!!
