I hope this post stays here. I don't want Profec settings from a MP3 running a T3 setup or something.

Any Mazdaspeed guys with Profec B Spec IIs figured out the settings yet? Yeah I searched, only found posts from people still toying with the settings. They didn't work for me. This car is real finiky. Haven't found a sweet spot yet for anything close to 9.5-10psi. Boost falls hard when I shift. No leaks. Holds fine through the gears. Just only at 7-8psi.

So, any settings you Mazdaspeed guys have for SET, GAIN, and SET GAIN that work for you would be great. Willing to try what you got. Please list your mods too. Thanks! Maybe this post will benifit others in the future.
 
I have installed mine since 3 weeks but I don't ajust it because here it's the winter. But after installation I have try it a little bit and me too I have seen a lot of spiking . In the manual , it's specify to reduce spikes , you need to reduce the set gain , and for stabilise the boost you need to increase the gain .
 
well i will tell ya that you might be lucky if you can use someone else's settings and they work the same on your car... i hate to say it, but when i finished installing everything on my buddy's msp that i have on my msp, i tried using my settings on his and it didnt have the same effects with his car.. i dont know what that was about but it was pretty wierd.
 
im lookin for some good settings to, im goin out after i figure out why my a/f gauge is reading lean and i'll get it tuned to a constant 10 psi. i wish i could talk to cullen b/c i hear he is the one to talk to about the profec B
 
well the best thing to do is get on the highway and tune it in forth gear... you should maintain a constant boost that way...
