i had the set % at 100% :P if ya don't mind post or PM me with the settings you are using to get 19 psi without spiking or fall off.

 

Here are my settings:

Boost setting is: 50%
Gain: 14%
Start boost: 1.10 kpa

That produces ~19 psi sometimes up to 19.5 psi or so.

I only have an HKS downpipe and stock exhaust and stock air filter.

I just installed mine last night, my settings so far:

Boost: 50% = 1.35 Bar
Gain: 20% I found when I went much lower the boost would decrease in the high RPM's.
Start boost: 1.2 Bar

It seems to maintain 19.5 to 19 PSI throughout the RPM range. I am still not done adjusting, and it is really helpful to see what others are using. On mine, with the gain high enough to prevent the boost from trailing off it does intermitently fluctuate a little +/- .5 Bar.

Other mods are: 3" turbo back (RMR) with Random high flow cat, K&N stock filter, and Greddy type-S DV.

 

Ok, as you can see, I'm a Honda Civic owner. I've tried looking everywhere for instructions on the new Greddy Profec B Spec II boost controller, but there is no such place. Can anyone in here please provide me with the instructions. I've been playing around with the controller, but blindly. I set my high boost to 14psi, and low boost to 10psi. I set the gain for both the low and high to 20%. You mention start boost, but I don't see that option anywhere. I set the warning at just above my settings as well. After doing all this I took the car for a ride. It boosted past 15psi. My car can take the 15psi, but after that it will begin to detonate. So, I lowered the high boost to about 12psi. Took the car for another ride and the car would not boost past 5psi? This has happened twice now. Do any of you know what is going on? It seems that the boost controller is cutting the boost at 5psi for some reason. Also, I believe that the boost controller has the capability to show pressure in psi vice x100 kpa right? Well, how do you change it so it shows psi instead? I would really appreciate any help that anyone can provide me with and I would be really thankful if someone can give me the full instructions on the controller. Greddy does not have the instructions on their site either.

ps. My Civic does have some kind of Mistu. part, it has the 450cc injectors of an Eclipse as well as the clips.
