Please help me limit my boost!
Good day all,
So I've been really out of things for a while... been travelling all over the world for work and parked all of my cars for the past 6 months. Now home and was really feeling ambitious lastnight.
Worked on my Adaptronic Select install to make the car better. Set the jumpers to allow the factory ECU to handle the idle and now I love my car again!
Well, long story short, I also finally installed an Electronic Boost Control Solenoid and just need some good advice.
In the past with the stock wastegate, I would see peaks at 12 PSI and normally sustained boost runs at 10 PSI. With the EBC in place, I can now do a lot more with the peak boost.
Just wondering what you guys suggest for a highest sustained boost level for my configuration?
I am running a BEGi 2554 "S-2" kit with the intercooler #1, Adaptronic ECU, 600 cc injectors, IK22 plugs, 3" turbo back exhaust, Spek 6-puck clutch, and AEM UEGO...
Right now I have the knock detection ready to pull when it feels detonation and I even have the headphones pluged into the adaptronic to listen for knock... but seeing that I just blew up my volvo the other night... I am feeling wary of my skills. (Bent 2 of the 5 rods) :(
Anyhow, I would love to know what you guys suggest for this little turbo. If there is any suggestions on duty cycles on the wastegate actuator for given RPMs and load ranges... I'm open for that.
Right now I am simply running target boost at 190 KPA at 100% duty... just to be safe.
Thanks all and good to be back!
Cheers,
Matt

Yeah, I think you are about where you need to be with it. If you would allow me to preach, I don't think you need to be wringing the hell out of your car when you just nuked your other one. That being said, if you are like me and will anyway, I would leave boost about where it is as long as you have no knock. Oh and to elaborate on what Sav was saying..... 0 kpa equals 100%ish Vacuum. 100 KPa equals atmospheric. (should be about 100 atleast. This is what you breath.) Anything above 100 or 101 as some people do is considered boost. If you turn your ignition on, not your engine, your map should read somewhere near 100kpa while the engine is off.

atmo is whatever pressure reading currently in the space your car takes.
sea level is around 14.7~psia\101kpa~ if you live higher alt or weather changes may also change it. I"ve seen from 99 to 101 locally, I"ve also start at 100 at my house and only 30 minutes away its gone down to 99.
so basically note what current baro is and anything above that is considered boost.

Thanks for the input y'all FWIW... I didn't kill my other car, irony is my EBC actuator had a line pop off in a boosted run. She overshot like mad but by the time I backed off... I had the death knock :(
Soo for now I will leave my boost just where it is
Thanks again all! Cheers,
