hks pfc fcon question
 
So recently got my 10th anniversary up and running and now am wanting to play with getting a little more power out of it. The car has an Hks PFC fcon ecu, an Hks fcd,and Hks up pipe and bov. The car had a manual boost controller on it but I took it off because it was a piece of garbage. I will be buying a new MBC, a wideband, and a boost gauge and attempt to crank up the boost a bit. My question is does anyone have experience or know what the maximum safe boost level with running this fcon ecu would be?

After 10 psi you don't get any benefit of power as the stock turbo will be fighting itself.I don't see any fuel system alterations( bigger injectors) or aftermarket turbo,so your Boost is pretty well gonna be around10-12.
any more than that,you may as well get some jam..your engine will be toast.

So conservatively I could set it to 10 psi and the stock fuel system and motor would handle that reliably? Car has low miles, only 85,625 to be exact if that would make any difference.

Also I'm not sure if it has fuel system upgrades yet, I bought the car and it had a bunch of Hks stuff on it so who knows what else is done to it till I dig deeper. Safe to assume it is stock for the time being though.

I'd find out Exactly what you have before you start Farting with the gadgets on it..Then go from there.Play it safe,this is not a one dollar experiment.
It's like Ikea furniture..you'll KNOW why you had extra bolts left over..when it falls apart.

Sounds good, is there an easy way I can check out the injectors while on the car? It is at stock boost currently because I took the boost controller that was on it off and it seems to be running fine not rich as far as I can tell. It does eat fuel like no tomorrow but to my understanding rotaries aren't the most efficient in that manner anyways.
