I just got my car upgraded (and blew out my diff on my first run ), anyway...I was curious what others with similar mods have for a boost setting on primary and secondary turbos with the power FC.



I'm interested to run about 13.5 to 14 lbs.



I have 1200 CC injectors, fuel pump, power FC, rx7fasion cold air box, dp, catback , power fc, and other stuff.



Thanks!

 

If your injectors are running over 85% that is not good. Im sure you may get by for a while. I have about the same mods or more & I rarely take it over 12psi. You could , I just don't. I use the purple box though.

 

I ran 12 on the stock fuel system. I upgraded so I can run more at the track. NOT on the street though.

 

I ran 850 cc X 4 at stock fuel pressure and boosting appx. 14 to 15 psi at 79% injector duty. With your 1200 cc injectors X 2 you'll be fine.

 

if you havent had your pfc wideband tuned yet...do so

i would do the following...



first tune...desired street boost level...as your first boost setting in commander...end result would be your street map

second tune....desired track boost level...as second boost setting in commander.....save this map for track use recall...



1300cc with nippondenso

have spiked to 13lbs...inj duty cycles have not exceeded 65%

tuned conservatively for 10lbs with the occassionaly 1psi spike due to mp and un-ported wastegate..

attribute the additional to lower temps...need to play with my base duty..

 

it was tuned by Rx7fashion.com. After he does the maps he takes it out on the road with a wideband, but not on a dyno. I will do the dyno thingy one of these days.

 

id be wary of mailorder tuning...

 

I live near RX7fasion, I leave my car with him and he tunes it, then I pick it up. He hooks a wideband o2 gauge up to the car and takes it on the highway after he tunes it.
