Little help here on Jspec swap.
hey fellow rotorheads, just swapped in a jspec s4 tII into my 87 tii and its running rich as all can be. new o2 sensor, 3in turbo back with cat, removed/blocked off acv, airpump, twin scroll, egr, and capped all vac lines on the back side of the lim between the firewall (for the acv and twin scroll) and for the egr. i am curious if i need to swap out my bac so that i have an idle adjust (as i am idling at like 400rpm) and adjust the variable resistor some to correct this mishap. right now i have to have my safc @ -20% from 1000 down to keep it from dieing everytime i come to a stop. any ideas? oh yeah i kept the jspec injectors and im running a greddy type s bov. and teamfc3s.org fcd.

Check your BOV. I had a similar problem and it ended up being that my BOV was leaking slightly at idle.
I also have a j-spec motor installed. After removing the BAC, I just had to turn up the idle adjustment screw on the TB a little to make it idle where I wanted.
