Anyone have a bin file for turbo st5 cam? The fuel trims wont settle down, and I also cant get it to idle cold without holding the pedal for a few seconds. I'm using a north star t/b only bc its the only tb i have that can adapt to l26 intake. I adjusted the throttle screw ( as far as a could with maintaining 30-50 warm) but the iac still maxes out and cant maintain rpm, once the engine is warm the iac sets at 30ish like normal.
 


Did you use the IAC for the N* or use your Lwhatever IAC? They are different. If you didn't you'll either need to swap the pig tail connectors or get the zzp iac > N* adapter.
 
Yea its the right iac and harness. Im borrowing this tb and adapter from my fiero and it works fine for it.
 
Yea its at 950-1000. Like i said before the iac maxes out but its not enof to keep it running at cold idle. I could try increasing the throttle plate screw, but iac is already sitting at 30 when warmed up.
 
Hey neighbor,
Have you had any luck with this? I am trying to help a friend with a st5 turbo build as well.
 


Hey, its coming along but not done tuning. Ill be putting the l67 tb back on tonight since I have an adapter now. This should fix the idle.
