Arite i dont know anything with the apexi S-AFC. ive been havin idle problems as some of you might already read my other threads =\. i changed my vac lines and kept havin this problem untill i messed with my s-afc. I DONT KNOW how to tune it but all i want to do is raise my idle. My car runs great but she acts like she wants to die at stops and doesnt cuz the idle so damn low. Any help is apreciated!!!! i bought the car w/ it installed so i don't know anything about it only that i left it on the original settings until it was messed with so i just played around until i got her running. HELP ME..

 

you can set/raise your idle as per the FSM (4B-80 Idle speed and idle mixture).
