I'm not sure where to start this topic so im sry if it is placed wrong. let me know and i will start it in the correct field.
I have just acquired an 89 hr32 rb20det, it has an apexi fc pro in it and have no idea as to how it works. I have been looking around the net for manuals but havent been able to find one. Could anyone plz help me with finding one or better yet could you plz tell me how it works and how to tune the car with it.
First thing that i am looking at is idle hunting, the car is hunting when ever i come to a stop or start the car and im curious as to why this is, if it needs attention and if it should be changed.
Thanks in advance for any advise
