So I got my S-AFC II in the mail today and I installed it a few hours later. After I installed it I turned the car on and noticed my idle is really high at 1500rpm. Then I take it out for a lil test drive and its running like **** Around 2000rpm it loses all its power so I shift to 2nd and same thing happens. What should I do!!! My car was actually running pretty decent before I installed it in and now its running like complete ****. Im afraid to mess with any of the settings cause I dont wanna mess it up anymore and I wont have the money to tune it for a lil while. Does anybody know if theres any reset to switch it back to default settings or can any1 help me out. Somebody please help me!!!

 

Did you even tune it?

Also, do you have a wideband?

Do you have things like:- Boost gauge, MBC?

 

make sure that you have all the settings correct to. Like the throttle position and set it for karman and the # of cylinders. For some reason some cars will actually want the cylinders to be set to 2 and not 4. Try both and see what works. Make sure everything is zerod out as well first.

 

dont forget the arrow on the setup has to be the upward diagonal arrow the number of cyl may need to be set up for 2 not 4 and you may have wired the A\F wires in wrong like I did on mine at first
