Anyone familiar with the HKS S-AFR? Its the same type of piggyback fuel computer as the Apex AFC.
Anyway, the problem i have is when I have it in 4cylinder, Karmen Vortex mode (which is our cars right?) I get a rough idle, it misses erratically. It also misses and stumbles erratically all the way through the RPM band. I would think that the thing was defective or I wired it wrong, except when I set it to ANY other type of air sensor (0-5v, 5v-0, pressure) the car hums like a kitten.
I have adjusted the idle control, and fuel gain at low rpms every which way with no change, it still stumbles. When I bypass the AFR on the white MAS wire the car is as usual. Anyone have any ideas what is wrong?
