ok i got a s-afr, and there is a blue wire that isnt shown in hks diagram, it looks to be (u) which is a extra 12v, but the tach voltage, do i need a digital tach adapter?
"Connect the brown wire to (I) the RPM signal. [Must be a used with a 5V digital signal - For applications with an analog signal, a HKS REV-ad - signal adapter (PN # 4599-SA002) must be used.]"

and then which maf voltage do i have with a z32 maf, i have a jwt ecu so its tuned for it but i m unsure of the voltage?. "
Air Meter Type Selection
The DIP switches allow for the selection between Hot Wire, Karmen Vortex, and Pressure sensor calibrations for the Super AFR. The airflow meter type settings are made with the combinations of DIP switches 1 and 2 as listed below.
Hot Wire (0-5V)
Hot Wire (5-0V)"

did a search and found alot of other peoples unanswered q's hopefully someone can help me.

oh yah i have a ka24de
