Technical Questions - For You Experts!

I have three questions, one of which I think I know the answer to:
Are the OEM injectors the high impedance type? (I believe the answer is yes)
Are the OEM ABS wheel speed sensors passive (magnetic inductive) or active (magneto resistive)?
Can the misfire detection be disabled when using the OEM ECU?

These are all requirements to use the RaceLogic Traction Control system.

Are the OEM injectors the high impedance type? (I believe the answer is yes)

WRX uses high impedance top feed injectors
04-06 STI uses high impedance side feed injectors (also called bottom feed)
07+ STI uses high impedance top feed injectors

I do not know if misfire detection can be turned off internally on the ECU, but the OBD misfire codes can be set to "off" -- Basically they can be told not to trigger a CEL and not store a code.

Misfire monitors can be turned off on the stock computer.

Anyone know about the ABS wheel speed sensors???
