Hi All,

wondering if some of you could help me out with some data from S4 and/or S5 NAs.
I need to know the voltage returned to the ECU from the AFM in two conditions -
at idle; and up around redline - full throttle.
I'm sure the SAFC will monitor & display this if selected through the menu. Note this is the "Sensor Check" parameter ( a voltage number), _not_ the AFL %.

Thanks to all!

From the FSM on the S4 car.

Idle = 2.5 to 3.5 volts.

Just to clarify for all - I'm looking for actual measured numbers, to the tenth of a volt.
The FSM value is 'key-on', not engine running.
I'm looking for real world data, with engine running at idle, and if possible full throttle at, or close to redline (ie. maxed out AFM).
Unfortunately my car is out of commission at the moment.............

Thanks again,

Lemme guess....

You have an SAFC, and the throttle voltage input for an S4 TPS isn't good enough. So, instead of using the narrow range S4 TPS, you are thinking about using the AFM as a substitute? Am I right? If so - Interesting idea!

I plan on using the vaccuum (or boost) sensor for my SAFC instead of the S4 TPS. Once the car comes out of storage I'll get on that!

In the mean time, if that is you plan - to use the AFM - let us know how it goes!
