So, in the midst of my engine build on my TT 3.7 I'm building a variable boost controller. To do this I need to know what the voltage output of the speed sensor is at 60mph and at 80mph. Obviously I can't do this myself while my car is down. So, if somebody can please get me these readings it would be an enormous help. I would think any pro-level diag computer like a Modis or Solus should be able to get these readings.

Thanks!!

Are you sure it's a voltage?
I would think it would be a digital signal of some sort.
Perhpas a pulse train, that some other computer measures the frequency of?
Thats just the way I would do it if I was designing the electronics in a car.

Ya know, now that you mention it I'm not sure. It maybe something I have to get creative with.

157dB

Its not a voltage.
Its pulses like a crank trigger.
A frequency counter would be needed to do this.
And a silly scope to verify the correct signal.
I have the equipment and knowhow but not the vehicle.
