Wiring Fuel Level Sensor into Electronic Dash
Trying to wire a stock plastic tank fuel level sensor on an 04 996 Cup into an electronic dash. The range of the unit reading in ohms is VERY small. The AIM dash can read the small change in resistance. Anyone wire one of these into a dash?

The AiM dash only reads voltage. You have to wire in a resistor to change the resistance reading to a voltage reading and build a custom sensor for it. You can also go this route http://www.ironcanyonmotorsports.com...l#!prettyPhoto

BimmerWorld also sells an adapter.

Bob, I have done several using MoTeC. You'll need a 5v pull up resistor circuit wired in to the AIM so it will read voltage. The MoTeC will read resistance on a temp channel so no circuit is needed there.

Have you measured the resistance change on the cup fuel sender? Bob was having issues partially because the resistance change was so small. I expected to see 100+ ohm change.
