All,

Just want to post my config for interfacing an ICM Fuel level sender with an Aim sport dash.
This same setup could be used for any other logger/dash that takes 0-5v analog inputs.

ICM sender was ordered as :
Min and Max ohm values: 11ohm min (full tank) / 132ohm max (empty tank))

I opted for the 719 binder connector to hook directly into the analog harness of the Aim Dash, be sure to use one that is provided vB (battery voltage) output on the harness.
Fuel sensor was connected to the ICM box using C8 of the instrument cluster wiring.



I pumped out the tank until the car wouldnt start and refilled ~1 Us Gal at a time.
Car would not restart until > 2 gal was pumped into the tank. So the 1 - 2 Gal readings were taken with nominal battery voltage.

These are the values taken from the live measure on my system. All units are in mV.

0 gallon 3450
1 gallon - 3450
2 gallon - 2920
3 gallon - 2560
4 gallon - 2390
5 gallon - 2244
6 gallon - 2040
7 gallon- 1867
8 gallon - 1704
9 gallon - 1513
10 gallon - 1266
11 gallon - 1060
12 gallon - 790
13 gallon - 790
