ANALOG #1 INPUT FUNCTIONS
1) Fuel Level S-W – Fuel amount, in percentage, can be measured and displayed on the C3
module using a standard Stewart Warner scale sender of 240 ohms – 33 ohms. 240 = Empty
and 33 = Full. Sender ground must be common with battery negative.
2) Fuel Level VDO – Fuel amount, in percentage, can be measured and displayed on the C3
module using a VDO scale sender of 10 ohms – 180 ohms. 10 = Empty and 180 = Full.
Sender ground must be common with battery negative.
3) Oil Pressure PSI – Oil pressure, in PSI, can be measured and displayed on the C3 module
using a standard Stewart Warner scale sender of 240 ohms – 33 ohms. 240 = 0 PSI and 33
= 100 PSI. Sender ground must be common with battery negative.
4) Oil Pressure bar – Oil pressure, in bar, can be measured and displayed on the C3 module
using a standard Stewart Warner scale sender of 240 ohms – 33 ohms. 240 = 0 bar and 33 =
7 bar. Sender ground must be common with battery negative.
5) Oil Pressure VDO PSI – Oil pressure, in PSI, can be measured and displayed on the C3
module using a standard Stewart Warner scale sender of 10 ohms – 180 ohms. 10 = 0 PSI
and 180 = 150 PSI. Sender ground must be common with battery negative.
6) Oil Pressure bar – Oil pressure, in bar, can be measured and displayed on the C3 module
using a standard Stewart Warner scale sender of 10 ohms – 180 ohms. 240 = 0 bar and 33
= 10 bar. Sender ground must be common with battery negative.
7) Rheostat – Speed control can be accomplished by connecting a 5 K potentiometer in series
with the flex analog input. Engine speed will vary with the change in resistance value.
8) 0 - 5 VDC – Reserved for OEM applications.
9) Ratiometric - Reserved for OEM applications.
10) 4-20mA - Reserved for OEM applications.
11) None – Set to None when no functionality is required.
