I have a GRT EIS4000 and need some help figuring out the wiring. I am using 5 aux inputs.
Aux1 - MAP
Aux2 - Left fuel (Steward-Warner float sensor)
Aux3 - Right fuel S&W (float sensor)
Aux4 - Hall effect current sensor
Aux5 - Fuel Pressure
I have run the 4.8V from the EIS to a terminal block (See picture). There are 6 of the terminals being used. Left to right:
Top ROW -
[Fuel SU Lft] [4.7V Jump] [4.7V Feed] [4.7V Jump][Fuel SU Rt][OAT]
Bottom ROW -
[Aux2 input Lft, 470Ohm] [470 ohm][3, 4.7V sources out][470 ohm][Aux3 input Rt,470ohm][oat].
The display is: Aux2 = 38, Aux3 = 40
I have both Aux2 and 3 set up as Integer display
Both AuxSF = 100
Both AuxOff = 0
The tanks have approximately 9 gallons of fuel at the moment. Any ideas what I have done wrong?
The MAP is reading crazy too. I used the two values that were supplied with the MAP sensor: AuxSF= 199, AuxOff = 62. I have it set up on Aux1 port and am getting a 3.1 readout ambient ( motor not running) Shouldn't if be close to the current BaroPress reading at the time? This thing is really kicking my ***. Anybody have any suggestions?
