Hi fellas , I wanna wire the FJO controller but without the the FPSS that shown in the diagram below , how it goes without the FPSS ? , Also i have AEM Fuel pressure gauge and AEM wideband Air Fuel gauge can i connect one of them on the controller ?

please check Diagram below and let me know




and please check if this is correct or not without FPSS , that i edited check diagram below

 

anyone can help ?

 

The second one is correct without a FPSS. The first one is for two systems. I believe you just ground pole 85 from the relay (or both if 2 systems) rather than grounding it through a FPSS. The FPSS basically just breaks the grounds to the the solenoids if pressure drops too low. If you want to go without the FPSS, just ground the relay and there wont be anything to interrupt it.

 

thanks Sean appreciate your help , i'll go with the second diagram .

 

Second diagram FTW....

 

thanks bro , but can i connect one of these gauges ( Fuel pressure gauge or wideband Air Fuel gauge instead of FPSS ?
