Ahmed Hammad Posted February 20, 2023 Report Share Posted February 20, 2023 Hi guys, i bought AEM 30-0310 controller without gauge, so i need to wiring it on as CAN BUS mode on my monsoon G4x, to make ECU target the AFR * Is there is any Physical resistor must be added on loom before the controller or what? * It that can transmiting data rate faster than that we wiring it on An volt? * if i make lamada AFR target 14.7 on cruising use that will be fine? Pls, Advice What the process pls? Quote Link to comment Share on other sites More sharing options...

Yes you should fit a 120ohm resistor across CAN H/L somewhere close to the wideband device. 8 hours ago, Ahmed Hammad said: It that can transmiting data rate faster than that we wiring it on An volt? CAN is more accurate due to no ground offset issues, I do not know how the update rate of the AEM CAN bus message and analog signal compares. I would expect either method will be plenty fast enough for closed loop control. 8 hours ago, Ahmed Hammad said: if i make lamada AFR target 14.7 on cruising use that will be fine? Cant really answer this, the required lambda target will depend on many factors, environmental conditions, engine design, fuel chemistry, and the application or end use. A user that wants best fuel economy will have a different target than a user that needs to meet emission requirements or a user seeking maximum torque etc. 8 hours ago, Ahmed Hammad said: What the process pls? Connect CAN wires, CAN set up instructions are in the help file. Quote Link to comment Share on other sites More sharing options...

Hmmm.. Before the wideband controller? Quote Link to comment Share on other sites More sharing options...
